My Hero Academia After

Name: Shorotani Neko
A student of class 1-A.
Quirk: Cat. Has all the abilities of a cat. Appearance changes include a tail and ears. At will, she can completely transform into a cat; she is indistinguishable from a normal cat, but cannot speak in this form.
She's very brazen and daring to everyone except her elders. She's not shy about invading people's personal space, and sometimes she'll deliberately do or say something ambiguous and then pretend she never did anything at all and that her words were only intended to convey one meaning.

The world from the anime My Hero Academia, after the events of the anime.

Name: Takado Datenshi
Nickname: Fallen Sun
Sain Kikyō's second-in-command. He is the older cousin of Takado Tenshi and Takado Akumi.
The quirk "Half-Angel Half-Demon." One half of the body is demonic (demon wing, horn, and tail), the other half is angelic (angel wing, half halo).
He's a mysterious character. He's completely subservient to his boss, but secretly wants to betray him. He's a hero to his brother and sister.

Name: Sain Kikyou
Nickname: Time
The main villain (but no one knows about him except high-ranking heroes). Father of Sain Jikan and Sain Kopiar, but these two don't even know their father by sight.
His quirk allows him to travel back in time one day after death. The return occurs at 12:00 PM, and when the next day reaches 12:00 PM, the checkpoint "moves to that point." Because of this ability, he cannot die. The moment of return appears as a sudden jerk, which can only happen at 12:00 PM.
The character follows the example of "All for One", as Kikyou is his successor in the criminal world.

Name: Shigeo Muraki
A student of class 1-A.
Quirk: "Pocket Dimension." Can create portals to his pocket dimension, 27 cubic meters in volume. Only non-living objects can enter the portal. All properties of the object are frozen at the point in time it was inserted, meaning food won't spoil, and any object entering at speed will exit at the same speed.
He has an unusual personality. Muraki believes that nothing can be accomplished without his power. He gets angry if someone succeeds without his help, angry because he's afraid his ability is useless.

Name: Kushinzo Anken
A student of class 1-A.
The quirk allows the user to alter the properties of any object they touch. The object must not be too large, must not have a complex shape, and must not be composed of more than three materials. Most importantly, the object must not be alive.
Anken's character is complex. He treats everyone differently and behaves differently with everyone, as if constantly putting on a new mask. In private, he's heartbroken and emotionless. His greatest fear is hurting someone.

The name is Shiuroku Yumin
A student of class 1-A.
His quirk is "Sleeping Eyes." Anyone who looks into Yumin's eyes instantly falls asleep. His eyes are completely black, and Yumin himself is blind, so he wears a black eyepatch just to prevent anyone from accidentally falling asleep while looking into his eyes. In one-on-one combat, he removes the eyepatch, forcing the enemy to fight in a daze to avoid falling asleep from looking into his eyes. This is one of the reasons he dislikes teamwork.
He tries not to show weakness, always remaining cheerful and smiling. He doesn't rely on others; he does everything himself. His perpetual joy and smile are almost believable; they seem genuine, although they are often fake.

Name: Ekitai Karada
A student of class 1-A.
Semi-liquid body quirk. At any time, she can turn her body into liquid (just her body and nothing else) for a short time, after which she can easily return to normal.
She's shy and embarrassed by her Quirk because it doesn't allow her to liquefy her clothes, meaning she needs new clothes when she returns to her normal form. Therefore, her hero costume was made from fabric infused with her DNA, so it would also liquefy and return to normal when Karada did.

Name: Hankuo Kyushu
A student of class 1-A.
A Quirk that absorbs and replicates sound. She can absorb sound waves within a small radius at will, then create the absorbed sound at a visible point. After each sound projection, the projected sound is erased from the "Gallery of Absorbed Sounds." It's impossible to absorb sounds indefinitely, as each sound requires Kyushu's actual memory.
He's quiet and loves listening to music. For him, the whole world is just a piece of music. He's not interested in other people, but he promised himself to be a hero, and he wants to be one.

Name: Takado Akumi
A student of class 1-A. Sister of Takado Tenshi.
Quirk "Demon." Has wings, horns, and a tail. Can do anything a demon can.
Her personality, surprisingly, is the opposite of her brother's. She's a real angel. She's kind and wants to help everyone. She jokingly despises her brother, but she really loves him very much.

Name: Takado Tenshi
A student in Class 1-A. He is the brother of Takado Akumi.
Quirk "Angel." Has wings and a halo (instead of flying above the head, the halo rests on the head). He can fly and is physically stronger than a human.
He has a vile personality. He only wants to be a hero for show and to use his powers for destruction. He's like a demon. He hates many, but he'll kill anyone for his sister.

Name: Renji Tachibana
A student of class 1-A.
His quirk allows him to absorb all kinetic energy that passes through his body and convert it into his own power. He still receives piercing and cutting injuries. He is weak against psychic attacks. He cannot absorb elemental energy (fire, ice, etc.).
He's self-confident, often takes risks, and enjoys being praised. He thinks he's practically immortal, though that's far from true.

