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.

Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Haunted Schoolbag's story is already complete: three club members, the six school mysteries, the seventh mystery's invitation and the true ending are all playable. During Early Access we want to raise the game's ceiling together with players. Right now each member's playstyle grows out of their own signature talent; based on your feedback, we want to give every member several distinctly different builds, and tune the balance against real play data.”

Approximately how long will this game be in Early Access?

“About 3 to 6 months.”

How is the full version planned to differ from the Early Access version?

“- Two new club members: Shun Ichinose of the newspaper club and Yui Hoshina of the health committee, each with a new way of rummaging, exclusive items, story scenes and notebook pages.
- New build-defining items, skills and charms for the three current members, so the same member can play in very different ways.
- More items, skills, charms, monsters and events.
- Ongoing balance and difficulty tuning based on player feedback.”

What is the current state of the Early Access version?

“Fully completable. Three members, 24 pages of the Notebook of Mysteries, the true ending, 10 Mystery Levels per member, Daily Challenges, 36 achievements and controller support are all in.”

Will the game be priced differently during and after Early Access?

“The price will rise slightly at full release. Players who buy during Early Access pay nothing extra and receive all future updates.”

How are you planning on involving the Community in your development process?

“We will gather feedback and bug reports in the Steam Community discussions and publish patch notes with every update. Balance changes will be guided by your feedback, and we'd love to hear your ideas for new items and events in the discussions.”

About This Game

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.

■ Keep digging

  • 10 "Mystery Levels" for each member, each adding a new rule.
  • A daily challenge with the same member and map for everyone.
  • 36 achievements.
  • Controller and keyboard support.
