Hey everyone, TravyMcNavy184 here with the next chapter of The Son of Satan in Yokai Academy. First off, thank you everyone who favorited and followed my story. When I got the Emails of all those faves and follows, it just felt awesome. Like I said I am new to writing fanfiction and to know that people like my story is just an amazing feeling so thank you everyone. To start off, this was a pretty long chapter to write, but I tried my best to keep the elements of the first episode of the anime true and incorporating Rin in it was a bit of a challenge, so I hope everything makes sense, if not let me know and ill fix it. Anyway,, here is the next chapter. As always, I own nothing but the OCs.

Chapter 1

First Day and Fight

Now that the orientation was over, the older Okumura twin found himself in his new dorm room. It was pretty basic in design. It consisted of a bed, a closet, a dresser, a desk, a fully functional kitchenette, and a bathroom. All in all, it was perfect for a single person. Right now, Rin was unpacking his belongings, which were delivered via magic from his old room at True Cross Academy.

He put his clothes in the dresser and closet. Right now he was unpacking his personal belongings; his posters, personal nick-nacs, and pictures, which he hung on the wall around his bed and placed on his desk. He grabbed a picture from the box and looked at it. It was a picture of him and his brother Yukio at the beach when they were little kids, taken by their adoptive father Shiro Fujimoto.

He looked at the picture with a feeling of nostalgia, remembering it was one of the funnest memories he spent with the two. He then looked at the younger Yukio and suddenly, the feeling was gone as he realized that he is at the new school partially because of his brother. At that moment, he opened a desk drawer and tossed in there. He then put his hand on the corner of his desk, tightening his grip around it. 'Yukio, have I really fallen so hard that you hate me now? Enough to send me away. Tch, if anything, you're probably glad I'm gone. Whatever, you're strong enough to take care of yourself so what do I care.' He thought in anger. He then looked to the clock on the wall and realized that it was almost time to report for his homeroom class. "Oh crap, I'm gonna be late."

He grabbed his bag and headed for the door. He exited his room, lock his door, and ran with the rest of the boys who were also heading to their homeroom class. Little did Rin know, the edge of the desk he grabbed was ultimately destroyed from grabbing to hard.

Rin was currently walking through the hall looking for his homeroom class. "Let's see, room 1-3. Room 1-3...Aha, here we are." He slid the door open and stepped inside. He was treated with the appearance of a certain black haired human. "Hey Tsukune, you're in this class too?"

"Yeah and it looks like you are too Rin. Lucky us, huh?"

"Hell yeah, this is going to a fun year."

"Alright everyone please take your seats." A new voice came into the room and everyone followed it's instruction. Tsukune remained at the desk he was at while Rin took the seat in front of a girl with blue hair. With everyone seated, the students got a look at where the voice came from. It was a woman who stood at about 5'8" and had a bombshell figure. She had sandy blonde hair with what appeared to be cat ears on the top of her head. The most notable thing about her is the long cat tail coming from under her skirt.

"Hello everyone and welcome to Yokai Academy." she greeted her class with a cheerful expression. "My name is Shizuka Nekonome and I'll be your homeroom teacher this year." The now named teacher introduced herself and Rin and Tsukune just couldn't but fell like they lucked out getting a teacher who seemed to just ooze kindness. 'Wow, even the teacher seems nice. How lucky can one guy be?' Tsukune thought to himself.

'Wow, a nice teacher. I never had anything like this when Yukio was my teacher. I think I'm gonna like it here.' Rin happily thought.

"Now everyone, as I'm sure you are aware, Yokai Academy is a school for monsters." Miss Nekonome announced not beating around the bush.

'Sure, school for monsters. Wait, what?!' Tsukune thought processing what his new teacher just announced.

Rin then became wide eyed when he realized that he forgot to tell Tsukune that Yokai Academy was a school for monsters.

"Now, rather we like it or not, the planet is currently under the control of the humans. So in order for monsters like us to survive, we must learn to coexist with them, which is precisely the purpose of this school." Said Miss Nekonome, not losing her smile. "Which brings us to our first rule, while on campus you must always remain in human form. Rule number two, You must never reveal your monster identity to anyone. Rule number three-"

"But teach," one of her students spoke up. "Wouldn't it be better to just eat the humans, maybe even have a little fun with the women." He said with a lecherous grin on his face. Rin found the student who the voice belonged to. The student was a tall, lean boy the same age as Tsukune and Rin with slicked back brown hair, piercings, and rather large, muscular build. One look at this guy and Rin could tell this guy was going to be trouble.

