A/N: Before you ask, there is no NTR but there will a lot of plot twists including one big twist involving one unexpected character.

I will portray Ryo Asuka and Kuyo in a not great light because I despised them for their actions.

Also, don't spoil the twist.

Chapter 1- The Devilman in Yokai Academy

Akira was sitting in a bus, absolutely bored as hell.

He remembered this morning that his friend, Beatrice gave him a mission.

That mission is to pretend to be a student at Yokai Academy because of reasons but that damn bus driver is creepy to the teen. Akira looked up to see a tunnel as the bus drove closer and closer.

A brown hair teenage boy woke up from his sleep. He know that Moka Akashiya and the others will be worried. He got up from his bed, got his uniform on and exit his dorm room.

The outside was a bit cloudy this morning like it's going to rain.

"Odd?" The boy spoke until he noticed another boy in the exact same school uniform as a Yokai Academy student but he was just wearing the jacket but no shirt or tie, leaving him completely shirtless.

Maybe he could one of the delinquents?

He was about to approached the strange new student until there was a loud familiar voice.

"TSUKUNE!!!!"

Tsukune turned around to see Moka Akashiya running and hugging him. Right as she was close to him, a projectile made of ice was shot at the two, flying in-between them and hitting a tree, getting stuck in the progress.

"Mizore!?!" Tsukune Aono spoke as the purple hair snow fairy who is peeping behind a tree.

"Was that really necessary?" Moka asked Mizore who answered, "Yes… You were about to suck Tsukune's blood… again."

"Uhhhhh Excuse me!!" The shirtless male yelled out, the three stared at the new student who is already annoyed.

"OKAY!!!" The new student shouted who is close to lose his mind, "Where's Yokai Academy!!!"

That shout nearly surprised Tsukune Aono. Moka seems helpful to the new student as she guided him to Yokai Academy.

Akira knew that plan wouldn't work. He knew Beatrice's plan might have some flaws. When Akira saw the school exterior, he saw something that looked something out of a very old horror movie that may or may not be lost.

"Now all I need is the setting to be night with a full moon, a wolf howling, Vincent Price doing a voice over and I would feel like a character in a cheesy horror movie." Akira thought to himself. The interior seems a bit warmly designed for a haunted house. There are multiple students who are hurrying to get to class.

Akira sighed as he followed the pink haired girl and the boy, unaware that a certain blue haired Succubus was watching him.

Akira Fudo stared at the teacher who seems friendly looking. He noticed that guy with the pink haired girl from earlier. Curious, Akira got up and walked towards them which caused the pink haired girl to look at him weirdly like she is about to kick Akira's ass.

"Hey, hey!" Akira spoke, "I'm not hurting anybody but I wanted to know your names?"

"Oh. It's Moka Akashiya." Moka introduce herself to Akira. "And that's Tsukune Aono over there."

"Akira Fudo." Akira spoke, sheepishly as he ran a hand through his jet black mane. Then Kurumu Kurono jumped up and hugged Tsukune, her breasts almost buried Tsukune's face. However, Akira stood up and walked out of the classroom, slamming the door hard.

"That's weird?" Kurumu spoke as one student, a small and petite female with antelope horns and elf-like ears muttered softly, "Is he okay?"

"I can go check on him." Tsukune spoke as he got up and approached the door.

When Tsukune Aono stepped out with Kurumu and Moka behind him, he saw Akira Fudo standing in the hallway. His fingers were trembling as he was talking to himself.

"A-Amon... Don't you dare..." Akira muttered.

"What?" A dark voice spoke, "Listen boy, I nearly lose Nike to that Psycho Succubus Bitch then you almost lose Beatrice to Morrigan Aensland. I'm not risking losing to another Succubus."

"You ok-"

"Shut up!!!" Akira snarled, pinning Kurumu to a wall, silencing her. "You have no idea you're getting yourself into..."

Kurumu felt nervous and scared for her life. She had dealt with situations before but this is different.

Kurumu decides to one thing to get out of this situation.

She hoped her Succubus Charm will get her out of situation. It seems to work until...

"YOU'RE FUCKING DEAD!!!!!" Akira's voice became deeper as his eyes became a yellow color with no irises at all. But when he saw Moka, his eyes returned to normal and regret fill his body like a water balloon, ready to pop open. Then he ran off, gritting his teeth to not cry.

"AMON YOU IDIOT!!!!!!" Akira shouted to himself, sickening by what Amon almost made him do. He almost killed someone.

"What!?!" Amon spoke to Akira, "That Succubus is trying to-"

"Akira!" Tsukune's voice snapped Akira out of the arguement with Amon as he and Moka showed up. "Listen Tsukune, I felt very sorry for acting aggressive towards Kurumu but I feel..."

"Well, well, well..." A voice spoke as a familiar figure approached that made Tsukune Aono and Moka remember that event.

It was Saizo Komiya.

"Is this the new guy?" The burly student spoke, popping a fist. "Don't make me show my other self." Akira mutter under his breath, his voice becoming deeper.

"What's that?" Saizo spoke, taunting Akira who speak louder that sounds similar to a growl, "Don't make me show MY OTHER SELF!!!!!"

