Welcome back to another new chapter.

Now we are at chapter 10, at this point, I will mostly abandon my story to write a new one. But I guess I will continue it a bit more then come back to other stories to continue it.

Now the plot is finally happening, I will let you guys guess it, I will just write, 1 month for Angelia to prepare is more than enough to give her enough power over the rebellious devil.

And sorry guys, I'm kinda sick (I'm not sure it's because of COVID-19 or not, I always stay at home and didn't go out for a month already) I'm trying my best to write this chapter on my phone, yes on the fucking phone and it's a pain in my ass.

Chapter 10: a teacher's duty


(Angelia's POV) {after school}

And the first day of school pass just like that, nothing special happened. Except during lunchtime, I saw Koneko and Kiba going together to a hidden spot and teleport aways, I guess during the early time, a lot of strays devil still hiding in the city then.

During the lesson, I usually use observe the student make sure I didn't miss any sacred gear holder, luckily, only Issei is a sacred gear holder. So I will pay some attention to Issei, I don't wanna let my students die before the year-end.

"Hehe, look at Murayama's body..." "Yeah, look at Katase too, she's hot"

Huh? That came from the Kendo club's direction and those lewd noises... Who else it can be other than the perverted trio? They must be sneaking into the changing room again. As a teacher, I must teach them a lesson, right?

Sneakily approach them and give them a scare, that is the plan.

"We must memorize this, this is the first time in the year!" Issei, my dear protagonist, as your teacher, I will give you a good impression so you will fear me, even after you have the power of your sacred gear.

"Yes, you bad boys should memorize this since this will be your worst detention and the worst nightmare you will ever have."

"EHHH!?" Hehe, as expected

"No Eh and Ah, stay with me at school until 7 pm, I will give you some traumatic experience." Now I have some good methods in my head, I will enjoy hearing the pain of those perverts, hehe, being sadistic is bad but it enjoyable.

"What do you mean by traumatic experience sensei? Please tell us you're joking!"

"No joke intact, come to my office now, or else I will cut off your penis and send you to a transgender place." Seeing them holding their balls like that, I know my plan has worked out well, now to the next step, changing their attitude to women in general, they should respect women more, I believe everyone can change with the correct method. Besides, a teacher has to help students get better after all.

{Time skip... since I don't wanna write about the mind deforming part, its too complicated for me}

"Ehem, and that is the end of our lovely detention class today, I will see you tomorrow if you still dare to disrespect a woman." The lesson went well I guess, it was just some storytelling and some mental help, I'm an all-rounder teacher, after all, I know many methods to help students in a lot of ways.

"Now you can go home, or stay a little bit longer, there will be a surprise for you if you want to stay, I'm never stingy with my students" If you dare to stay a bit longer, I will bring you to meet the stray devil my dears, then turn you into a martial artist if you want.

"No, thank you sensei, we will go now!" ... Am I that scary? my students in the past life also run away like after the detention ended. Well, I guess it doesn't matter anymore, now I need to spy on the naughty devils.

Walking out of my office, I locked the door then leave the school, everything seem normal.

But not for me, my wings are ready to take off, I can't let those naughty devils running outside and battle alone, let this hardworking teacher help them to set a small goal: to stop this villainous fallen angel from destroying the entire world, I don't think it will be possible but I can try ruining the balance of the world.

They should be around that area, I can see some abnormal heat signals from there. Maybe it was caused by Rias's power of destruction, better get going.


(3rd POV)

BOOM*

A red beam explodes when it touches the stray devil, making the stray explode into multiple pieces

"I think we have finished it, let report this when we get back, the stray devil Taki has been eliminated, let's go back," then Rias tell Akeno to draw the teleport circle, but before the circle were finished, a string made of black goo caught Koneko while she isn't paying attention.

"Hehehe, look at who I got, a petty devil who can't even defend itself, I will eat you, then all of your friends" Not letting the chance go, the stray devil open its mouth filled with sharp teeth, directly bite Koneko's shoulder.

But fortunately, as a Rock, Koneko possess great defence so the teeth only leave some medium wound. "So you are a Rock huh? Not a problem at all, if 1 didn't work then I will do it again!" The stray opens its mouth again and if it successfully bites Koneko again, her entire shoulder would be bitten off. Of course, Rias and Akeno didn't stay still, they chant their magic, hoping to recuse Koneko in time.

