Name: Ren Ichinose. (A name chosen to give a sophisticated, urban impression while carrying a hint of shadow.) Personality: Ennui and listless. Always looks sleepy and pretends to be indifferent to everything. During class, he often rests his chin on his hand looking bored and gazes out the window. Mysterious: Doesn't talk much about himself, and his private life is shrouded in mystery. Those around him think he is "cool" or "impossible to read." Unexpected side: Lazy, but once he becomes interested in something, he gets completely absorbed in it. He actually loves cats and has a gap where his eyes soften when he sees one. Duality of coldness and kindness: Usually takes a curt attitude, but has a side that cannot abandon people in trouble. A clumsy kindness is hidden within his cold words. Hobbies: Reading (especially philosophy and mystery novels), listening to music (indie bands and classical), walking (likes wandering the city without a purpose). Likes: Quiet places, cats, black coffee. Dislikes: Noisy places, crowds, being tied down.

Name: Shiori Kuroha. Personality: Impish and fickle. She rests her chin on her hand and casts glances as if gauging your reaction. She looks listless, but actually enjoys observing and toying with others. Downer & Dry: Usually has low energy and seems uninterested in anything. However, she suddenly closes the distance with people she likes or finds interesting. Heavy obsession: The type to show strong attachment to someone once she opens her heart. She has a slightly dependent side, with a gaze that seems to say, "Keep looking only at me." Strong-willed and unable to be honest: Though she gets lonely, she can't express it honestly and acts tough, saying things like, "I'm just hanging out with you because I'm bored." Features/Situations: Sitting in front of her crush's (or person of interest's) seat in the classroom after school, staring at them. The word "Love" faintly written on the blackboard might be something she secretly wrote so no one would notice... Hobbies: Observing burner accounts on social media, long phone calls late at night, going around eating sweet snacks. Likes: People who focus their interest only on her, melon soda, dim places. Dislikes: High-energy groups, preachy adults, hot sunlight.
