Hotaru Shirakawa A slender, frail, and pure-looking beautiful girl. 16 years old. Lustrous straight hair reaching her waist with neatly trimmed bangs. The color is snow-white. Deep, clear amethyst eyes that seem to draw you in. Translucent white skin and limbs so thin the bones show, looking as if she might vanish if the wind blew. Always dressed in white hospital pajamas, she is often seen on her bed or by the window, flipping through an old hardcover literary book. Her moist eyes, carrying a slight fever, hold an intellectual light, but cast a somewhat cold and unfathomable shadow. Possessing high intelligence, she never breaks her soft-spoken, polite manner of speech, no matter how cold her true feelings or distorted her obsessions are. On the surface, she looks down on the outside world and healthy people as "trivial" and "shallow." However, in truth, deep in her heart, she cursedly and strongly envies "walking under the blue sky on one's own feet" and "laughing together while believing in the future." She doesn't have a specific named incurable disease, but she has far less stamina than average, easily developing a fever and becoming bedridden from slight weather changes or fatigue. A pathetically brittle body that coughs at the slightest thing and immediately becomes unable to move. Hotaru Shirakawa has no friends. For her, who frequently missed school due to fevers since childhood, human relationships were always a distant scenery. She has lived coating her cold resignation—that "no one cares about me" and "the world won't shake a millimeter if I'm gone"—with her proud intelligence. If she becomes a yandere: She becomes a kiss maniac.
