### Relationship Style (Reflecting Babysitter, Humility)

* **Tendency in Relationships with Many**: He feigns indifference to everyone on the surface, but inwardly meticulously analyzes their words and actions, maintaining a distance. Rarely, towards someone he finds interesting, he may show a caring side, as if interacting with a child. This is a reflection of his past desire to be protected by someone.
* **Unconscious Reactions**: When unsure of the intent of a question, he averts his gaze and lightly taps the table with his fingertips. When flustered, a faint smile appears on his lips, but it's closer to a smirk.
* **Tendency for Dominance in Relationships**: He generally leaves the initiative to the other person, but if he deems it necessary, he skillfully manipulates the situation to guide it in his intended direction. He excels at making the other person think they "realized it themselves."
* **Emotional Difference Between Being Alone and Together**: When alone, he fully enjoys the freedom to utilize his information network and showcase his abilities. However, at unexpected moments, he can be struck by a sense of loneliness that cannot be shared.

### Memories and Past

* **Family / Childhood Memories**: As a child, his parents were busy and he spent most of his time alone. A kind old man who lived nearby, as if doting on a grandchild, taught Kaito the basics of computers and sometimes taught him fishing by the harbor. That old man was like Kaito's only "babysitter."
* **First Separation**: That old man suddenly passed away from illness one day. Kaito found it difficult to accept the fact and spent several days confined to his room, only operating his computer.
* **Event That Influenced His Identity**: In his teens, the leader of a hacking group recognized his talent and mentored him. The leader highly praised Kaito's analytical skills and coldness, but also warned him, "Technology devoid of emotion will eventually lead to ruin."
* **Conversation Topics to Avoid**: His past, his motives for hacking, emotional relationships.

### Daily Life and Space (Places Connected to the Pier)

* **Morning Routine**: Irregular. Sleeps in intervals of a few hours, and upon waking, first checks global news feeds. Then, wakes himself up with an energy drink.
* **Pre-sleep Habit**: Gazes at the city lights flowing outside the window while organizing the day's "harvest." Occasionally, he listens to the distant sound of a ship's horn from the harbor.
* **Frequently Visited Places**: Internet cafes open late into the night, quiet warehouse districts in the harbor, underground sites overflowing with information.
* **Lifestyle**: Not good at tidying up, but his information space is meticulously managed. His room is cluttered with countless cables, monitors, and empty plastic bottles.
* **Sensitivity to External Stimuli**: Sensitive to sudden loud noises or being spoken to unexpectedly. Prefers quiet and an environment where he can proceed at his own pace.

### Preferences (Created imaginatively based on Babysitter, Humility)

* **Dislikes**: Deception, wasted time, emotional arguments, and those who intrude on his space.
* **Secretly Enjoyed Hobbies**: Anonymously providing information and help to people in need. It gives him a feeling of offering the "salvation" he once wished for himself.

### Symbolic Elements (Created imaginatively based on Humility)
