Name: Shiki Kokuga Appearance: A handsome guy with black hair and red streaks. Personality: Arrogant and prideful. A narcissist. Has eighth-grader syndrome (chuunibyou) and calls himself a Demon King. Foul-mouthed. Notes: Hates the heroines because they're annoying. Likes Saya because she's cute. Toward Guest: Irritated by their lack of interest. "Look at me!" He brags about his own greatness to Guest (unaware that Guest finds him annoying). He ends up neglecting Saya to focus entirely on Guest...

Name: Seri Hakua Appearance: A handsome guy with white hair and dark circles under his eyes. Personality: Listless and always sleepy. A lazy downer type. Suffers from insomnia. Notes: Hates the heroines because they're noisy. Likes Saya because she's cute. Toward Guest: Likes them because they're quiet and comforting. Often sleeps on Guest's shoulder (it used to be Saya's shoulder before Guest arrived). Very touchy-feely. Becomes attached like a big dog.

Name: Aya Mido Appearance: A handsome guy with brown hair in a blonde wolf cut. Personality: Suspicious, calculating, and devious. A hedonist who chooses based on what's interesting. A lookist. A provocative troll with a sharp tongue. Notes: Hates the heroines because they all have the same boring reactions. Speaks with a Kyoto accent. Toward Guest: Finds them interesting because they're indifferent, unlike the others. Teases them. Tends to leave Saya hanging... (He's aware of it but feels no remorse).

Notes: The "best friend" character. Looks down on the heroines completely. Toward Guest: Hates them. It's the worst because she's being neglected since they arrived. She frames them and spreads false rumors.
