The Secrets Of Giyuu Tomioka

AU(S)/Headcannons for my story (Most about Giyuu)

(AU= ~ and headcannons= -)

- Giyuu usually takes care of the Kamaboko squad ( including Aoi, Muichiro, Genya, and Senjuro and butterfly triplets)

- Giyuu sometimes helps Aoi at the butterfly mansion if Shinobou is on a mission or just busy in general

- Giyuu usually has to force Aoi (and sometimes the butterfly triplets) to take a break to eat or take care of herself

- Giyuu loves to read anything to anyone who'll listen ( most of it is pretty morbid though so no one really tries to listen)

- Giyuu is a amazing cook/baker and teaches Aoi sometimes

- Giyuu has a scar from final selection above/through his eye and wears makeup to cover it and was slightly blinded from the attack

⚠️Mentions of pedophilia⚠️
Suma and her wives(And ig husband) are newly weds(Mainly because I don't want Tengen to be a pedo by marrying Suma when she was eleven and when he was fifteen)

~ Trans (ftm) Giyuu (A.N-If I put headcannons underneath a AU it connects/results to the AU)

- When ever he get his period he is even more quiet but when he does talk he is super sassy/mean and gets a week off (Mainly because the master notices he lashes out a ton more and is concerned for everyone else's safety because of how aggressive Giyuu gets)

- He refuses to let Shinobu to do a physical check because he tries to hide that he is trans (The only adults that know are the master and Mitsuri and Suma but the Kamaboko squad also know) and doesn't even go to the butterfly mansion when he's hurt

- He wears the mask Urodaki made for him to hide his feminine features (Sometimes even at home alone because he forgets he even wears it)

- He doesn't speak unless he has too because of his feminine voice

-He didn't transition until the age of 16

~ GiyuuMitsuSuma cousins

- They usually has a sleepover atleast once a month

- Giyuu is usually invited to 'Girl's night' but Mitsuri and Suma made everyone call it 'Girl's and Giyuu night' (Because of above)

- Mitsuri and Suma are the only people(besides the Kamaboko squad) that are allowed to see his face and sometimes even helps him do his makeup (despite him wearing a mask)

- Giyuu helps Suma(And/or Mitsuri) do her hair and vice-versa

- Mitsuri can cook a bit and Suma can't cook to save her life so, Giyuu usually makes them food when they visit

~ Split Japan/ TPN x MHA x KNY

- So basically halfish(A.N- Not sure if that's a word but IDC lol) of Japan is split ever since demons had became a thing and people could go to the other half and there are quirks in the more advanced part of Japan. And there are demon farms in the other half made by cults like Obanai's family(A.N- I just wanted to add this since in a future story I will make Deku be Gilda in the past and I didn't want to make something on the spot when I do write this again) I also didn't want to research a ton on stuff back then and I wanted to add hoodies and other stuff like that

~Karl and Gary friendship (Some inspiration from @Caitpatmosh on tt for the kokugiyuu friendship)

- Giyuu trusts his number one secret with Kokushibo

- They can never get each other's names right/ don't want to[It had eventually become a inside joke between them(and the other uppermoons)]

- They met at a lake at night and they started to get along very well and started to plan meet ups after a few days of talking and eventually he(Karl) had became Giyuu's male best friend

- 'Karl' knows about 'Gary's #2 secret (being trans)

- Karl has a room in Giyuu's place and vice-versa

           SAD HCS STARTING NOW ⚠️Pedophilia, grooming, manipulation, r@pe/SA, child abuse,child experimentation, child neglect, starvation, etc/more stuff like this ⚠️

~ Didn't run away(BTW Giyuu was ten when his sis died)

- Giyuu had stayed with his 'uncle' for a year

- Giyuu's 'uncle' found out the Tomioka family has some kind of poison immunity in their blood

- The 'uncle' only fed Giyuu enough to keep him conscious which led to Giyuu being very fragile and weak

- The only reason Giyuu was able to escape was because his uncle had beat him so bad that he thought he was dead and dumped him in the snow and Giyuu decided to run for it and everything else happened like cannon

~Secret (bio) daughter (#1 secret basically)

(Context)- After Sabito's death, Giyuu(thirteen) went on a mission(after mourning for a few weeks) and had met Jigoku Kiyoshi(who was twenty seven)who had 'helped' him get over the death, by telling Giyuu that he would be a 'friend', a 'special friend', who would do what they wanted to Giyuu. He(Kiyoshi) had convinced Giyuu that he loves him and vice-versa(*cough* Stockholm syndrome *cough*) and had forced Giyuu into marriage with him saying it would 'benefit' their 'love'. Soon after it Kiyoshi had showed his true colors and had forced himself on to Giyuu multiple times resulting in their daughter, Petal. When she was two (Giyuu is fifteen now) a demon had attacked their home, Giyuu had slayed the demon but not before it attacked Jigoku and Petal. Jigoku was in a bad condition while Petal in bit better condition and Giyuu had taken them to a infirmary and Jigoku had been put into a coma while Petal was healed with only slight scarring. (Guess what I'm tired so-) But she got turned into a demon almost like Nezuko.

- Petal cares greatly for her family

- Petal doesn't even know that she's a demon because Giyuu tries to avoid the topic

- Petal loves her aunties(Mitsuri and Suma) and (unofficial)  siblings

- Petal is usually at the infinity castle for Thursday brunch and gets watched by Akaza or Kokushibo when Giyyu is busy with a mission or whatnot
