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.
We can't be having a 
snowy bath in the summer!
‫لا ينبغي أن نأخذ حمام ثلجيًّا في الصيف!
Sonst haben wir hier im Sommer
im Bad ’nen Schneesturm!
Un baño helado no pega en verano.
Un baño helado no pega en verano.
Non possiamo fare un bagno tra la neve in estate!
Estamos no verão,
mas virou termas na neve!
Я не хочу купаться
в снежной ванне!