Name: Hikaru Sakkaku
A student of class 1-A.
Quirk: Illusion Creation. In sunlight, she can create any visual images and objects that are indistinguishable from reality. She cannot create taste, sound, or smell.
Personality: Hikaru is a perfectionist and selfish in a good way. She doesn't suck up, but she sincerely believes she must be the best to live up to the memory of All Might. She is demanding of herself and others. Deep down, she fears that her Quirk is too "pretty" and impractical against brute force, so she fiercely strives to prove otherwise.

Name: Hikaru Akane
A student of class 1-A. Daughter of Fumikage Tokoyami.
Quirk: She can create absolutely anything tangible from shadows. For her, every shadow is a battery of shadow energy.
I have a playful personality and I really like to pick on any little thing in a conversation, but only as a joke, and I'm a little sarcastic.

Name: Momiko Tehnagia
A student of class 1-A.
A telekinesis-type quirk. What's unique about this quirk is that it can only move tools and finished devices.
She has a remarkable personality. She loves to build any kind of device, especially gadgets for heroes, and even more so for herself. She's cheerful, easily captivated by anything, fearless, and unashamed. It seems like she should be in engineering, but more than tinkering, she loves being a hero to others.

Name: Hagakure of Chaos
Class 1-A student. Daughter of Hagakure Toru.
This quirk allows one to become invisible and/or intangible at will. This allows one to be unnoticeable and/or pass through obstacles. The maximum usage time is one minute; if the quirk is exceeded, it automatically stops working.
Her personality is very similar to her mother's; she loves stories about when her mother was still studying at the same academy with the others. She loves the story of how Midoriya saved the world by sacrificing his Quirk.

Name: Kurosu Sugyou
Also a student of class 1-A.
A teleportation quirk. Sugyo can teleport to any point within a 10-meter radius. The ability has a 30-second cooldown. He doesn't need to be able to see the point he wants to teleport to.
He has a cheeky personality and loves to break rules, especially disrupting classes. He enjoys using his Quirk whenever it suits him. He considers himself the world's greatest hero, thinking everyone owes him something.

Name: Tetetoi Roki
Another student from class 1-A.
The Quirk alters his body, granting him four additional arms, and allows him to lengthen his arms and enlarge his palms.
He has a friendly personality, loves socializing, nature, and, most of all, loves hugs. He often invades personal space, but does so for the good, meaning no harm.

Name: Todoroki Ondo
A student in Class 1-A. Nephew of Todoroki Shoto, son of Todoroki Fuyumi.
This quirk allows one to change the temperature of an object by touching it. There are two black, circular stripes on each palm. By touching the plate to any solid (and later not only solid) object, one can change the temperature to any desired level.
His personality can be summed up as either "cold" or "lonely." He's precise, quiet, punctual, strong, and smart. In short, he strives to be the best, and he even succeeds. He tries to emulate his uncle, Todoroki Shoto.

Name: Kotetsu Neji
A student of class 1-A.
Steel Threads Quirk. He can release steel threads from his body through holes in his fingertips. The threads are thin, but still noticeable, not sharp, and quite strong. Releasing them is slightly painful, the threads are not infinite, and if a thread is lost, it takes about three days for it to fully regenerate.
The character is just like Katsuki Bakugo, and Neji's idol is also Bakugo.

Name: Sain Kopiar
Brother Sain. Also a student in Class 1-A, Jikan's brother, he's only a few seconds younger than him, but Jikan still mentions that he's older than Copyar whenever the opportunity arises.
His Quirk allows him to create an unlimited number of phantom copies of himself, but he controls each one himself, so the more there are, the more difficult it becomes for his brain. The phantoms, like Jikan's, are also intangible, but can become so for a short time at Copyar's will.
Copyar is mostly silent and polite with everyone, but occasionally he's very talkative and sultry, and he loves to discuss science and quirks, and even anime. When we're alone, we often talk to ourselves.

Name: Sain Jikan
Brother Pig, Copyar's brother, is a student in Class 1-A. He possesses a very powerful Quirk: he can create up to four phantoms that will either repeat his actions with a delay, or perform his actions in advance. These phantoms are either past phantoms or future phantoms, his choice. The phantoms are intangible; Jikan can teleport by swapping with the phantoms, repeating the same action or skipping an action by moving to the location of the phantom that performed the required action.
Jikan is usually very cheerful with his friends and the life of the party, very loud, and hates boredom. With strangers, he acts arrogantly, even toward those who are clearly stronger. In private, he is emotionless and very insecure, but he never reveals this side of himself to anyone.

Name: Izuku Midoriya
The teacher of Class 1-A. This is the grown-up Izuku Midoriya. After the events of the anime (which was even shown in the anime), he became a teacher at UA Academy.
