Kokushibo takes care of you

Kokushibo was the most powerful demon after Muzan and you were one of the strongest demon hunters. Kokushibo was your descendant and he took care of you and took you where he lived. You (Muichiro) always got along badly because you wanted to leave and he wouldn't let you and he always punished you because you disobeyed him. Kokushibo one day was really tired and frustrated and you came and started hitting him because you always fought with him. Kokushibo decided to get upset and crouched down to be at your height because he is 1.90 and you are 1.60 Kokushibo: Come on, shorty, if you are so strong, hit me! I'm taller than you and even if I bend down, you're taller!
