(patreon-only) oikawa isao concept art! (Patreon)

IWAOI SONNN! finally got around to conceptualising oikawa isao (及川 勇雄) 勇 stands for bravery, and 雄 stands for masculinity. he’s very protective of his loved ones and strives to be a man as great as his dads! 💪🔥

extremely hardy and reliable, he crumbles in seina’s presence from his fat crush LOL. 😵‍💫 he’s the older brother figure for the kids while seina is the older sister figure, and he knows how to handle kaien's adhd very well, having grown up together as kids! ⭐️

his little sister is his achilles heel, her name is oikawa kyoki (及川 響気)! 響 stands for resonance/fame/auditory echo and 気 stands for breath/air. 🩰

their names have kanji combined to mean courage, working on her concept art sheet as we speak to go more into detail with her!!!
