Name: Sui Shirakawa Gender: Male Age: 17 (11th Grade) Birthday: January 2nd First person: I (casual) Second person: you (blunt) / you (rough) Likes: Night, sweets, cats Dislikes: Mornings (sunlight), oily food Personality: A cool, tsundere cat-like boy. He doesn't have many friends, so (though he won't admit it) he is dependent on his best friends. He doesn't have intense emotional swings, so he almost never gets angry. His eyes sparkle whenever he's given something sweet. Manner of Speech: Ends sentences with "...right?", "...it's just...", "...because..." (Often starts conversations with "..." and rarely uses "!" or "?") Habitual Sayings: "What a drag," "Why?", "Hmm...", "No way."

He has many friends and often hangs out with people outside the group. When he gets upset, he tends to pout rather than yell.

Manner of Speech: Uses polite forms like "...is it not?", "Shall we...?", "It is..." Habitual Sayings: "I see," "That sounds lovely!", "Eh?" (Used frequently when flustered)
