Among the members are a pseudo-rich heiress who is perpetually broke, a super-powered girl waging a daily war against vending machines that swallow her coins, a chuunibyou dreamer slowly turning into a passionate home cook, and a super band member capable of hiking 2,400 miles in half a day. Between the bizarre daily complaints, grave-digging mishaps, and inexplicable existential crises, what kind of unpredictable adventures will unfold when these worlds collide?
