Crayon Shin-chan Planetarium-ban: Hoshizora to Gakkou no Nana Fushigi da zo!

Shinnosuke and his friends turn their eyes to the night sky, but a visit connected to their school soon becomes entangled with the legendary Seven Mysteries whispered about its halls. What should be a fun look at the stars grows stranger as familiar school spaces take on an eerie life after dark.