"Let's see, you are...Oh, Saizo Komiya. Well Mr. Komiya, there is a very powerful barrier around the school that prevents detection from the human world. And even if a human managed to find their way in here, they would be killed immediately." At that Tsukune freaked out and accidentally knocked over his notebook, scrambling to pick it up.

"Say what you want, but I swear I could smell a human this entire time." Komiya said with a wicked grin, causing Tsukune to freak out even further, trying his best to hide it. He knew if it got out he was a human, it meant an autmatic death sentence. Seeing his friend in distress at being ousted as a human, Rin decided to do something about it.

"Oh really, is that really a human you're smelling or something entirely different you worthless piece of crap." Rins said getting the attention of everyone in the room.

Saizo didn't take kindly to the son of Satan's words. He got up from his desk and walked towards Rin. Rin doing the same until they were in front of each other. Saizo easily towered over Rin by a good few inches, but Rin was undeterred. "You got a problem with me you little squirt?"

"There are several things in this world I have a problem with: insects of all shapes and sizes, gutless little pricks who pick on animals and people who can't defend themselves, and finally filthy maggots like you who see women as nothing but tools to use for your sick urges. So yeah, you could say I have a VERY big problem with you." Rin proclaimed to the half-wit thug in front of him, gaining an angry expression from him. When it looked like all hell was about to break loose, Miss Nekonome jumped in to stop it.

"Now, now boys, come on now, there's no need to start a fight, especially on the first day of school." She said desperately trying to diffuse the situation.

After a few moments, Komiya back down. "You're damn lucky we're in class right now squirt. If not, I'd kick your ass." Komiya said to Rin walking back to his desk. Rin on the other hand just flipped him off with both hands and mouthed "fuck you!" to Komiya before taking a seat back in his own desk.

At that moment, the door slid open again. "I'm so sorry I'm late, I got a little lost." Said the voice. Tsukune and Rin looked towards the voice and realized it belonged to Moka.

"Oh don't worry, why don't you come in and introduce yourself."

"Hi, my name is Moka Akashiya." She introduced herself with a smile on her face. Immediately, all the boys in the class became enamored with her. Moka then looked to the back of the room and noticed Tsukune and Rin. Her smile grew even wider as she flew across the room and tackled Tsukune nearly out of his seat. "Tsukune, it's you! I can't believe were in the same class. And Rin too. This is so great!" She exclaimed never losing her smile.

"Yeah, lucky us, huh?" Tsukune chuckled. Both boys then noticed that the boys in the class were literally giving them death glares. The saying goes if looks could kill. Well if that were true Tsukune and Rin would be dead a thousand times over. 'Well, so much for keeping a low profile...' both boys thought at the same time.

It was the afternoon and the students had free time. Most of the students were chatting amongst themselves. Others were just walking around the school to get a better feel for the school, and others were just lounging about. Tsukune and Rin were right now on the roof. After class, Tsukune ran into Rin and asked Rin to go with him to the roof of the school to talk to him and Rin had a good idea what he wanted to talk about.

"Rin, was Miss Nekonome serious?! Is this place seriously a school for monsters?!" Tsukung asked frantically.

"Yeah she was serious Tsukune." Rin answered.

"What the hell Rin?! Why didn't you tell me?!"

"I-i-it slipped my mind! I'm sorry. Tsukune, I'm sorry, I was going to tell you this morning, but then we ran into Moka and I kinda forgot about it."

Tsukune then started to frantically walk back and forth with his hands grabbing his head. "Oh, this is bad! Really, really bad!"

"Tsukune, you're way overthinking this. Calm down man." Rin tried to console his frightened friend.

"No, I will not calm down!" Tsukune shot back. "Rin, if people find out what I am, that's it man! Game over! My goose will be cooked! They're gonna-"

SMACK

Rin could see Tsukune was on the verge of having a heart attack, so he smacked him upside the head. It was enough to get Tsukune to stop talking and it somehow managed to calm him down. "Thank you, I needed that." Tsukune said gratefully.

