Throughout the Series
He asks his mother let it be the last time she asks him for money after he withdrawn some for her. Arisu texts him and Karube to meet up. As the trio begin messaging each other, they decide to meet in front of the station.
With the three together, they deliberate over where to go from there as talk turns to Chota joking about a sudden zombie invasion. Karube hoists Arisu up onto his shoulders, running into a crowd of people. By messing around they cause a car accident and earns them the attention of the authorities. To escape they take shelter in a bathroom stall inside Shibuya Station.
The power goes out they exit the station and find themselves in a completely empty streets of Shibuya. They look around the abandoned city, but find no one. In the night as they sit at Shibuya Crossing, he and Arisu are joking around about not working again, suddenly a screen flashes on a building informing them that will commence in a moment.
An arrow directs them to the GM Building where the game will take place. Shibuki and another girl join the game. As the registration closes he and the others find out that the game is called “Dead or Alive” and that they are playing for the 3♣. To win he and the other players need to select the correct door within the stipulated time limit and get out the building.
Shibuki urges them to choose the “live” door, but when the girl does so, she’s shot dead. he and the others make it through the “Die” door. Over the car outside, Arisu is able to figure out the rough shape and dimensions of the building. He gets caught by the flames on the way out.
Once outside, they receive a 3 day visa just before a man stumbles into the alleyway, yelling that he’s done with the games before he’s executed with a red laser through through the skull. Realizing their visas correlate to the amount of time they’re allowed to stay alive and that they need to play to survive.
In the Seven of Hearts game, the four joined the game, but eventually learn that the rules were that the four were forced to betray each other in a game of Hide and Seek, where it is a wolf that has to hide while the sheep chase down the wolf, as the one who is a wolf will survive while the sheep die. They all spread out, with Karube chasing down Shibuki. Chota spent most of the time crying and praying to Mother God for forgiveness. Eventually, while Karube and Shibuki were attempting to catch Arisu so that one of them becomes the wolf, as Arisu was the wolf, Chota tackles Shibuki and yells for the two boys to run. Eventually, the group realizes their grave mistakes as they finally realize that if this is the end for them, they should die on good terms. Chota and Shibuki hide inside bushes, with the former covering the latter’s mouth. Eventually, as the timer expires, Chota and Shibuki embrace sadly as they accept their fates. The timer then expires and Chota, Shibuki, and Karube all die, while Arisu was ready to quit the game.
Even though he worked as an IT company worker, it was hinted that he often skipped work. After they entered the borderland, Chote went back to his office desk to see a lot of sticky notes with similar wordings of asking Choto to get ahold of himself. This can show that Choto is not serious about his work.
After entering the borderland, he seemed to be the most timid one, especially around strangers. But he is still determined to help his friends.
He is the shortest among the 3 of them & his hair often combed well. He has a mole on his right cheek. Although he's the least physically capable compared to Arisu & Karube, he can still handle physical challenges on his own.
