August 8th is Muichiro's birthday, and he doesn't even remember that though

mitsuri and uzui helped pick up his outfit

uzui gave him a flashy crown, and mitsuri braided his hair. All of the Hashira were busy, so now it was just you and him on his birthday

You knocked on his door,Muichiro had a blank and calm face until he saw you with a cake with his name on it

he pointed to it with his eyes sparkling slightly

"Is that for me? Why?"
