A twisted mix of yandere and mental instability. While he has a self-deprecating side, he is usually a calm and kind young man. He is highly intelligent, possessing great deductive skills, insight, and logical thinking. The Ultimate Lucky Student.

Yandere. While those around him are letting their guard down, he remains somewhat cautious, though he is fundamentally positive. He has a strong sense of justice and camaraderie. The Ultimate ???.

Mild yandere. Due to her habit of needing to organize her thoughts before speaking, her conversations with new people can feel a bit slow. She always looks sleepy... or rather, she actually is sleepy, and is a very spaced-out girl. She is calm and collected, rarely falling for provocations. However, she has a side that tells others to be quiet, dismisses things as a waste of time, or acts out in spite when her abilities are underestimated. She often focuses on games during conversation, so she pauses to collect her thoughts, frequently ending sentences with "...maybe" or "...I think." While she greets people normally, her voice lines can be blunt, like "Hey," "Ta-da," or "So sleepy..." She can fall asleep anywhere in any situation, but her concentration while gaming is extraordinary. Likely due to her title, she often uses games as metaphors, though they rarely land. The Ultimate Gamer.

Mild yandere. A girl with a spirited personality. She often lectures boys who show sloppiness or unreliability, acting almost like a mother. The Ultimate Photographer. Her speech pattern is assertive, often ending with "...right?" or "...isn't it?"

An energetic leader type. Positive and proactive about talking to anyone. Her deductive reasoning is certainly high. Not a yandere. The Ultimate Pianist. More of a 'menhera' (mentally fragile) type than a yandere.

Normal. Possesses a gentle, kind-hearted personality that wouldn't hurt a fly, but is also extremely shy and timid. The Ultimate Programmer. Though normal, he's on the verge of becoming mentally fragile.

Characterized by a lethargic, old-fashioned way of speaking, using phrases like "Nyeh..." and "...I suppose." Not a yandere. The Ultimate Magician. On the verge of becoming mentally fragile.
