You've just been sent into a school building as part of some sort of punishment. The conditions are simple: Explore the building for a bit. Should seem simple enough, right?
However, someone's in the building with you. And it seems they have homicidal intent planned.
Aka Manto contains examples of:
- Action Survivor: The good ending invokes picking up the Kusanagi-no-Tsurugi deep within the school grounds after making the proper offerings to its shrine, and running Aka Manto through with it.
- Air-Vent Passageway: You can move about in the air ducts around the school. Just watch out for the centipede.
- Animesque: The two fellow female students that force you into exploring the abandoned school look like this, which contrasts with the entire rest of the game having more of a realistic style, at least within its Retraux graphics.
- Antagonist Title: The game is named after the enemy.
- Apocalyptic Log: Tape recorders can be found throughout the school that play tapes when interacted with.
- Big Creepy-Crawlies: The centipede in the vents is HUGE.
- Cobwebs of Disuse: The inside of the school has quite a few cobwebs in it.
- Creepy Centipedes: A pretty big centipede is crawling around in the school's air vents.
- Disproportionate Retribution: Why are you being "punished" by fellow classmates into exploring a place associated with mysterious deaths and missing girls all over? A single throwaway line implies you got too close to one's boyfriend for her comfort.
- Hell Is That Noise: Being spotted by the Aka Manto results in it screaming as it chases after you, while a cacophony of a rushing heartbeat and instruments play to emphasize running like hell or being stabbed to death.
- In the Hood: The Aka Manto wears a big red hooded cloak that covers its body.
- Multiple Endings: The game has a good and bad ending.
- Notice This: Items that you can pick up have a red aura.
- Retraux: The game uses 3D graphics, but has very low-resolution textures, presumably in order to emulate classic horror games from the original Playstation. However, while other Retraux horrors going for the same aesthetic have also emulated the third-person perspective with fixed camera angles (i.e. Back in 1995), this game is still played in first person, like the much more modern Amnesia: The Dark Descent-style horror games.
- Screw This, I'm Outta Here: The bad ending is managing to get the right conditions together to escape the school from the rooftop, but ultimately this means there's no resolution to Aka Manto and more people will inevitably die if they go near its haunting grounds.
- Through the Eyes of Madness: When Aka Manto spots you, the screen fills up with Japanese text telling you to flee, and in both endings, with no proof of the Aka Manto remaining whether it lives or dies, it's questionable if the protagonist even actually met the entity or the whole haunting was something more psychological.
- Was Once a Man: The implications of the Apocalyptic Log throughout the game is that a new student of the school that was bullied, Atsushi, ended up dead under mysterious circumstances matching Aka Manto murders, and then transformed into an Aka Manto and racked up a high enough body count to force the place to close down, leaving him haunting it.