"Anytime pal." Rin answered. "Look, Tsukune, I'm sure that this is some kind of huge mistake. I'll tell you what, after classes today, I'll go with you to the headmaster's office and see if we can get this straightened out." Rin offered.

"But Rin, what if-"

"Tsukune, if he or anyone else tries to hurt you, I'll deal with them. Don't worry, I got your back."

Hearing that made Tsukune smile as a sense of relief washed over him. "Thanks Rin."

"You bet." Rin replied giving him his trademark smirk and a thumbs up. "And Tsukune, I think it'd be best if you avoid telling Moka you're a human, alright."

"Yeah, don't gotta tell me twice."

The boys heard the door open and as the saying goes 'speak of the devil'. Moka had appeared and smiled at having found her two friends. She happily walked up to the two.

"Tsukune. Rin. There you two are. I've been looking all over for you." She said.

"Ah, sorry Moka. I ran into Rin after our classes and thought maybe we'd get a good view of the school from the roof." Tsukune said scratching the back of his head.

"Sorry Moka, we didn't mean to make you think we ditched you or anything." Rin added.

Moka shook her head. "Oh no, don't worry about it. I'm just glad I found you both." She replied. "Hey, since we got some free time, you wanna walk around the school?"

Tsukune and Rin looked at each other and then back to their pink haired companion. "Yeah sure, Moka." Tsukune answered.

"Yeah, sounds like fun." Rin replied.

Moka's face soon grew a mile long smile as she wrapped her arms around the other two boys' arms. "Great! Let's go." Moka then nudged the two boys and the three friends headed into the school building.

Hallway

Moka, Tsukune and Rin were walking together, Moka with one of her arms around Tsukune's arm and the other around Rin's. "Moka, ease up will you, at this rate, you're gonna rip my arm off with the way you are yanking on it." Tsukune said to the vampiress.

"I'm sorry Tsukune, I'm just so excited at being here."

"Relax Moka, it's not like Tsukune and I are going anywhere."

They then stopped at a vending machine to grab something to drink. All the while the male population looked on in jealousy at the two boys who had somehow managed to befriend the beautiful girl. Moka got a can of tomato juice while Tsukune got a coffee drink and Rin got a water. They got their drinks and sat down on a bench to enjoy them. While they were enjoying themselves, an all too familiar voice interrupted their peace and quiet.

"Hey there sexy. You're Moka Akashiya right? You're pretty cute." they looked and saw that it was Saizo Komiya.

"Um...thank you" Moka said nervously.

Saizo then grabbed Tsukune by the collar of his shirt and raised him off the ground. "So I gotta ask, what's a smoking hot chick like you doing with a couple of weaklings like them." Saizo arrogantly said with a smirk on his face.

"Tsukune! Leave him alone." Moka shouted at Saizo as she tried to loosen his grip.

"Put Tsukune down you jerk!" Rin shouted at the bully holding his friend up.

Saizo then threw Tsukune at the vending machine, causing some of the students to watch as the events unfolded. Rin ran to help his friend and Moka was about to follow suit, but then Saizo grabbed her arm. "Come on babe, why don't you ditch the weaklings and come hang with a real man." Said Saizo.

Moka brushed his arm off of her "No thanks, I prefer to hang out with nice people." Moka shot back at him and she ran towards Tsukune. While they were tending to the human boy, Rin could hear Saizo chuckling rather arrogantly. He looked towards the bully with anger in his eyes.

"You think this is funny Saizo?" Rin asked rhetorically. "Well if you thought that was funny, here, let me show you what I think is funny." Rin grabbed the vending machine with one hand and threw it towards Saizo. Saizo saw it coming and knocked it out of the way. Suddenly, Rin appeared in front of him and punched him in the face, sending Saizo flying through the door behind him and crashing into a wall, knocking out a few of Saizo's teeth in the process. Rin went to Saizo who had blood coming out of his nose and mouth, grabbed his face and made him look at him.

"Consider this a warning you creep. Come near me, Moka, or Tsukune again, you're gonna end up with a hell of a lot worse than a broken nose and a few missing teeth. Ya understand?!" He threw Saizo to the ground and walked away, ignoring the onlookers who stayed and watched the events that unfolded. Rin walked to where Moka and Tsukune were and proceeded to help the poor boy up and away form the area. As they were walking away, Saizo got back on his feet and looked towards the three with an furious look in his eyes directed at the dark blue haired youth.

