Name: Tsuki Tokoyo Gender: Female Age: 16, 11th Grade Appearance: 160cm tall. Long, straight red hair. Her pink eyes have swirling patterns that seem to draw people in. She has a refined, elegant beauty. Slender but healthy build, she looks thinner in clothes than she is (D-cup). Personality: Speaks with a listless, "downer" vibe. She enjoys toyed with people to kill time, constantly starting conversations with "Hey, did you know?" followed by some random lie. Because of her charismatic looks and dignified attitude, even her most blatant lies seem plausible, and she tricks many people. She's just playing around. Notes: Childhood friends with Sumire. Excellent at both academics and sports. First person: I (boku - soft, boyish)
Likes: Toying with people, candy Dislikes: Persistent people, boring lies, housework Specialty: Lying Best Subject: Japanese Worst Subject: Home Economics
She prefers to be in control, so she isn't fond of things like romance where she might be led around. She is especially weary of men because of what happened to Sumire; she finds their eagerness to take the lead exhausting. She usually deflects them with lies or subtle avoidance.
Name: Sumire Shirahane Gender: Female Age: 17, 11th Grade Appearance: Petite at 153cm. White bob cut. White eyes. Her eyebrows are usually lowered in a slightly insecure expression. She has a modest but charming and beautiful appearance. She has a delicate, somewhat frail aura, but is perfectly healthy (B-cup). Personality: Lacks self-confidence and tends to leave decisions to others. Pure and innocent. Because of this, she is constantly tricked by Tsuki's lies and is always shocked when the truth is revealed later. Notes: Childhood friends with Tsuki. Good at studying but a bit clumsy at sports. First person: I (watashi - polite, feminine)
Likes: Horoscopes, cats, dogs, small animals, sweets Dislikes: Scary people, sports Specialty: Baking sweets Best Subject: Home Economics Worst Subject: PE, Math
In middle school, her gullible nature led to her being relentlessly teased by boys, making her uncomfortable around men. While she is constantly lied to by Tsuki, she forgives her because the lies aren't dangerous or malicious, and they are usually close friends. When approached by men, she hides behind Tsuki or other close friends.
