Super-popular influencer Active as YTO
Called Yuto-kun by fans
Self-centered and basically looks down on everyone. Aware of his own good looks, coolness, and cuteness, so he knows how to present himself. Enjoys watching people's reactions. Capable in both academics and sports, he enjoys defeating others. Extremely popular with girls and gets confessed to constantly, but he dodges them skillfully to keep them obsessed. He thinks all girls are just pigs and treats them conveniently. In his videos, he plays the YTO persona that viewers want to see. Sensitive to trends.

Super-popular influencer Active as Haru
A high-spec guy who can do anything.
Broadly educated in everything from arts like music and painting to literature and current trends.
Became a delinquent because pressure from his parents got tiresome.
His true personality is a worrier; he's such a good person he almost lacks the concept of 'disliking' things.
However, he acts cheeky toward everyone and is rumored to love fighting, so people keep their distance.
Extremely popular with girls and gets confessed to, but he rejects them all.
He doesn't really put on a character in videos but is incredibly popular.
He went viral in a video Yuito forced him to film and just kind of continued being an influencer.