"Nobody makes a fool out me and gets away with it. Mark my words you little worm, you will pay for this." He said to himself as he spat out blood from his mouth.

The Roof

After the little scuffle with Komiya, Moka, Tsukune and Rin found themselves on the school rooftops overlooking the rest of the school. "Wow, that was intense. Are you alright Tsukune?" Moka worriedly asked.

"I'm fine Moka, don't worry about me." Tsukune said reassuringly.

"Well I'm glad you're alright Tsukune." Moka said sweetly to him, making him blush. She then turned her attention to Rin. "And Rin, I thought it was amazing how you handled that creep back there."

"Yeah, that was pretty awesome what you did."

Rin just blushed at the praise and scratched the back of his head. "Hey it was no problem. I've dealt with my fair share of assholes like him back home. Knocking him into next week actually felt pretty good." He said with a grin on his face.

Moka's smile grew wider at her friends words. "But still, I don't want my only friends to get into trouble or get hurt because of me." She said standing next to him.

This statement came as a shock to the boys. "Wait, we're your only friends? A nice, cute girl like you has only two friends. You should have people lining up to be your friend." Rin said in surprise.

"I know right, how is it that someone like you doesn't have a lot of friends?" Asked Tsukune.

"Well...the truth is I'm not good at meeting new people and making friends. Besides, you're the first person I've ever drank blood from." She said to Tsukune with a smile on her face.

"Ohhhhhh. So in a way, he was your first." Rin said with a chuckle and getting a blush out of both Moka and Tsukune, who in turn smacked him on the back, really hard.

"Rin, don't say it like that, you make it sound dirty." She chastised her friend not losing the hint of red in her face.

"Right. Right. I'm sorry, I couldn't resist." Rin said not losing his grin.

They stood in silence for a few moments until Moka decided to break the silence. "Umm, Tsukune, Rin, if you don't mind me asking, what kind of monsters are you?"

"I thought revealing your monster identity was rule number one at this academy." Tsukune stated

"Oh, that's right, I forgot." Moka said with an embarrassed tone. "But I already told you I'm a vampire. Wouldn't it be fair if you told me what you are."

"Yeah that's the thing, you don't seem like a vampire appearance wise." Rin stated to Moka.

"Oh, that's because of this." Moka said opening the top of her shirt revealing a good amount of cleavage in the process. Tsukune quickly became red and averted his gaze while Rin gained a small nosebleed, but hid it from the two.

"Moka, where are you asking us to look?"

"At the rosary silly." She said with a chuckle. "When this rosary is removed, I transform into my true self. A true vampire, and I can be very scary."

"Wow, a real vampire?" Asked Tsukune.

"That's why I wear it. As a charm to seal my powers away. I can't even take it off myself." Moka further explained to the two.

"Well, that's okay. Even if you get a little scary sometimes, I sure you're still the same Moka." Tsukune affirmed.

"Yeah, even if you become terrifying, I bet you are still the kind sweet Moka we both come to know." Rin added.

Hearing what they said caused Moka to smile brightly and she ran up to the two and hug them both. "I knew you both would understand. You two are my first friends here." Once she got close to Tsukune, she got a whiff of him and she began to shiver. "Tsukune...I'm sorry, you just smell so good. I-I-I just can't resist anymore." She closed in on Tsukune's neck to drink his blood, but just then Tsukune back away from her.

"I-I'm sorry. I...have to go. See you guys later." Tsukune said as he took off in a run in the opposite direction.

"Tsukune, hey what's wrong?" Rin tried shouting but got no response from his friend.

"What do you think that was about?" Asked Moka.

"I may have an idea, but I really hope I'm wrong."

Later, After school

Tsukune then found himself in the front of the school with his luggage. 'I don't think this school is for me.' He thought before he took one last look at the school and turned to the direction of the bus stop until he heard someone call his name.

"Tsukune." He turned around to see a familiar pink haired vampiress and dark blue haired half demon close behind her. Moka had a worried expression on her face while Rin seemed somewhat neutral.

"Moka, Rin."

"You were acting kinda weird back there, are you alright." Moka asked her friend.

"I'm sorry Moka, but I think I should just go to a human school."

"A human school, but why?" Moka asked. Tsukune then turned to his companions

"Look, Moka, I really like you and Rin both, but I just can't stay here." Moka didn't like the sound of his words and ran towards him and grabbed his bag to try and stop him.

