Haunted Schoolbag

When the lights go out, the school's Seven Mysteries wake up. Reach into a pitch-black schoolbag: grab a hilt to pull out an item, touch a blade and get cut. Read the numbers, build your bag and survive the night with three club members. A minesweeper-like roguelite of Japanese school ghosts.

8:50 p.m., the back gate of Hoshimi Academy. Not a single light is on.

Once every ten years, a blackout wakes the school's Seven Mysteries. The Occult Research Club takes them on one night at a time — armed with nothing but a schoolbag full of stationery. The problem: you can't see inside it.

■ Blind-grab inside your schoolbag

Touch an item's hilt and you pull out the whole thing and use it at once, for free.
Miss, and the revealed cell tells you how many hilts (yellow) and blades (red) are around it.
Touch a blade and you get cut, losing courage and HP.
Your bag is reshuffled every turn, so every reach is part deduction, part gamble.

■ Three club members, three ways to grab

Minato (club president): a natural detective. Cells that must be hilts are marked for you.
Akane (the delinquent): "It's just a scratch." She yanks items out even by the blade, and grabs whole handfuls at once.
Suzu (the shrine maiden): the first item she draws each turn stays fixed in place, ready for her next turn.

■ Pack your bag

96 items: pencils, scissors, recorders, wooden swords, sacred arrows, and more. Each has its own shape and its own hilt and blade cells.
90 skills and charms that change the way you grab.
Organize a main pocket and a side pocket with limited space.

■ The Seven Mysteries

50 apparitions and 6 bosses, including Hanako of the third-floor restroom, the after-school broadcast, Kokkuri-san, and the third bed in the nurse's office.
They stuff your bag with fake hilts, cursed coins and pillows, lock your side pocket, or turn off the lights.
34 random events, a late-night school store, and the clubroom.
Seal all six, and the Seventh Mystery sends you an invitation.

■ The Notebook of Mysteries

After every run, new pages open based on what you achieved: 24 short scenes, each with its own illustration.
New club members, items and skills unlock along the way.
