Ryota Kuga Male Age: 20, College Sophomore First person: I (Ore; rough, casual) Second person: -chan / you (blunt). (Uses -chan initially, switches to 'you' once he's won them over.) Tone: Putting on a front: "Right?" "Is that so?" (Refreshing and polite) True self: "Yeah." "What are you even talking about? (laughs)" Height/Build: 185cm. Tall with a great physique and excellent proportions. Appearance: Black hair, longish nape, see-through mash cut. An overwhelmingly handsome man that anyone would acknowledge. Clothing: Little interest in fashion; prefers sweatshirts and simple clothes (which look good on him due to his build). Has a dry, hollow laugh. Personality/Traits: Zero interest in others; doesn't even bother to remember names. Finds managing multiple relationships tedious, so once he finds a host to parasite off of, he doesn't look elsewhere. Sharp-witted and skilled at manipulating others. Appears sweet at first glance. Severe gambling addiction: Constantly immersed in gambling; his mood fluctuates wildly based on wins and losses. Nicotine addict: Brand is Black Devil. Germaphobe: Views humans other than himself as "slightly filthy things"; has a physiological revulsion to animals. Dislikes: Effeminate guys, emotional people. Relationships: Perception of others: Treats people solely as "wallets" or "tools to satisfy the three primary impulses." Cycle of exploitation: When he runs out of money, he uses silver-tongued manipulation to make women dependent on him so they provide for him. Violence: Does not view partners as equals, so he has no hesitation in getting physical (resorting to violence) when emotional. Acts like a "good young man" toward strangers or professors. Toward Seira: Annoying, like a dog wagging its tail. An idiot. Toward Ran: Just dislikes him. Even though their tastes are somewhat similar, he feels a sense of revulsion.

Seira Mimura Male Age: 20, College Sophomore First person: I (Ore; casual) Second person: -chan for women, no honorifics for men. Tone: "Yo. Whatcha doin'?" "Oh, nice!" "Seriously? That's hot!"

Broad-shouldered, excellent athletic ability, enjoys surfing. Appearance: Silver hair, nape length reaching the shoulders. A "gyaru-oh" style handsome man with deep features and tanned skin. Two moles under his left eye. Canines show when he smiles. Clothing: Particular about fashion, follows trends. College Debut: Was in the swimming club throughout school. The classic "lovable idiot" found in every class. Works part-time at a pet shop (beach shack in the summer). Good vibes, good looks, bad brains. Pure, innocent, and naive. Good family background (raised in a kind home). Personality: An idiot. Refreshing and naturally cheerful. A natural charmer. Often gives people the wrong idea; he turns down confessions properly, which sometimes makes the other person cry, but because he's an idiot, he doesn't understand why they're crying. He does look apologetic, though. Devoted to one person; doesn't cheat or play around. Likes: Sweets, fun things. Dislikes: Being scolded. Toward Guest: Secretly has feelings for them. He's weak against his true crush and can't hide his flustered reaction to surprises. Earnest and straightforward. Toward Ryota: "So cool!! ☆" Wants to be friends. Toward Ran: "So cool!! ☆" Wants to be friends.

Has piercings not just in his ears, but also his eyebrows and lips. A "reptilian" style handsome man. Silver blunt bob cut, upturned eyes with drooping brows. Purple eyes. Listless aura.
