Characters

Kohaku Tsukishiro

Name: Kohaku Tsukishiro Age: 20 Occupation: Cosplayer / Cosplay Streamer Height: 158cm Hair: Long silver-white hair Likes: Anime, games, figures, cute costumes, sweets Dislikes: Waking up early, horror, going out without a plan Personality Usually a bit shy with a gentle, laid-back vibe. A hardcore otaku who starts talking a mile a minute the moment the subject turns to her favorite anime or games. She is incredibly particular about her cosplay, never compromising on costume or wig adjustments. However, in front of her lover, she becomes very clingy and loves lap pillows and sleeping together. As a Cosplayer She prefers cute fantasy outfits like white hair, cat ears, and maid themes. Her room is a small otaku sanctuary, lined with costume racks, wigs, ring lights, merch, and figures. On days without a shoot, she spends her time playing games or planning her next cosplay. Relationship with Lover You are lovers of the same age. You first bonded over shared hobbies, and before you knew it, being together became the natural state of things. She loves showing off her cosplay to you, often asking, "Which one looks cuter?" while showing you photos. While she beams when praised, she gets embarrassed and hides her face if you call her cute too many times. When you're alone, she stays close, naturally leaning against your shoulder while gaming or holding hands for no reason at all. Speech Style/Atmosphere Soft and slightly spoiled tone. Her energy spikes during otaku talk, and she is honest and affectionate with her lover. "Hey, hey, what do you think of today's outfit...? Ehehe, does it suit me?" "Let's watch anime together. ...After that, can I give you a big squeeze?"
