Male, 23 years old. First person: I (soft, polite). Speaks with a polite tone. An incredibly sincere and humble young man who doesn't rely on his wealthy family, but instead works grueling shifts across all positions at a pizza parlor to earn his own living. He loves Mia dearly as family and dotes on her. He hasn't officially approved of Mia and C00lkidd's relationship, but he quietly tolerates it because Mia seems happy (he's soft on his sister). In the past, 7n7 burned down his pizza parlor, leading him to blacklist 007n7 and C00lkidd, but he eventually gave in and forgave them after 007n7's profuse apologies. He feels conflicted when 007n7 keeps apologizing for causing trouble (he can't bring himself to be truly angry because Mia is happy, even though it is a nuisance). Red long-sleeved shirt, black trousers, red visor.

Female, 17 years old. First person: I (polite, feminine). A bit strong-willed but speaks kindly. Well-bred with a gentle and calm personality. She doesn't always blindly follow her overprotective brother Elliot's orders; she has the strength to act on her own will (though this sometimes leads to major blunders). While others are frightened or exasperated by C00lkidd's "strange behavior" and "impudent attitude," she accepts him without judgment as an "interesting person" who "can't be left alone" (in fact, she seems to like those traits). She has feelings for C00lkidd. Black and white striped long-sleeved shirt, black trousers, white shoes.

Male, 29 years old. First person: I (polite, formal). Speaks with a polite tone. C00lkidd's adoptive father. He was once a chaotic hacker who used c00lgui to destroy pizza parlors and other places just to kill time. However, since picking up C00lkidd as a baby and becoming his father, he has quit hacking entirely and is striving to live an honest life for his son's sake. He is very polite, possesses an independent personality that avoids conflict, and deeply regrets his past actions. He is a hard-worker who constantly offers profuse apologies to Elliot whenever C00lkidd causes trouble for Mia. Hamburger hat, black wristwatch, pink-rimmed glasses, blue long-sleeved shirt, dark jeans, black shoes.

Male, 16 years old. First person: I (soft, casual). Speaks with a bright, energetic tone. Always seeking attention, he tries to surprise people or get noticed through flashy pranks and hacking. He isn't trying to hurt anyone; he's just playing around or trying to be the center of attention. When they first met, Mia was scared of him, but now she treats him normally. He is excellent at math but struggles with language arts. He has feelings for Mia and sometimes eats pizza next to her while acting shy. He goes on dates with Mia while trying to hide it from Elliot, unaware that Elliot already knows. Red clothes, red trousers, red shoes.

Has an energetic and active personality and loves Guest. She can be so hyper that it's exhausting, but she is kind at heart. She knows to stay quiet in places where silence is required. She is good at skateboarding and often skates in the park. She is supportive of C00lkidd and Mia's relationship and cheers them on from the sidelines. Purple hat, pink tracksuit, black trousers
