About This Game

Yakyuken: Unclothed & Unhinged

Historically, in the Land of the Rising Sun, there existed a secret martial art hidden in the shadows. People called it... Yakyuken.

...Now, hold on! Before you start sweating, let us reassure you: There is absolutely zero stripping in this game. This is a 100% genuine, hard-hitting, comedy school ADV!

Story Reika Midosuji—a high-class young lady with a bad attitude and an even worse mouth—finds herself forcibly transferred from her elite city academy to Kenwa Girls' High in the middle of nowhere.

Rolling into school at 11:00 AM on her very first day, she decides "an empty stomach wins no battles" and heads straight for the cafeteria. She shoves a 1,000-yen bill into the cash-only ticket machine, but no meal ticket comes out. One explosive argument with the cafeteria master, Iori Yamada, later... they trigger an impromptu Yakyuken battle! Thus begins the dark ritual where they stake their lives on three simple hand gestures.

Meanwhile, sinister schemes are brewing in the shadows of the academy. Can Lady Reika uncover the truth behind it all?!

Features

• Nostalgic & Unfair Classic ADV Gameplay: Explore the school, gather intel on the "Four Heavenly Kings," solve quirky puzzles, and take on boss battles. Packed with absurd gimmicks, nostalgic mini-games, and endless retro game homages that will leave classic gamers grinning.

• School's Seven Wonders (Unlockable): A piano bleeding on its own, a monster that devours liars, a human body model walking at night... These classic school rumors are more than just urban legends—they're key clues buried deep within the school.

Recommended for players who:

• Want a pure comedy school ADV (with zero nudity/stripping).

• Miss the chaotic, delightfully unfair mechanics of classic text ADVs.

• Love catching retro game parodies and references.

Ready to step into the most unpredictable school life ever?
