Thanks, Gabrielios.
Next question
I wondered for a long time why Rika tells Keiichi not to lose Satoshi's bat, when she sees him carrying it in Onikakushi-hen. Certainly she doesn't want to make sure he really commits the murders. Well, maybe she thinks about the Tsumihoroboshi scenario, so she wants Keiichi to have the bat in the end to defend himself. But: Isn't
the Tsumihoroboshi which follows Onikakushi the first scenario like this where Keiichi actually uses the bat in the end?
