- Breather Level: When playing as full-size Narue against Mouse World opponents, the battles are (obviously) the easiest in the game.
- Cry for the Devil: The video diaries are there to give the player a chance to see the Vice-Director's Start of Darkness, and thus humanize a character who generally acts like a murderous Jerkass.
- Demonic Spiders: Almost EVERY enemy (including actual spiders) in the game has an ability that will give them two physical attacks in one if they choose to use it, and some bosses will even be able to attack twice separately in the same turn. Even worse, in later sections of the game, certain enemies are able to launch off rather potent combos of status effects. Alone, and used once, the status effect is generally ignorable, but when two enemies somehow get two attacks per turn, and each enemy uses the incapacitating attack twice on different characters, they can rather effectively prevent your entire party from attacking. Most noticeable upon the eventual regrowth of your characters and all the girls are suddenly accompanied by genetically mutated lions.
- Jerkass Woobie: The C-Rank Member, after her Trauma Conga Line. Chijinda makes his opinion very clear: nobody deserves what happened to her.
- Nightmare Fuel: True to Kyon's statement, Erika's stomach does not disappoint. Beyond the concept, it's a nest of cells with faces, half-digested vaguely human-looking figures, half-eaten fish that are still swimming around, and gnarly looking experiments that were "disposed" of.
- That One Attack:
- A powerful Bonus Boss, Tatarigami, has an attack called "breath of the grave". It inflicts whoever it hits with just about every status effect in the game. Mind you, several of these completely immobilize the target, and the attack hits you entire party. Being entierly immobile as other status effects and Tatarigami's own powerful attack ware you down is NOT fun.
- Seemingly every enemy having Renzoku may qualify as this. It is an attack enemies can more or less use indefinitely that allows them to hit you twice, and the damage from this can add up very fast if you're fighting a group. One boss in particular will use a move to increase their attack power, then follow it up with this move, potentially KOing someone in one shot.
- Woolseyism: Much of the original Japanese script was simple and bare bones dialogue. Several lines were expanded or added in the English translation.
