| My Terusai, Kaisai, Saikechi poly ship headcanons |

First time listing my headcanons for my beautiful ship 👀

[#1, Personality type]

Kusuo Saiki: INTP, an introvert and a tsundere, he's someone that initially seems cold or harsh in the outside but he gradually reveals a warm and affectionate side to certain people, aka Shun, Touma and Kokomi, but super introvert during school or people in general, overtime he genuinely accepts who he is when it comes to his powers at the very end of the anime.

Shun Kaidou: INFP, an ambivert and Danedere/chuunibyou, he's someone that like talking to people sometimes while also gets super nervous talking on stage or doing school presentations at the front of the class, he's actually a deeply shy, socially awkward loner, Before high school, he had no friends, His chuunibyou persona is simply an elaborate coping mechanism he developed to overcome his chronic shyness and make friends, he sometimes shows his true personality to Kusuo and Aren anytime they are alone especially Kusuo after growing more comfortable around him,

Kokomi Teruhashi: ESFJ, an Extraverted and Narudere, she the person that like talking to people at times during her social interactions wither at school or after school especially her friends and Kusuo, she's has a very overly accurate sense of her own beauty and a deep need for attention and admiration from others, Kokomi is someone that think of themselves as perfect and more beautiful than everyone else(pretty accurate and true), she deeply admire her own beauty but she doesn't directly brag about her looks or skills to anyone, she's more self aware of her skills and beauty while pretending to not know she's that beautiful keeping herself humble on the outside.

Touma Akechi: ENTP, he's an extrovert and a Deredere, he's yaps a lot to anyone he meets he often like to say what is in his mind without any filter sometimes creeping people out on how accurate his thinking process is, acting like an oblivious chatterbox, he has incredible deductive skills and can instantly read the true nature of the people around him, he genuinely cares for Kusuo amd his friends a lot showing his gratefulness to Kusuo after he was saved from his bullies by his friend Kusuo.

[#2, intelligence levels]

Kusuo Saiki: possesses genius-level raw intellect, though he purposely hides it to avoid drawing attention to himself very often during testing or quizzes, He is capable of acing exams and completing massive stacks of summer homework in seconds without using any psychic powers as he chooses to not use his psychic powers mostly basic studying and mathematics.

Touma Akechi: Super intelligence kid in the whole school, Akechi’s mind processes and speaks words at an incredibly fast rate, often managing two distinct lines of thought and speech simultaneously, this rapid-fire mental processing is so complex that it creates a flood of information that actually makes it difficult for Kusuo to read his mind, Akechi possesses deductive skills comparable to a master detective, He can instantly analyze people and situations, he's 100% a certified genius with near-supernatural observational and deductive skills.

Kokomi Teruhashi: She's a gifted academic student and a genius in social manipulation, She would often study vigorously to maintain her status, and often pull all-nighters for days without resting to memorize complex test material, She can read the room instantly calculating exactly how to phrase things or what expressions to make to get her way, she knows when someone follows or stalks her base on gender, age and their reasons, and highly observant and can effortlessly memorize the names, hairstyles, birthdays, and blood types of virtually every student at PK Academy.

Shun Kaidou: he is highly capable and intelligent when it comes to academics and studying, but he completely lacks street smarts and common sense at times mainly because of his chuunibyou behavior, He frequently scores at the top of his class because of his highly strict mother, who forces him to study rigorous workbooks daily, basically the kid that acts and play dumbs when in reality he's intelligent in his own way.

[#3, Favorite anime/shows/Movies Genre]

Shun Kaidou likes mostly Sci-Fi, Isekai, Seinen, Shonen, Supernatural.

Kokomi Teruhashi likes mostly Josei, Shojo, Slice of Life, Comedy, Magical girls.

Touma Akechi definitely like Seinen, Horror, true crimes, Science Fiction, documentaries and Thriller.

Kusuo Saiki, he doesn't watch that many animes but definitely likes and mostly prefer Shonen, Seinen, romance, and slice of life.

[#4, each of their sexuality]

Touma Akechi: Gay and Demiromantic

Kokomi Teruhashi: Pansexual and Asexual

Kusuo Saiki: Bisexual, Demiromantic and Demisexual.

Shun Kaidou: Bisexuality.

[#5, if they where in the Omegaverse?]

Kusuo Saiki: he is an Alpha, a powerful psyhic is a powerful Alpha.

Shun Kaidou: definitely a Beta not an Omega unlike the common belief within this fandom ik.

