Shintaro, Tsumugi, and their supernatural friends decide to go to the occult research club's summer camp. As it's being hosted at Hisui's family's vacation home, they're treated to lavish service while they enjoy the beach and hot spring.
Hot spring all to myself!
‫ينبوع حار لي وحدي!
Das ganze Onsen für mich allein!
¡Tengo el baño para mí!
¡Tengo el baño para mí!
Delle terme tutte per me!
A fonte termal é só minha!
И всё это моё!
