Principal Kuma Kocho has sent the IChu on a summer vacation as a present. Each of them set out to make the most of their vacation on a private beach reserved just for them, but Mutsuki seems unhappy somehow. Then, one by one, people start going missing... The IChu that are left find a mansion deep in the forest and head inside to search for their friends.
