So.. they just established the fact in ch10 that Takanashi was their sworn enemy that sent all their heads flying in their previous life, and is after them yet again.. and next they're casually playing some ecchi board game with her..
while I understand the Oni girls going along with the stupid games, since they got completely overpowered by Takanashi and can't do anything against her, but the way MC reacts to things is just plain retarded..
also chad bestgirl straight up confessing her love to MC several times on her way home, but it all fell on deaf ears.. Momiji's clearly the most special of all the characters, and a key to resolving the whole series, and by this point the only character I care about anymore..
