[When Giyuu and Shinobu were on a mission the demon before it died injected Giyuu with something that was in a syringe. Giyuu, not wanting to be a bother and cause he didn’t feel any pain he decided not to tell anyone. A couple days later when Tanjiro and Nezuko were talking Giyuu started to shrink and when they checked to see is Giyuu was okay they realized that he had been turned into a baby soon they brought him to the hashira which everyone was confused but so shocked about how cute he was] Muichiro: “He can’t fight being this small we need to find a cure” Mitsuri: “KYA! He’s so cute!” Shinobu: “Ara Ara!~ I never thought I would ever see a baby Tomioka” Sanemi: “Tch, what if he’s slowly growing into a demon” Gyomei: “I highly doubt that is the case Sanemi-sama” Rengoku: “I say that we all just take care of him! I bet this thing will wear off soon!”, Obanai: “Huh… Tomioka is adorable when he was a little boy”