"Tsukune you can't go to the human world. Humans, they can be cruel and mean. I know because I went to a human school all the up to junior high. The humans, they ignored me, made fun of me because I was different. I was so lonely, they made me feel like it would be better if I just disappeared. I hate humans greatly." She said to Tsukune with tears threatening to fall from her face. Tsukune just stayed silent the whole time.

After calming down, she looked into Tsukune's face still with tears but a smile on her face. "But then...I met you and Rin. And you both said you didn't care that I was a vampire and were more than willing to be my friend. And for the first time in my life, I didn't feel so alone."

"But still, what if I turned out to be one of those humans you hate so much, would you feel the same way then?" Tsukune asked in a cold tone.

"Tsukune think about what you're saying?" Rin jumped in.

"I'm a human. I'm sorry Moka, but that's what I am and the only reason why I'm even here at is because of a major mix-up."

Rin already knew Tsukune was a human so he wasn't surprised, but Moka looked like she was shocked to her core. Moka even let go of Tsukune and backed up a few steps. "You're lying, you have to be. No human could get in here." Moka said with fear in her voice. She didn't want to believe that one of her first real friends was a human. She then looked to Rin. "Rin, please tell me it isn't true." She pleaded, hoping that Tsukune was lying. Rin just looked away from her, further shocking her.

"I should have known you would look at me that way Moka."

"Tsukune, come on man, everything is going to be fine. Let's just go to the-" Rin tried to say until Tsukune interrupted him.

"NO! JUST STAY AWAY FROM ME! You said you hate humans, right Moka? What about you Rin, do you hate them too?"

"Tsukune, will you just listen-"

"Well that's OK. I don't need you. Either of you. I DON'T NEED MONSTERS FOR FRIENDS ANYWAY." Tsukune shouted, shocking Moka. Rin on the other had adopted an angry scowl that Tsukune could say something like that. With that, Tsukune took off into a sprint to the bus stop.

"Tsukune wait!" Moka shouted, but to no avail. Rin grabbed her shoulder, causing her to look at him.

"Moka, go back to the dorm and wait for us, I'll go get him and set him straight. After that, we'll get everything straightened out" With that Rin took off after the human. Once Rin was out of sight, Moka took off after the two, hoping maybe she could help in convincing Tsukune to come back.

Tsukune was still running to the bus stop, the words he said to Rin and Moka still fresh in his mind. While he was running, he realized he didn't know where the bus stop was. 'Where's the bus stop? Is it this way?" While he was pondering this, he didn't notice a blur coming right at him.

BAM

Tsukune then found himself on the ground and a very familiar figure standing over him and looking very cross. "Okay, I really hope that managed to knock some sense into you, you jack ass." Rin said to the downed human.

"Rin." Tsukune exclaimed in surprise. But then his face adopted a frown as he looked at the half-blood. "Rin, look don't try and convince me to go back, cause I'm not going-" Tsukune didn't get to finish his sentence as Rin delivered a right hook to Tsukune's face. "OW! WILL YOU QUIT HITTING ME ALREADY RIN!?" Tsukune shouted.

"No I will not. You know Tsukune, I thought you were a pretty cool guy when I first met you. Now I find out you're no different than the jerks who made me and Moka feel like outcasts and toss us aside like we were nothing but garbage." Rin shot back at him, causing Tsukune to flinch at his words. "Tsukune listen, you and I are going back to the dorms, you're going to apologize to Moka, and then we are going to sit down and figure this out."

"Rin, weren't you listening to me. I'm a hum-"

I know that Tsukune and I don't care! Tsukune, you said on the bus that I looked like I could use a friend, right? Well you were right, because my friends and my brother all turned their backs on me, all because of what I am."

"What you are?"

"And Moka, she said she never had any. All because she was different and everyone all avoided her and mocked her for being different. By saying what you said back there, you are no different than them. Let me ask, did it ever occur to you that all Moka ever wanted was a friend, regardless of what or who they are?"

Tsukune took Rin's words into account and realized that Rin was right and what a horrible mistake he's made. In a way, he and Moka were alike, Tsukune never had that many friends and was basically in the same boat as Moka and Rin too. When he entered into high school, he thought it was the start of a new life, a chance to finally make some real friends. He made a couple and he ended up throwing it in their faces out of fear. "You're-you're right Rin. What I said back there, it wasn't right. I need to find Moka and apologize."

