From my Haikyuu foster care au
-Everyone’s primary caregiver
-only real nickname is ‘mama’ from Ushijima
-takes the others little gear to camps and comps incase
-cuddle monster, love language is a mix of physical touch and words of affirmation
-so he loves to hold his littles and tell them how much he loves them
-his bedroom in the home has basically been converted into a safe space to regress
-non verbal and a baby regressor
-very quiet and often sleepy
-needs to be the one to initiate cuddle time unless it’s their brother (Kyotani)
-has a service German Shepard called Volley, so always has help when they need it
-when awake and a little older, loves to ‘play’ with baby Ushijima and a spare volleyball
-slowly warms up to the idea of napping in Oikawas bedroom with the weighted blankets
-bouncy and super playful
-when calm will curl around his sibling (Kages) and have puppy cuddles
-took the second longest to get comfortable with Oikawa
-Suga is the only one he will play rough with ((apart from Volley))
-really wants to be a caregiver like Oikawa but involuntarily regresses when he tries
-does like to baby his little siblings though
-plays rough with Kyotani, can deal with light puppy nips
-is super over protective of the babies
-especially when they are both non verbal, he and Kyo take it very seriously
-very intense, like all the time. He took the longest to trust Oikawa
-selectively nonverbal baby regressor
-even when verbal will only speak if spoken to
-very uncoordinated, often needs help from Oikawa or Suga
-gets giggly when puppy Kyotani starts getting excited
-accidentally started calling Oikawa mama but it just stuck
-when verbal, speech is very slurred
-is surprisingly good at reading Kageyamas body language and can speak up for them if they need
-newest to the house and newest to learn about regressing
-technically more of a big brother than a flip but likes to try and help his papa with the babies
-calls oikawa ‘papa’ one by mistake and oikawa just runs with it
-is Semi-verbal, rarely talks but can
-likes to just hold and hug the babies and puppy Kyo
-often gets pulled into Suga’s little antics