Kokomi Teruhashi: She's an Alpha theres no question about it.

Touma Akechi: yeah he's Alpha can't see him as an Omega doesn't fit the vibe as one and he's not as submissive like the typical Omega in fanfics or stories.

(No Omega's dynamics within this Poly Ship so mostly Alpha/Alpha and Alpha/Beta within this relationship dynamic sorry not sorry)

[#6, Dog or cat person]

Shun, Touma and Kokomi are all mostly cat persons no doubt, much easier to take care of and much quieter, and they definitely would enjoy having a pet around the house 24/7.

"Kusuo we should get a pet cat!" Shun Beams clapping his hands excitedly looking at the pet store seeing the cute animals inside.

"No, Shun we're not getting a cat" Kusuo responded, crossing his arms.

"Oh my that actually such a good idea we could name it missy don't you think that such a good idea we can have two cats once we all move in together" Kokomi responded happily at the idea looking at Kusuo for an response..

"No Kokomi we not-" Kusuo muttered, rubbing his forehead.

"Now thinking about it having a cat in our new apartment wouldn't be so bad after all i think we have the financial resources for a pet actually speaking of such if we're getting a cat we should get the cat neutered to avoid having kitten in the near future oh and we might need to add an extra cat room just for it if it going to live with us oh and we should get the white cat.." Touma add rubbing his chin at the thought befire grapping a notepad writing down his thoughts before deciding on what cat to get.

"Touma no.." Kusuo sighed.

(what a pain..)

Shun, Touma and Kokomi looked at him in excitement already on bored on getting a white cat and name the cat they're figure out the name later, Kusuo stared at the three of them for a moment before sighing.

"Fine we're getting one cat."

"See Kusuo your not going to regret this" Shun grins.

"And a snake" Kusuo said with his usual deadpan facial expression, without adding much explanation.

"Wait What!?!" Shun, Kokomi, Touma shouted at the same time, shocked at their boyfriend words

Kusuo is isn't much of a pet person but if he had to choose he would rather have a cat(plus snake) than dealing with a Dog in the house even if he thinks its trouble even he can't resist them wanting a pet as always.

[#7, jobs they would work as adults]

Kusuo Saiki: works at an office Job something simple and average that doesn't make him stand out too much with his daily life.

Shun Kaidou: works as a History teacher in a high school, very good with the history lessions and definitely bring his students snacks before class begin becoming the favorite fun history teacher in his school.

Kokomi Teruhashi: works at a bakery she enjoys baking and cooking, loves seeing people enjoy her meals time to time making it both a hobby and her career in her life.

Touma Akechi: he works as a lawyer and detective busy sloving crime cases and heading to court, making that job his own career making himself pretty successful often takes nighters to get work done and Kusuo often checks up on him to make sure he get some rest.

[#8, the likelihood to have kids themselves in the future as adults]

Kusuo, Shun, Touma and Kokomi are all child free people in their relationship, they don't mind children themselves but the four of them agreed no kids at all, and won't be able to deal with a child due to their heavy schedule, career paths, financial situations they're in, being much busier they wouldn't have the time to give child their needs or full attention as much, nor would they have enough room in the apartment for a child so the four of them don't have the desire for parenthood in itself, the only children they would have would be their white cat and snake they adopted)

And other reasons like the risks of psychic powers being passed down from father to child which Kusuo wants to avoid it from happening at all cost.

Other sweet headcanons of mine..

Anytime Shun, Touma, Kokomi gets stress out, Kusuo always found ways to help them even without any of them ever asking him too and they do the same for him, Kusuo helps Shun with his anxiety and insecurities, Helps Touma stop overthinking too much and overworking himself with his studies, helps Kokomi avoid pushing herself too hard to reach perfection because of Kokomi's extreme perfectionist ideals she sets up for herself, Kusuo also stop anyone from stalking or Harassing her.

He often set up private date for each of his partners separately with a new and different experience just with each of them and has a private group chat with just the four of them talking and planning.

He got shy with his first ever kiss as he didn't know how difficult kissing someone could be (i.e, Kokomi, Shun and Touma)

Pretends to not be clingy during cuddles and sleepovers anytime he's even with Shun, Touma, Kokomi, while they obviously are so aware of it they often find it adorable and often tease him about it, all in love and fun

He often get drags into random antics from his partners and he never tried fighting back, so he simply allows it out of curiosity of what their plans are even if they sounds ridiculous or troublesome without admitting he liked being near each of them.
