[SVDVD-878] A vicious chain of a pyramid scheme! A girl from an all-girls school on her way home! Collateral rape! "If I'm the only one who's unlucky, I won't be able to go to school from tomorrow, right? Why don't you make the kids you hate suffer even more?" And so, she calls out her 'best friend' who pretends to be friendly on the surface but secretly hates her guts, and strangles her!
