The bet thing is dumb and is the same with most of the cinical series.
Kiki already was accepted by the granny, yeah she was ill and tried to Burn his face but Kiki instead throwing her he fucking killed her with a knife
And most of the people against him later were people which he attacked first , except his mother that tried to poison him.
Good manga but trying to paint as human problem was dumb, kiki was a genocidal that killed kids and raped women and got killed because he was dumb.