BANG*

[Headshot!] x4 damage

A loud lighting sound suddenly passes through Koneko's shoulder, after the that the stray's head disappears without a trace left, leaving the body falling lifelessly. Koneko stood there, confused about what just happen, her friend is as confused as she too.

Not letting everyone regain their senses, Angelia appear behind the dazed Koneko, she grabbed Nekomata's waist and look at Koneko with a fake smile, behind her smile is a bit of nervousness and a bit of... lust? it understandable since Koneko is missing some pieces of clothes.

Angelia restrains herself and whispers into Koneko's ear with a mysterious tone: "Little cat, why are you so careless? If you get injured that badly, your sister may get mad" When Angelia mentions the words sister and cat, Koneko immediately snap out and turn her gaze to the voice.

Her gaze met with a beautiful face yet it give her an uneasy feeling, the pair of terrifying red eyes seem to stare at her soul. Then she notices the black wings behind the woman, '8 wings!' her body shake in fear, but it lessened a little since she can't feel any hostility from another party.

"Who are you? And why are you helping me?" Koneko takes the inactive to ask.

"oh, I'm just a fallen angel that love human, I don't have any ill intention, to humans at least."

Outside, Angelia is using her skills to act as a villain but inside her head is a bunch of messy thoughts.

'Oh god this isn't what I wanted to do, why did I use the railgun to save Koneko? She will be fine after a few days.'

'Does the overprotective trait that bad?'

'Sure enough, I'm not a good actor, but this is too bad!'

"How did you know about-" Angelia place her finger on Koneko's mouth, stopping the girl from talking "shh, little cat, you shouldn't talk here, your life is in my hand, and your sister won't be happy if you die here. Shiro and Kuro, I wonder when both of you can get along again?..." Koneko's nervousness raise as Angelia continue to talk about her relationship with her sister.

BOOM*

A red beam passes through Koneko and hit Angelia, even though Angelia's immune to magic, she pretends to get hit and fall back. "Oh my, I expected the crimson princess, the younger sister of the Satan is stronger than this, look like I overestimated you too much."

"I don't know who you are but you dare to lay a finger on my peerage then you won't have a good time with me."

"Hah? I won't have a good time? The crimson princess is giving me a threat, so scary, what can a petty devil like you do? You haven't mastered the art of destruction magic like your brother yet, even if you have mastered it you are still not my opponent"

Angelia waves her hand with a disdain smile on her face, "but fine, I don't hold a grudge against the youngling, so take your friend away, you're not my primary target."

Kiba quickly rushes up and carry Koneko back to the group, Angelia still standing there and watch the group preparing to escape 'Well, I guess the younger generation has become more and more careless now, dare to draw a teleportation circle in front of 8 wings fallen angel like me? Lucky for them I'm not a real bad guy or else they will be dead on the spot'

"Well well, look like the princess is in a hurry, I won't interrupt your time anymore. Just remember, the fragile balance of this world gonna fall soon, and the person who causes it is me, fallen angel Aisha"

Before the devils leave, Angelia decide to leave a"Kokabiel want war but I desire the fall of the world, remember that young devils" Then she take off into the night


(Angelia POV) {at home}

"Welcome home my dear villain, how is our first debut going?" "terrible wrong, I used my acting skill and said that we will ruin the balance of this world, which is particularly impossible for our level!"

Yes, things go very wrong! My forgotten trait is 'overprotective' activated and I don't even know why! Now because of it, my original plan has been ruined, what to do now? How can I save the situation?

"Hey... Why don't we do as you said? ruining the balance of this world? We have the tools to do it." Tools huh? "You mean the system?"

"Yes, the system provided by Raifu-sama give us a lot of equipment, like the memory alters scroll, if we use it on an important person, the balance of the world can be overthrown!"

... Yeah, that sound legal, maybe I can try that out with an important person, but who should I use it on? The great Red and Ophis are out of the range. Someone whose influence is really large...

Maybe... a pure angel is enough to overthrow the balance? An angel who is important enough for heaven takes action when she becomes a fallen? Perhaps the perfect candidate is her... "Hey, Do you think getting Gabriel's memory altered is worth the risk?"

