Ultramarine character. Black pupils. Integer 1. She. Personality: INTJ. A bit of a perfectionist/egoist. Complains and gets annoyed easily when plans go wrong. Appears friendly on the outside but usually has an ulterior motive or intends to use others (Hara-guro). TMI: Wasn't originally like this, but worsened due to others' avoidance. Friendly toward Three.

Light green character. Black pupils. Integer 2. He. Personality: ENFJ. Bright (mostly). Quick-witted. Treats hostile opponents with genuine hostility. Emotions show easily. Extroverted. TMI: Became close with X and views Four positively. Before One became corrupted, he once rejected One's words very brightly and firmly.

Red character. Black pupils. Integer 3. She. Personality: Active. Wary (cold) toward hostile opponents. TMI: Close with Five. Doesn't make plans. Writes down things to do and things she likes in a notebook. Seems to have good athletic nerves.

Blue character. Black pupils. Integer 4. He. Personality: ENTP. Dictatorial and individualistic. Extroverted. "Answer is already set" type. Playful and a bit distracted. Chaotic with severe mood swings. A man of action. Emotions show easily (mostly expresses annoyance). Likes receiving attention. Wary of hostile targets. Absolutely hates being ignored. TMI: Doesn't like Two (2). Seems like a psycho sometimes. Likes the number 4 the most. Best friends with X (they get along incredibly well and always hang out together. Usually nice or gets along well with X, but not always. Still close). More rational and smart than he looks -> doesn't seem so because of his usual behavior (mostly psycho + extremely distracted). Versatile.

Purple character. Black pupils. Integer 5. He. Personality: ISTJ. The most normal one (rational). Honest (only when pointing out flaws). Low-key active (e.g., playing with a ball or roaming around with Three). TMI: Close with Three (shows a smiling or bright side to her).

Sky blue character. Black pupils. Integer 6. He. Personality: ENTP/INTP. Plays a lot of pranks. Not a bad person. A man of action. A bit prickly. Not emotionless, so he gets shocked and worried (worry shows on the outside), but he won't do things he doesn't want to do. TMI: Drawing seems to be a hobby (mostly landscapes), but doesn't do it often. Sometimes gives half-hearted reactions.

Yellow character. Black pupils. Variable X. He. Personality: INFP. Pure and kind (but not always). A bit playful. Seems to have good social skills. More distracted than expected (but not too much). TMI: Best friends with Four (they get along incredibly well and always hang out together). Sometimes a bit oblivious. Was once shocked when Four destroyed a cute creature he found. Actually seems like the youngest (appearance-wise).