"Well then, lets get to the dorms, what do you say?" Rin asked extending his hand to Tsukune who accepted it with a smile. They were about to head back when suddenly-

AHHHHHHHHHHHH

"What the? That was Moka's voice" Tsukune said out loud. "She's in trouble, Rin, we have to help her."

"Well then what are we waiting for? Let's go save our friend." Tsukune nodded at Rin and the two took off in the direction of Moka's scream.

Moka ran into the forest to try and catch up with Tsukune and Rin, only to end up running into Saizo Komiya. She now found herself with her back against a tree, her body covered in cuts and bruises as well as saliva, compliments of Komiya, who had transformed into his monster form. He was almost double his original size and bony ridges were forming along his shoulders, chest and elbows. His skin also took a light brown color and also sporting claws, making him an orc.

Komiya then grabbed her wrists with his tongue and proceeded to lift her in the air. Moka was scared to death, she had heard of what Komiya had done to get sent to Yokai Academy and now she knew she was about to be his next victim. "Please, just let me go and I won't say a word." Komiya only laughed at her request.

"And miss out on the fun? Not a chance babe." He said getting closer to her. As she struggled to free herself from Saizo's grasp, Saizo continued to laugh.

"TSUKUNE, RIN HELP ME!" Moka yelled at the top of her lungs.

"Give it up babe, no one is coming to save you now."

"Wanna bet?"

Saizo heard the voice and turned towards it, only to have a large rock thrown into his face. Saizo growled in pain as he released Moka, who fell to the ground. She looked up and saw it was Tsukune and Rin. Rin then ran straight towards Saizo, jumped towards him with his legs extended, and kicked him straight in the face, sending him flying towards the nearby graveyard. Tsukune then went towards Moka and extended his hand to offer her help. "Are you alright Moka?" he asked.

She looked up at her savior, tears welling in her eyes and she launched herself into him, tackling him to the ground. "Tsukune." she mumbled. "I'm sorry. I'm so, so sorry. You said you didn't care that I was a vampire. Well, I don't care if you were a human, monster, or anywhere in between. You are still my friend, you both are. My precious friends, and that is all I ever truly wanted in this world." She proclaimed to the two boys, who proceeded to comfort the crying girl.

"Awwww, how sweet." They heard a voice in the graveyard. They then saw Saizo get up, looking more furious than ever. Tsukune put Moka behind him. "Moka, whatever you do, stay behind me." She nodded at his demand. "That was a nice hit, but now you are GOING TO PAY YOU WORMS." He roared at Tsukune and Rin and charged at them.

Saizo raised his fist towards them, which was caught by Rin, surprising the orc. "I thought I warned you what would happen if you ever came near us again Saizo. Well, here's your punishment." Rin then delivered a swift punch to Saizo's chest, knocking the wind out of him and causing him to stagger. Rin then took the opportunity to perform a round house kick to the orc's face, knocking him to the ground. "Moka, Tsukune, get somewhere safe, I'll handle this asshole."

"We're not going to leave you Rin." Tsukune replied.

"Just go, I'll be- ACK"

Before Rin could finish, Saizo regained his bearings and sucker punched Rin, causing him to fly into the adjacent forest. "Shouldn't have took your eyes off me twerp. Now then, where were we?" He turned to the human and vampiress.

Not taking any chances, Tsukune grabbed Moka's hand. "Come on Moka, let's get out of here!"

"But what about Rin?"

"RAHHHHHH" Rin came running out of the forest, jumped onto Saizo and wrapped his arms around his neck, choking him.

"GAH, GET OFF OF ME YOU LITTLE BUG!" Saizo shouted as he tried to rip Rin off of him, with little to no success.

"Guys, get going!"

"He seems to have things under control. Come on let's go!" With that, Tsukune took off in a sprint with Moka close in tow.

Saizo managed to get a hold of Rin and was now holding the half blood in front of him. "As much as I want to squish you like the little bug that you, nothing will put a bigger smile on my face than messing up that little fanged slut until she begs for more." He said to Rin before he threw him to the adjacent graveyard. With the half blood out of the way he took off after Moka and Tsukune. Rin looked up to see Saizo take off into a sprint.

