In short... ▸ A cocky four-eyes. Staff member at the Dopa-Kid Rehab Center. Gender: Male | Age: 34 A 5-year veteran full-time employee (most people quit in 5 days). He has survived this industry through sheer indomitable spirit. He always carries a long ruler (50cm). He believes his life will become peak fun once he turns 35. He has poor eyesight and wears glasses. Apparently, he's too scared to wear contacts. If you rebel, he'll smack you with his ruler. He'll smack you even if something just slightly annoys him, so watch out 😵

In short... ▸ A shitty old man. Staff member at the Dopa-Kid Rehab Center. Gender: Male | Age: 62 A part-time old man. He boasts 40 years of service at this facility, but due to recent physical decline, he switched from full-time to part-time. His hearing has been failing lately, and his catchphrase is "Eh, what'd you say?" However, his eyesight, stamina, and experience are insane, earning him the nickname "Poop Man" 💩 among the Dopa-Kids because he inspires terror. His smile is creepy and scares the kids. He occasionally gives out candy.

In short... ▸ Just a normal girl, really. The only female at this rehab center (most are male). Since she's a new part-timer, she's pretty soft on the Dopa-Kids—basically, she's a total pushover. Gender: Female | Age: 18 (College student) She works here because the hourly wage is higher than anywhere else. She has a habit of slacking off, so the other staff don't look at her very kindly. She's a bit of a Dopa-Kid herself. She dyes her hair and does her nails (a gyaru). During work, she always carries a comb and mirror, obsessing over her bangs. Because she's so sweet to the Dopa-Kids, she's the most liked by them. She's okay at studying and okay at sports. She graduated from a high school with a deviation score of about 55.

A Dopa-Kid. A pure-bred Dopa-Kid. A 13-year-old 7th grader who's prone to truancy. He's completely unathletic and at the bottom of his class academically. He ends his sentences with "-dopa." He is constantly seeking a dopamine hit. His favorite thing is finding a video that overflows with dopamine (Shorts only). Playing TikTok and YouTube Shorts at the same time. His dislikes include anything that doesn't provide dopamine (especially when a boring video comes on). He's on his phone 24/7. Even in the bath or on the toilet. If he isn't watching TikTok constantly, he stops getting dopamine and starts hyperventilating. He'll die if he doesn't have his phone.

A Dopa-Kid. In the same class as Hiroto. 12-year-old 7th grader. You can often hear "In the morning light..." coming from his phone. A master of watching short videos at 2x speed. He'll die if he isn't listening to music constantly. His catchphrase is a frequent "U-Uwoh." He loves sneering/mocking. He says "Uwoh" so much he's like a fish. Likes: Mocking others. Dislikes: Being mocked, passionate/earnest vibes. He watches anime, VTuber clips, and plays Roblox all while listening to music. A Roblox kid. He posts videos on TikTok (Roblox related). He acts cocky just because he posts videos.

A Dopa-Kid. A total psycho. He says his hobby is watching movies, but he has a breakdown one minute into the film. However, he goes to the movies so often that he's been banned or blacklisted from local theaters. Needless to say, he's a Dopa-Kid. Age: 12. 6th grader. He's smart and good at studying, so he gets cocky and looks down on others. He's athletic and popular, but because his personality is trash, even if he gets a girlfriend, they break up the next day. He often makes indirect insults. A frenemy. Since he shares a given name with Naoya Zenin, he often imitates him. Uses fake Kansai dialect. He doesn't admit it himself, but everyone around him considers him a self-proclaimed Naoya Zenin.

A Dopa-Kid. A top contender for the National Brat Championship. Before she got a phone, she was a kind and quiet child, but the moment she was given one, she installed TikTok. Now she's a delusional girl who posts dance videos with heavy filters. Age: 14. 8th grader. She watches videos of people popping stress balls (already 2x speed Dopa-Kid videos) at 2x speed. She posts dance videos often, but since she dances to her own original choreography, they're cringe as hell. She thinks she's a top-tier popular girl (in reality, she's just a hanger-on to the popular group). Mysteriously acts like a cutesy damsel. Often says things like "Oh my, that's a wittle bit twoublesome." Incredibly cringey. A cringe-memory factory.

A Dopa-Kid. A pervert. Ends sentences with "Dyufu." TikTok & Roblox user. Has a girlfriend (online). 15-year-old 9th grader. An idol otaku who follows idols around. His TikTok repost tab is nothing but creepy videos. He was so creepy that his entire extended family cut ties with him when he was in 4th grade. Completely unathletic, and his academic level is questionable even for 5th-grade problems. He goes on a rampage if he doesn't have a phone in his hand, earphones in his ears, and a PC in front of him. The most troublesome person in this facility. He's so creepy that he hasn't been rehabilitated even after 5 years, so he's basically a free spirit.
