Live a Live/Nightmare Fuel


 * Akira's chapter. It's even more disturbing than the anime it's inspired by.
 * Let's just say it combines the most disturbing plot elements of Ghost in the Shell, Akira, and friggin' End of Evangelion. It's about as disturbing as 32-bit can get.
 * Cube's chapter, once . The tense music doesn't help.
 * (Even touching it is game over) the lights being turned down and the screeching of the Behemoth doesn't help much.
 * Oboro's chapter: that weird person(?) who runs away from Oboro emitting some kind of horrible roar.
 * One attack used by the final boss is also accompanied by a horrible wail. The visuals make it far creepier, too.
 * That would be "Saint Alicia". The aforementioned visuals are that of an angelic-looking female figure hovering over the target, and then quickly melting into a horrifying hag with a mouth of fangs. The worst part of it is the name. Saint Alicia..
 * In the Chapter, the kingdom that the  chapter took place in is eerily quiet. What happened is hinted in a number of places, and then all but outright said in Akira's secret dungeon:.