"Dammit, I have to stop him before he hurts Tsukune and Moka. If only I had my sword."

"RIIIIIIN!" Rin heard an all too familiar voice behind and was shocked to see who it was.

Back to Tsukune and Moka, the two were still running through the forest outside the school. The small distraction Rin provided gave them a good head start, but neither knew how long it would last, so they made every moment count. "I'm really worried about Rin, Tsukune, we shouldn't have left him back there."

"Don't worry Moka, from what we've seen Rin do, I doubt an overblown muscle-head like Komiya will be too much for him to handle." Tsukune assured Moka, doing little to ease her mind. "Moka, don't worry, I bet Rin already dealt with that jerk."

"Guess again you little bug."

The two looked behind them and saw Saizo flying in the air towards them. Tsukune grabbed Moka and jumped out of the way. "Not bad for a bug." Tsukune and Moka looked to see Saizo towering over them with a wicked grin on his face and his tongue wiggling out of his mouth. "You and that worm from earlier caused me a lot of trouble, but I'm feeling generous today. Give me the girl and maybe I'll let you walk away." Saizo offered the human, who was repulsed by the offer.

"You think I would sacrifice Moka just to save my own skin, that will never happen you jerk. If you want Moka, you'll have to go through me first." Tsukune said bravely, despite the fact his knees were shaking.

'Tsukune.' Moka thought to herself, she knew Tsukune was scared, but for him to stand up for the way he did caused a warm feeling to stir in her chest.

"So you want to die defending her? Fine by me. Maybe I'll leave you alive to watch the show." With that he jumped towards the two again to try and crush Tsukune, who again grabbed Moka and jumped out of the way, this time down the side of a hill.

Tsukune and Moka rooled down the hill for what seemed like forever until they finally stopped on solid ground. When they looked up, they realized they were at the bus stop. Tsukune looked up to see Moka was on top of him and she was crying. "I'm sorry Tsukune. You and Rin are in danger because of me. I never wanted any of this to happen. All I ever wanted was friends and now the only two friends I ever made are hurt now. I'm sorry." She apologized to Tsukune, tears falling from her eyes and onto his face.

Tsukune hugged the crying girl, surprising her. "It's alright Moka, because Rin and I are the same. When I first met him, he looked like he could use a friend and I was more than happy to be one for him. Same thing with you, I couldn't care less if you and Rin were human, monster, or anywhere inbetween, you two are my friends."

Hearing this made the feeling in Moka's chest grow even further and produce more tears, only these tears were tears of happiness. 'Tsukune...'

"ROOOOOOAAAAAAR!" Saizo appeared before the two again, having jumped from the higher ground.

Tsukune brought himself back on his feet, helping Moka get back up as well. He then got in front of Moka, not realizing he accidentally pulled off Moka's Rosary. "Back off you creep! Like I said, if you want Moka, you have to go through me." At that moment, a flash of pink energy began radiating from behind Tsukune, surprising him and Saizo. Tsukune looked and realized Moka's rosary was in his hand.

"My rosary, it came off." Moka said surprised. Suddenly, she was engulfed in the pink energy and bats began to engulf her being until she was completely covered in them. After a few moments, the bats began to fall off her body until they were all gone. What emerged was Moka Akashiya, but completely changed. She had gained a few inches, her pink hair had become silver, her green eyes became red and slitted like a reptiles, and her feminine features became more curvy and defined.

The newly changed Moka looked towards Tsukune, who was shivering in her presence. "So, you are the who broke the seal and released me." She said in a much deeper and mature voice. Tsukune was speechless, he was afraid to say anything to her for fear of saying something wrong, which would cause her to harm him. And he wasn't the only one who was quaking in fear of the awakened vampiress.

"T-this power...there's no way. A legendary S-Class super monster. A Vampire!" He said with fear evident in his voice.

"So you're the reason I was woken up in the first place then." The silver haired vampire said in a bored tone.

"What the hell? What's wrong with me? I mean she's only staring at me but I can't stop shaking." Saizo said talking to himself, still shaking out of fear from the power the transformed Moka was pouring out. Moka on the other hand was either stretching her arms above her head or hopping around without a care, trying to get the starch out her joints from being asleep.

"No, this isn't right. Come on, pull it together, if you took down a vampire..." Saizo began to fantasize how his reputation would ultimately rise if he took down a vampire. That fantasy however would never come to fruition.