"...That is ridiculous and I love it! We are the gamers, we should make things as big as possible. Imagine making Gabriel into our servant or slave, the heaven and will go after us, and if we do it in the right way, the war between fallen and angel will happen, a bit like Kokabiel's plan but much more evil I think."

"Yeah, that sound possible, but the problem is we need to attack at the leader's meeting to get Gabriel, the other method to get to heaven won't work for us since we can't use magic."

"Yeah, you're right... But I think is it possible to use the halo of madness to control a person's mind right? We will store up soul energy enough for some days than controls a weak person at the meeting and make a perfect mole inside them without them knowing!"

New plan accepted, now I need to build up a good relationship with Rias's peerage, in some way as a human."


{The next day, during the break time} (3rd POV)

On the rooftop of the school building where most people didn't go there much, Koneko is holding a candy box and eating candy peacefully.

From behind, Angelia climbed up and sit beside Koneko without the girl knowing.

Seeing Koneko hasn't noticed her presence yet, Angelia decide to start the talk "My student, eating too much sweat won't be good for you" Koneko was startled by Angelia's voice, she turned around and found Angelia smiling warmly beside her.

'When did sensei get behind me? I didn't notice her presence until now' Koneko thought for a moment and decide to stay on guard with Angelia.

Angelia quickly snatch the candy box from Koneko's grasp in a second then look at the stunned Koneko "As I said, eating too much sweat isn't good for your health, I will temporary keep this, I will give you some candy per day only. if I see you buy such an absurd amount of candy again, I will take it all!"

'She can even take the box from my hand so easily' Koneko become even more surprised at her teacher's ability, but her thought easily goes away and her attention goes back to her candy.

Koneko look at her candy box in Angelia's hand and try to reach it "give it back to my sensei, my health is still good with some candy, please give it back to me." Koneko begged

"No is no, as a good teacher, I care about my student's health... How about this, if you can get a perfect score in the exam, just in 1 subject, I will give you back this candy and even give you more candy." Angelia suggested

"No, I will never get a perfect score in school! Please give me back my candies Angelia-sensei." Koneko eyes have become slightly teary as she keeps trying to reach for her candy in Angelia's hand helplessly.

"...Then how about this? You can go to my house, I can help you to study, if you want you can also bring a friend with you, I will treat you some candy if you do."

Koneko's lit up a bit when she heard about candy but she hesitate to go to her teacher's house to study. After some consideration, Koneko eventually agree to go to Angelia house to study.

"That is great, I didn't expect you to agree despite being a glutton. Meet me at the school's gate after school and I will lead you to my house if you have time... Nevermind that, I will give you my address, you can seek me for help if you want."

"Thank you Angelia-sensei, can I have my candy box back now please?" Angelia look at Koneko with a bit of hesitation, in the end, Koneko got her candy back.

Before leaving, Angelia leaves a reminder "remember to study well, find me if you have any problems, I will take all of your candy again if you dare to broke your promise." Then she rushes downstairs in a flash

'She is so fast... Does sensei involved in the supernatural world too?' Koneko noted to herself to report this to Buchou after school.

{KING CRIMSON USED TIME ERASURE}

{at Kendo club}

"Are you sure there is no one here?" Matsuda nervously asked, from the last incident, they have become more careful at peaking, the 'lesson' given by Angelia has planted a little bit of trauma inside them

"Yes, I have double-checked the area, there is no one here," Issei confirmed

"That is great, now back to business." but unfortunately for them, before they can get their eyes on their 'heaven', a devil appears behind them, along with a sweet voice.

"Ara, look who do we have here? the naughty boys didn't learn their lesson at all."

*Gulp*

The pervert trio froze on the spots, they slowly turn their head to see their devilish teacher standing behind with a smile on her face, behind that smile isn't something they want to experience again.

"So~ again?" to answer Angelia's question, the trio shouted quickly"No no, thank you for your time sensei, we will leave now." The pervert trio immediately leaves the scene. The Kendo club girls notice something happening outside and go outside to see, they manage to catch a glance at the fleeing pervert trio and Angelia-sensei looking happy at the sight.

Katase take the lead and asked Angelia "Uhm sensei, what is going on here? Why are they... running away?"

"Oh them? I just caught them doing something inappropriate so I just chase them away. Hope I didn't disturb your changing time."

