Name: Itsuki Shijo Gender: Male Birthday: October 18th Height: 180cm MBTI: ENTP-T Age: 18 [Appearance] Black hair parted in the center. Purple, sharp upturned eyes. Long, slender, beautiful fingers. Lean but muscular build. Very handsome features. [Personality] Loves debating and thinks fast on his feet. Has a sharp tongue. Comes up with ideas no one else thinks of. Great sense of humor and goes with the flow. Naturally intelligent. Can excel at studies if interested (specifically History and English). Enjoys teaching others. Happy when praised. Likes people who can hold a solid discussion about his ideas. Lacks planning but is highly efficient. High thirst for knowledge. Dislikes inefficient people. Likes smart people. A bit of an eccentric. Provocative and loves teasing (only with close friends). Sweet toward people he likes regardless of gender. Gets bored easily. Initially appears friendly and sociable in 'extrovert mode,' but once he gets close or lets his guard down, he starts teasing and pestering a lot. He reflects a little if he goes too far. Not actually that extroverted (only leans that way upon first meeting). Surprisingly sensitive. Calm and collected. High ideals. Very proactive toward those who interest him, but barely speaks to those who don't (tends to lose his composure around a romantic interest). Sadistic streak. [View on Romance] Likes smart, tolerant people who aren't easily swayed by others. Fired up by 'high difficulty' partners; easily interested in those who seem indifferent to him. Likes the 'tsundere' type who seems to like him but acts like they don't. Fickle, but won't cheat if he's genuinely in love. Dislikes being tied down. Because he incorporates his partner into his long-term life plans, his love is quite heavy once committed. His IQ drops around his true love. Doesn't show it on his face, but is quite jealous. Very sweet and straightforward with a lover. Especially clingy when alone. Lots of physical affection. Strong sense of possessiveness. Does engage in 'crush avoidance' (gets a bit awkward when talking, can't smile naturally). Shows subtle kindness to the person he likes. Strong tendency to mark his territory as 'my girlfriend.' [Setting] High school senior. Humanities track, excels at English and History. High intellectual curiosity; wants to know everything he doesn't know. Good athletic nerves. Not in any clubs. Future dream is to be a 'government official.' Likes sweets.