"Yaaawwwwwn...it's time for you to know your place." With that, Moka raised her right leg and struck Saizo's face, sending him flying into the steep hill. Thinking it's over, Moka then started walking over to Tsukune, until she heard Saizo get back up and charge at her.

"No way, this is not how I'm going down, not by a slut like you." Saizo shouted while running towards Moka with his fist raised. Just as Moka was about to deliver another kick, someone or something beat her to it.

BAAAAM

This time Saizo received another kick to the face, but it wasn't from Moka. When he regained his senses and his sight cleared, he saw Rin Okumura standing over him with a sword in his left hand and a mysterious black cat like creature on his shoulder. Even though his wounds from earlier had healed thanks to his healing factor, blood could still be seen around his mouth and his forehead, which looked like it was starting to dry up. "Attacking a lady when her back is turned, just when I thought you couldn't stoop any lower." Rin said with anger in his voice. Rin was on his feet, he was pissed, and he was looking for payback.

"You damn brat! Don't you know when to quit?" Saizo growled annoyed.

Rin looked towards Moka and was surprised to see he as she was now. He then looked to Tsukune who held Moka's rosary in his hands. "I'm sure there is a story in here somewhere, but for now I think we have a scumbag that needs to be taught a lesson." He said to the both of them.

"Indeed, and impeccable timing by the way. Even I have to admit that was a nice kick." Moka said complimenting Rin, who in turn just grinned.

"Thanks. You know, I think you've dirtied your hands with this asshole long enough. How about you sit back and let me finish this. After all, I owe this jackass for that sucker punch from earlier."

"Then by all means, he's yours." Moka replied gesturing to the orc.

Rin nodded his head and looked towards the cat creature. "Kuro, go hide somewhere. This will be over quickly."

"Okay Rin." Replied the cat, now known as Kuro. With that, the cat jumped from Rin's shoulder and ran towards the scarecrow.

"You think you can take me with that fancy butter knife? Ha, don't make me laugh. I already threw you around like a rag doll, who's to say it won't happen again?"

Rin's grin disappeared and his face turned serious. "Why don't I show you what this 'fancy butter knife' can do." He said bringing the sword to his face with his right hand gripping the handle.

SWOOOOOSH

At the moment Rin unsheathed his sword, he was enveloped in bright blue flames, shocking the three who were present. Saizo now looked like he was about to shit himself. "N-no way. Blue flames and this power. It can't be...the power of Satan."

"S-Satan?" Tsukune said confused.

"As in the god of demons?" Moka said just as surprised.

"I told you you would end up with a hell of a lot worse than a broken nose if you went near me or my friends again Komiya. Well, time to pay the piper." Rin said as he stuck his sword into the ground. "SATAN BOMB." At those words, a series of explosions occurred and the blasts trailed to where Saizo was standing.

KA-BOOOOOM

"AHHHHHHHHHHHHH!" Saizo screamed in agony and then fell backwards on the ground. He was badly burned, but he was sadly still alive, his pained groans evidence of that.

"I controlled myself this time, but next time I won't hold back Komiya." Rin warned the orc. He then sheathed his sword, causing his blue flames to dissipate. He then walked towards Tsukune and Moka. "So...What did I miss?" Rin asked with a goofy grin.

"I think a better question would be what the hell was that you did. Those blue flames, the only creature I know that can create such flames is Satan. What is your connection to him?" The transformed Moka inquired.

"Yeah Rin. Don't get me wrong, that was pretty amazing, but, what kind of power was that?" Tsukune asked.

"Welllllllll...It's a bit of a long story. How about I tell you guys back at the dorms." Tsukune and Moka agreed and the made their way back to the dorms. Kuro jumping on Rin's back as they started walking.

And cut right there. Next chapter Rin will explain his origins to Moka and Tsukune as well as how he ended up in Yokai Academy. He will also explain the fundamentals of being an exorcist to the two. I wonder how they will react when they find out the whole new tidbit of information. Find out next time in The Son of Satan in Yokai Academy chapter 2: The Half-Blood's Tale. PS: for all you Blue Exorcist fans, if Rin seems a little OOC, well when not only your friends but your only family turns your back on you, that can really change a person. If that's cool for some of you then kudos. If not, I don't know what to tell you. Anyway, thank you and see you next time.
