1 Sir Knight 

- Cheery and loud, this teacher, although he isn't that flashy in his ability, is one of the top supports because of his ability to copy the hardness of objects.

The downside to it though, is that the weight of the copied object would also be felt by him. Meaning, if he copied the hardness of diamond and made his body bulletproof, he'll weigh as much as a human sized diamond statue.

Due to this, he has worked his body and strengthened it to be strong enough to keep up with the weight.

He always wears a platinum plate armor that he can easily copies the hardness to. He carries a single diamond in his gauntlet, to prevent enemies from ever scratching him through.

During the rescue operation of Ai, a villain managed to shoot through his armor, he was able to transform the targeted part of the bullet and made it as hard as diamond though before it could shoot through.

Once he takes off his armor, he has the speed and strength powerful enough to create cracks on thick walls due to his constant training to carry the weight of the stuff he copies.

He used to work as a support in the frontlines and acted as a shield against opponents.

Really tall. He is about 30-40ish

2 Kana Asami

-Most of the time sarcastic and mocking, Kana, as the principal of the academy, boasts a simple but very powerful ability, Rewrite.

Her ability allows her to erase a target's certain memories.

She could either tamper with the target's memories by locating a certain memory she wants to erase or just set a certain amount of time the memory she erases.

Basically, just like when you clean your browsing history, Kana's ability, when not focused entirely, can delete the browsing history (memory) of a person for the past hour, day, week and much more.

She could not do so unless the target's mind is weak though, that is why, she could usually only use her ability when the target is unconscious, weak, exhausted, injured or asleep.

She could see or notice if a target's memory has already been tampered by her since a day ago.

Her eye acts like the gun that shoots out the bullet to erase the memory of target or target's.

(I haven't really thought much about how incidents in every place make it so that every civilian forget about the villains or the saviors who fought that time. I thought about making her ability possible as long as there's a recording of her, but that's make it easy for villains to use.

I also thought about her ability working even through just Skype, or any camming application whatsoever. Whatever it is, I haven't thought of it yet.

I thought about making other saviors or supports that have the memory tampering ability, but for some certain circumstances, I might not be able to do that)

She used to work as a strong support.

And met the love of her life during those times.

Age is about 20-30ish

3 Net

I haven't shown him much again, but he's one of the teachers I first introduced.

I kind of based his clothes off Kamui woods except the blue and yellow colors are inverted.

His ability allows him to create huge nets just like from his name.

You might be reading a stolen copy. Visit Royal Road for the authentic version.

He's a young teacher that hasn't really faced the battlefield yet.

Age is about 20-29ish 

Youngest teacher btw

4 States

So she, is a very interesting character.

The ability I gave her, I never talked about it before, but I think it's really cool.

She has the ability to change the state of an object.

For example, she could turn a wall into liquid and gas in a certain amount of time according to it's size and thickness.

She specializes in turning things into liquid, and thus she most of the time, keeps her body in the liquid state.

Once she turns something into one of the states (gas, liquid or solid, she turns into that as well)

For example, if she turns a rock liquid, she turns into her liquid form, if she turns it back solid, she'll turn human again, and if she turn it into gas, she'll be just air.

Unlike, Mizumi Hana though, she can't use her ability to the living besides herself.

She always wears a surfing suit like thing that can be worn by his liquid and gaseous state.

Her gaseous state is sort of hard to manage though, since a strong gust of wind could split her into pieces and she would need to combine herself up before transforming into her solid form again.

She used to be a tomboyish lifeguard a long time ago.

Age is about 20-30ish

5 Mind Whisperer

Old plain looking man, that used to be a real playboy in his young years due to his ability to read minds.

He can not only read the minds of the people in a certain radius near him, but talk to them directly through the their minds.

He used to sweet talk girls and fool people until he met someone who stood up to him (his wife)

He became more docile due to her and became a support to help her.

He joined a rescue team and acted as the information goer to those guys.

He still lives with his wife and plans to retire a few years from now.

Age is about 50-70ish

6 Sakura

The female teacher who always wears a kimono and a noh mask.

She's beautiful and pale as heck. Has long white (pinkish) hair and speaks politely.

Ability is called bloom and petals.

She can create and manipulate cherry blossoms that has a certain soothing aroma that can regenerate the energy of the ones who smell it.

Her cherry blossoms can also act as blades, but aren't really that much suited for combat since they're small, although they can be used in large numbers.

She's about 20-29ish be single

7Strategiser

The pineapple haired (not an actual pineapple but the sort of large bun hairstyle of females) woman who usually wears business suits.

She has a sort of bossy and hot tempered personality, and is sort of tsundere as well.

Her ability is called calculation.

She can formulate certain plans that calculate the moves of the opponents and stuff like wind direction, projectile aiming and strategy planning whatever.

She's just a common teacher, but she's very close to X-tinct.

She fought with him during a certain battle and he believed in him although she was sort of bossy.

8 Elasticity

The old serious lanky geezer that used to be quirky and energetic like net. 

Time made him grow into a serious, strict-mannered man that wanted to watch over the growth of the youth.

His ability allows him to act like a rubber bodied man, that can shift his body into the shape of varying objects. He has a limit to his stretching though.

His skin can become bouncy and thick if he wants it too, which makes him possibly, a great cushion for spiky attackers 

He's about 50-60 years of age.

9 X-tinct

Wears furcoats all the time because Arata (Akira and Akio's father) told him it was cool.

He used to have black hair and eyes until he awakened his ability.

His ability, annihilation, allows him to create a white, destructive light that can be used in a certain amount of ways.

His first name was revealed to be Lane.

He's in his 30s.

10 Akiko Ishikawa

Her ability is gust.

Basically, she could release a gust of wind through her torso and back.

Like Megumi, it could act like a boost in her strength and speed.

Not lots have been known about her besides her love for her family.

11 Kotone Kawai

Koka's hot mother. Used to be a poor woman that was abused by his husband's family.

Her husband sided with his family though and threw her aside.

She wanted to take Koka with her when she left, but she was just a poor woman with no capability of raising her then.

She was able to work hard and become successful years after, she kept writing letters to her daughter (Koka never received any due to her husband)

She isn't really the type who loves using technology so she didn't really know she could've just spoke to her through social media.

Her ability's currently unknown.

Villains:

12 (Zombie faced guy I never named)

He has sharp teeth like a shark and a face sewed like BlackJack

His ability is shadow manipulation.

He could manipulate shadows into his dolls he could control like a person.

His shadow merge ability, allows him to merge with his shadow, to create a stronger form of himself.

He's able to lash out stretching shadow arms that can be turned into shadow spikes and can be pieced together as a single large spike.

Since it's just shadows, he can create multiple arms, but more so would cost his energy lots.

13 (Frankenstein like villain)

The villain from the last chapter, has a frankenstein like look but with piercings all over his body.

His ability allows him to consume metal, with his hard teeth.

He can then use the metal he consumes to turn his limbs into a metal weapon.

Due to him losing intelligence, the only thing he could create are spikes.
