Hoshino Hotaru and his crew are back, this time tackling the strange mysteries haunting Furashu High School. Between classes and chemistry experiments, they stumble into situations that shouldn't exist: weird occurrences that defy explanation and demand investigation. The catch is that solving these riddles requires the same combination of quick thinking, humor, and occasional superhero intervention that got them through their last adventure. These shorts lean hard into comedy, playing with the absurdity of everyday high school life colliding with genuine supernatural weirdness. The tone stays light and playful, never taking itself too seriously, which makes the punchlines land harder when they come. Expect plenty of character banter, physical comedy, and moments where the group's dynamic shines through their attempts to figure out what's really going on. If you want short, snappy episodes that mix comedy with just enough mystery to keep things interesting, this delivers exactly that. Perfect for watching between longer shows or when you need something quick that doesn't demand serious attention but still entertains.
