Nekomaru Nidai is a student of Hope's Peak Academy's Class 77-B, and a participant of the Killing School Trip featured in Danganronpa 2: Goodbye Despair. His title is the Ultimate Team Manager. Nekomaru is a vigorous, boisterous, openhearted student who is passionate about supporting athletes, but suffers from dyspepsia. He frequently shouts when speaking, being a team manager. He is very optimistic and his willpower is immeasurable, but he isn't very smart and he's very bad at lying. He also really appears to enjoy fighting, often in the form of very serious training. Nekomaru sees no shame in talking about certain things that could make others feel embarrassed or uncomfortable. For example, he never misses a chance to loudly proclaim when he needs to go to the restroom, irritating Mahiru Koizumi, and causing him to apologize. He also tends to get too close to other people's personal space, though he does this just to check their potential as athletes. Furthermore, as the self-proclaimed Ultimate Masseur, he frequently offers his special massage to the others to the point that he forces them to receive his massage, as shown in his first and fifth Free Time Events with Hajime. He states that his massage is his own ultimate weapon that can relieve fatigue in an instant, but it also appears to be highly addictive to the receiver.
