“	After all, making new friends... It's spontaneous. A coincidence that happens to turn out right.	”
—Seto to Marry, Kagerou Daze, Chapter 23: Kagerou Daze VI

Kousuke Seto (瀬戸 幸助 Seto Kōsuke) / Seto (セト) is the second member of the Mekakushi Dan.

He is the foster brother of Kido, Kano, and Ayano Tateyama and also Marry Kozakura's first friend.

Appearance

Seto is a tall young man with short black hair and hazel yellow eyes. 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.

When he was young, he wore a purple button-up shirt, a white hoodie, golden brown trousers and purple sneakers.

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

Often smiling, Seto appears reliable, hard-working, and sociable. He has a deep fondness for nature and as such is seen having casual conversations with animals. Seto seems to have a strong sense of responsibility over the others and is very loyal to the Mekakushi Dan, as he will obey Kido's commands and is willing to put his life in danger for them with little hesitation. However, this appears to have a more depressive component to it, as he will perceive himself as a failure if anything goes wrong, regardless of whether he has any control over it. Though brave in the face of danger, he can get embarrassed or overwhelmed more easily than others and will physically flee if emotionally pushed too far.

In contrast, as a child Seto had trouble understanding others and was prone to crying at every inconvenience. He was apologetic, timid, and lacked courage; he felt that everyone hated him, a feeling solidified by his lack of parents and constant bullying from others. His only friend ended up being a stray dog, Hanako. His personality remained similar after he was moved to an orphanage, where he was roomed with Kido and Kano. There, he frequently got in trouble with Kido for speaking politely to her.

After meeting Marry, Seto decided that he wanted to become the kind of person who saves others from despair. To try to overcome his cowardice, Seto started taking on multiple part-time jobs about 3 years before the present day.

Since he initially couldn't control his ability well, he would often accidentally read others' thoughts and sometimes even their emotions, which more times than not were negative. These instance often overwhelmed Seto to the point that he would try to "run away" (i.e. flee) from the thoughts, which would cause trouble for his foster family. As such, to the present day Seto hates using his eye ability for anything besides communicating with animals. Despite this, he is willing to use his power for the people he cares for, shown as how he uses it to understand Kano in both the anime and light novel route.

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.

Trivia

• He has a pet hamster named "Hanao". Another hamster appears in Manga Route 2 that is the leader of all the animals in the forest by Marry's cottage and knows of Azami, but it is unknown if this is also Hanao in this Route.
• His favorite type of girl is someone like Yachigusa Kaoru.
• Like Kido and Kano, he is referred to with his last name rather than his first name.
• His white hoodie was a gift from Ayano when they were younger, but he gave it to Marry upon meeting her.
• He usually ends his sentence with "-ssu", a way to shorten desu, a Japanese polite copula.
• Because Seto has a lot of part-time jobs, he was designed to wear something comfortable to work around, as suggested by Sidu.
• His dog's name was "Hanako".
• Seto's designs had to be corrected the most when the anime production team presented the rough character sketches. According to Sidu, he looked like a whole new character.
• Shounen Brave's PV implies that Seto, likely in all but the first Route, learned with Stealing Eyes that meeting Marry would lead to his, Kido and Kano's deaths.
