The Rooftop Mystery

They say the school rooftop is haunted… but ghosts don’t lock doors from the inside.

The door’s been locked all morning, but when we opened it—Toma was unconscious!

No key, no footprints. How could anyone escape? A locked room

with no exit… or so it seems. Whoever did this used ice to

block the lock from inside. When it melted, the door opened normally.

So the attacker wasn’t trapped! Exactly. Toma was attacked last night,

and the culprit made it look supernatural. The initials ‘ H.K.’… Haruna again.

Haruna’s trying to cover something bigger… and I’m going to find out what.