Then Saizo Komiya transformed into his orc form, his tongue lashing out. "WELL BRING IT ON-"

Saizo was unable to finish as Akira's body changed, he was becoming taller and muscular but something is wrong. His skin is now a bluish-gray, black fur covered his legs and he has clawed feet and fingers. His head was covered in hair that sprouts bat like wings off the sides and horns that look like antennas near the top and formed a widow's peak with a red forehead. His back also sprouted large crimson red wings that look like it belongs to a dragon. He also had a long furry tail that hit the ground like a whip.

"You can call me Devilman!!!" Devilman snarled in his deep voice as he grabbed Saizo by his ankle.

Bite Size Dictionary:

Devilman are the result of an unholy fusion of a human and a demon. The Devilman will look like their demonic counterpart and will have their powers.

Then he threw Saizo against the ground, leaving giant sized holes in the ground as the male student struggled. Though he didn't count, Devilman think he had thrown Saizo Komiya like 15 times.

When Devilman was done throwing him, he stared at the orc who is now stuck in the ground, dazed and bloody.

"Puny Orc..." Devilman snarled, exposing his sharp teeth, especially his fangs. Saizo let out a whimper as Moka and Tsukune were staring in shock. "I feel like it always happen." Devilman spoke, exhaling through the nose as steam literally exited his nostrils. "It's either they're easy to kill or a bunch of fucking cowards and run to the hills."

"Well, Moka is not a coward." Tsukune retaliated calmly, "Well, it's her Inner self you got to worry."

"Well, just do it." Devilman spoke, trying to sounding nice to Tsukune Aono.

Then Tsukune pulled the cross from Moka's choker which caused a bright light to glow. Devilman felt that gut feeling rising from the bowels of Hell. He wondered if using the word "coward" is a bad idea.

The sky suddenly became a purplish red color as a swarm of bats surrounded Moka Akashiya as Devilman was slowly backing up. "I got a bad feeling about this." He muttered to himself.

Then the bats flew off, revealing Moka's Inner Form. No longer an innocent looking lass, Moka now looked like a femme fatale. Her body is busty and curvy for a girl her age, her hair is a silver color with her eyes a blood red. The innocent personage is gone, replaced by a sadistic nature.

"So, you're Devilman?" Inner Moka spoke, "I believe it's the first time someone beaten Saizo Komiya that wasn't me."

Devilman knew that Beatrice will lose her mind but he did remember that one of Beatrice's trainers was Carla Cromwell. Then Inner Moka's words snapped Devilman back to reality. "So?"

"Well." Devilman spoke, "I want to see how strong you are?"

Innee Moka stared at Devilman then sighed heavily.

Then she violently slammed her foot against Devilman's chest hard as the demon was slammed against multiple trees before hitting one large tree. It was a miracle that the tree didn't break under Devilman's large frame. When the dust clear, Devilman was on the ground with a large bruise on his chest where it's located on his ribcage. Blood ran out of his mouth and dripped past his lips.

Tsukune stared in shock as he stared at Devilman who stood up weakly, carefully covering his bruised ribcage. He know that he might need help due to the injury but to the shock of Tsukune Aono and Inner Moka, Devilman reverted back as Akira Fudo and the bruise was gone but he had blood dripping from his mouth as spat a glob of red on the ground. "You okay?" Inner Moka asked Akira who is getting up. "I'm fine... I mean that kick is strong." Akira spoke, cringing as he gripped his side of his chest.

As Inner Moka and Tsukune helped Akira up, the silver haired female vampire looked at Tsukune.

"Are they ready to see him?" She asked him as Tsukune thought and thought about it.

"Okay Akira, you're ready?" Tsukune asked Akira while Ginei looked at Tsukune Aono, confused why he and the others are here for.

Then Akira stepped out of his hiding location, his demonic form exposed to everyone. Ginei was surprised by the sight.

"So, that's Devilman?" The werewolf asked Tsukune who replied, "Yes but I swear that I heard a deep voice when I saw him in the hallway and-."

"Are you talking about me?" The deep voice came back.

"Who said that?" Tsukune Aono asked, frightened by that voice as he looked at Devilman who is strangely changing.

"ME!!!"

Then, Devilman's body began to change, he became a large red-skinned demon with black fur covering his lower body and around the neck area especially with his long hair. He had a barreled chest and large muscles.

Huge Leathery wings grew out of his back, a pair of smaller but noticeably tightened veins wings come out of the sides of his head and horns that look like antennas that popped out of the top of his head. He had also yellow eyes with no irises as well as razor sharp teeth and claws.

Ginei Morioka screamed loudly, the werewolf gripping his hair. Mizore's eyes were wide in shock, Tsukune Aono was surprised but kept a brave face while Moka hold her hand in a self defense pose, Ruby was holding Yukari in front of her as some kind of sacrificial offering to some deity, the latter seems ready to fangirl over Amon like some kid meeting their favorite actor/wrestler. Kurumu Kurono is in some kind of trance upon seeing the red skinned demon.

"You okay?" Amon spoke, now concerned about the Succubus. Then Kurumu coughed into her hand, her face was now completely red.

"It's because you seems big so I guess you had a big.. you know."

Immediately, Amon's mind was full of, "OH MY GOD!!!!! FIRST BEATRICE, NOW HER!!!!"

"You okay?" Tsukune asked the red skinned demon who calmed down. "Sorry for acting aggressive to your friend." Amon spoke softly which is uncharacteristic for a demon who is called "Demon Lord of War" and "Beast of Hell" as he changed back as Akira Fudo.

Peeking outside was someone who looked like Moka but with short hair and blue eyes who is staring in shock.
