He wears a green jumpsuit with a pair of goggles attached to its hood, an equally green belt and outer pockets, and dark green sneakers. He also wears a yellow hair clip on the left side of his head. His sleeves and pant legs are rolled up, showing the white inside of the suit. A black leather strap with a metal buckle on its end comes from each goggle of his hood.

 * On August 14th in Mekakucity Actors, he wears a black shirt with a red neck underneath his jumpsuit and shoes that appear almost black. He changes to his regular outfit on the 15th.


 * At the end of Summertime Record, Seto is seen wearing a yellow shirt underneath a new white hoodie, which he wears with its sleeves rolled up to his elbows, along with the pants part of his green jumpsuit. He ties the arms of his jumpsuit around his his waist during this appearance.


 * In Kagerou Daze -in a day's-, Seto wears a short-sleeved green button-up shirt over a pair of dark blue (likely denim) overalls, which he wears with its bib down and legs rolled up to his knees to reveal its brown interior. He wears green socks that match his shirt and brown sneakers that match the interior of his overalls.

Personality

 * Seto is a kind-hearted person that gets along well with others. When he was a child, he grew up without parents and had trouble understanding others. His only friend ended up being a stray dog, which he later tried to save from bullies. That event lead to both of their deaths and Seto's encounter with the Kagerou Daze, where he gained his eye ability. Not long afterwards, he and Kido were assigned to Room 107 of the orphanage together because their eye abilities disturbed everyone else, and Kano joined them not long afterwards. Seto, who still grieved over Hanako, frequently cried and got in trouble with Kido for speaking politely to her.


 * Because he had difficulty controlling his ability, he would frequently and accidentally read others' thoughts and emotions. This continued even after he was adopted by Kenjirou and Ayaka Tateyama and became part of the Mekakushi Dan, which was founded by Ayano. One incident causes him to run from the city, which he found to be full of dishonest hatred, to the forest, where he meets Marry and, with his eye ability, learns of her loneliness. In the Music Route, he even learns of his and his siblings' deaths by the Snake of Clearing Eyes. In all Routes, he decides to befriend her  and take her to the Mekakushi Dan.


 * About three years before the start of the series, Seto decided that he has to become stronger and takes on part-time jobs to do so. Currently, he works as a florist at a shopping center and has other jobs, such as traffic control and delivering newspapers. Seto lives with Kido, Seto, and Marry in an apartment that also serves as the Mekakushi Dan hideout. He often wanders off to explore new places. Since learning how to control his eye ability, he has expressed disliking using it on people and will only do so when necessary. Instead, he uses it most frequently to understand animals and communicate with them.


 * In the current day, he is much more cheerful and has achieved his goal of becoming physically strong. He is very loyal to the Mekakushi Dan, as he will obey Kido's commands without much hesitation and will physically sacrifice himself to protect them from danger without much hesitation. In the Novel Route, he faces extreme survivor's guilt over their deaths but pretends that nothing happened for Marry, who has also been pretending to have forgotten about them. The stress of his emotions and being reminded of his lost loved ones eventually causes him to lose control of his ability for the first time in years.

Eye Ability

 * Stealing Eyes (目を盗む Me o Nusumu): Seto's eye ability allows him to hear the thoughts of others, includes animals. However, animals cannot necessarily understand him because he cannot speak their language. When he loses control of his ability, which he often did as a child, he can hear the true thoughts and emotions of everyone, even strangers, in a wide area. When used to its full potential, it can read a person's memories and even their experiences from past Routes.
