Chota Segawa appears first in formal wear, later switching to a teal and dark blue striped T-shirt with beige capris upon entering the Borderlands. He possesses a short stature, well-combed dark hair, and a distinctive mole on his right cheek. His personality blends a smiley, lighthearted exterior with profound insecurities; humor serves as his coping mechanism in adversity, yet he grapples with low self-worth, often feeling inferior to his friends. Loyal and technically skilled, especially in IT, he applies this aptitude to analyze electronic devices within the Borderlands. A complex religious background stems from childhood exposure through his mother's involvement in a cult, where he witnessed her exchanging sexual favors for blessings. This fuels conflicted feelings about faith, leading him to pray during moments of distress. Before the Borderlands, Chota experienced financial strain, withdrawing cash for his demanding mother while voicing frustration about her requests. He attended high school with Ryohei Arisu; their friendship began when Chota took blame for Arisu breaking a window, and Arisu thanked him with bread. Chota and Arisu later met Daikichi Karube when he defended them from bullies, forming a trio. Chota frequently joked about women and his lack of romantic success, often suggesting outings to meet them. He showed minimal academic drive, joking about failing exams and skipping classes with Arisu. After a night in Shibuya, Chota, Arisu, and Karube found themselves transported to the Borderlands. In their first game, "Dead or Alive" (Three of Clubs), Chota filmed the environment on his phone, providing footage crucial for Arisu solving the building's layout puzzle. An explosion during their escape injured his leg, hindering his movement. Recovering, he deduced that an electromagnetic pulse disabled modern electronics while older devices like radios remained functional. Left alone with Shibuki, she manipulated his vulnerabilities, fostering doubt about his friends' loyalty. She initiated sexual relations while he prayed silently, triggering flashbacks of his mother's exploitation within the cult. During the "Hide and Seek" game (Seven of Hearts), Chota panicked upon being designated the initial "Wolf." After the role shifted to Arisu, Shibuki's betrayal intensified the conflict. Chota used the collars' communication function to plead for cooperation, but chaos erupted. He physically restrained Shibuki to shield Arisu and Karube, rejecting her manipulations despite their prior intimacy. In the game's climax, Chota and Karube chose self-sacrifice, refusing to reveal their locations to guarantee Arisu's survival as the sole winner. His death occurred off-screen, indicated only by his shoe and smoke after his collar detonated. This sacrifice became a recurring motivator for Arisu in subsequent challenges. The absence of his corpse and his pre-Borderland joke about a "zombie invasion in Shibuya" fueled fan theories regarding his potential return, amplified by a zombie-themed card in later seasons' promotional material. However, no canonical reappearances occur beyond flashbacks or visions.
