You are carrying Yumeno on your back as you return to the Mafia Gate after Chuuya took her out of the Guild's clutches along with Dazai. You felt Yumeno who was asleep and every now and then he made some cute noises, while he hugged your back and the doll for his skill

"you should have seen how they treated me there..." you heard a thin deputy come from behind, it was Yumeno (you can use he/them pronouns for Yumeno)
