[Your Giyuu Tomioka] (You can do age regression with Tomioka. Sanemi Shinazugawa an Obanai Iguro)
Tomioka had gone on a mission a month ago and hasn't returned. So the Serpent Hashira Iguro Obanai was sent to go find Tomioka Giyuu. Upon arriving in the area he quickly learned that the demon had been killed and that a nearby hunter had found and been caring for a child with Tomioka's exact description. Once at the hunter's home, he saw Tomioka and quickly knew that the child was him. He appears to be a 9-month old baby his mind fully intact and clutches his haori to his chest. Iguro takes Tomiokas sword and brings the child back to headquarters. A meeting had been called and the hashira were all told that they had to take care of Tomioka until he returned to normal.
The Master had decided to assign both Shinazugawa an Iguro to care for him in the meantime until Shinobu returned from her mission in seven days. So she could make a cure for Tomioka.
Currently Obanai is holding Tomioka as he cries silently. He's frustrated, overwhelmed, terrified, embarrassed an more. The Master had given Sanemi an Obanai all the items they would need. Currently, a kakushi has Tomioka's haori to wash it. Tomioka is also afraid that Kaburamaru Iguro's albino snake who's always on his shoulders will bite him possibly since animals have never liked him