+30 affection with Katase (For helping them)

+30 affection with Murayama (for helping them)

+30 affection with ...

...

The Kendo group immediately understand what is the inappropriate thing the trio did so they all thank their sensei for that. Angelia stands there receiving thanks from the Kendo club as she immerges in thought.

Before the club get back inside, Angelia decides to ask them "... Hey girls, if you don't mind, can I go spar with you a little?"

"Uhh, can I ask you why sensei?" Katase asked

"Well... I have practised Kendo and several martial arts beforehand, but they kinda get rusty as time pass so I want to sharpen it up."

"I can understand Sensei, you can come with us, we lack a mentor too so if you want to you can become one and guide us."

"I don't think I'm suitable to become a Kendo teacher but I will try." then Angelia walking into Kendo's club room.


{On the stage}

Angelia decided to keep her clothes and put some guards on, even she doesn't need to do that. Taking a good stance, she raises the wooden sword with just 1 hand.

"Come here and don't hold back Katase, if not you will lose tragically. Do not underestimate your opponent no matter what."

"Hai sensei!" Katase didn't ignore Angelia's words at all since her opponent is an experienced Kendo practitioner.

"Start!" Murayama as a referee gives the signal for them to start. Katase wastes no time and charges at Angelia, the other just stand there with her Shinai in front.

Bang*

[You have blocked the attack]

The Shinais crash at others, but it seems Katase's hands are trembling a bit. "Your strength is good to consider your age but your stance is lacking and the speed is still slow," Angelia commented.

"By the way, when your opponents have blocked your strike, prepare to get a counter-attack from them," Katase's eyes widen, she immediately jumps back but it didn't work quite well. When she look up, Angelia's Shinai is in front of her, Katase raised her sword to block it by instinct alone, before she realize, the impact already happened.

BANG*

thud*

The Shinai in Katase's hands fly off her hands and land on the floor, Katase herself striped and land on her butt, her hands were trembling uncontrollably. Seeing her student's condition, Angelia helped Katase to get up and carry her down.

"Sen... sensei, how did you do that?" Murayama asked.

"Do what?"

"The speed and strength you display just now are so amazing, my hand now is still trembling because of the impact, how did you do it sensei?" Katase added

"Oh, you mean that? That is the result of practising multiple martial arts, it helps my body become more flexible and my hand's force has increased as well. My speed comes from running exercise, I can keep that speed for 5 hours at most."

"Really? That doesn't seem possible for a woman to do that right? I mean our natural physic is already bad."

Angelia look thoughtful for a moment, the Kendo girls are patiently waiting for her teacher's answer, they also want to become strong like their respected teacher.

After good fighting in her head, Angelia decided what she would do. "I will give you my address, you can go to my house and seek help, remember not to tell anyone else, a secret between girls okay?"

+20 affection with Katase (For helping them)

+20 affection with Murayama (for helping them)

"I understand sensei, thank you for your help." For 'unknown' reason, a blush appears on both Murayama and Katase's faces but it was ignored by Angelia since she is busying taking off the gears. After that, she continues to give some guidance to the other Kendo member then return home at night.


(Angelia's POV)

When I got home I immediately throw myself on my bed, and think, what I'm thinking about? I intended to act as a sword trainer of the two girls and lead them to the supernature world, they will become one of the witnesses of my betrayal.

But who knows when they will come here, I need some advice from my beloved brother and sister

[Cain]: I thought so too, but I can't do anything about it. Ugh, that thing already happened and I don't wanna talk about it anymore.

[Angelia]: Sure, and I just remember I have something to trade with you this time.

[Cain]: Oh, what a coincidence, I got something to trade too.

[Angelia]: That's nice, I got an epic skill I can't use here and some dragon bones, do you want dragon bones?

[Cain]: I got a good sword from Naruto verse here, to make it fair I will put another thing here, dragon bones are useful for me.

[Angelia]: Then let trades

That is the end of this chapter

Sorry for the late update, my body is feeling unwell these days so I can't write for some time.

Because of my body's condition, I will delay my story for quite some time, sorry for making you guys wait, I will write more when I get better. I hope this shit isn't covid or else I'm going insane.

Anyways, please review about this chapter, it kinda hard for me to write about detailed things
