Nekomaru Nidai is a character in Danganronpa 2: Goodbye Despair, and his title is the Ultimate Team Manager. Nidai is a loud and boisterous man who always is encouraging and supports his friends. He’s known to almost always be shouting or be loud when speaking, but it's partially due to him being a team manager and full of energy - he’s always down to spar with anyone as a form of serious training, especially with Akane. Though he has an extreme sense of willpower and optimism, he isn’t the brightest bulb in the shed, or the best actor when it comes to lying. He also doesn’t seem to have a sense of shame when speaking whatever is on his mind and can end up saying things that may make others feel a bit embarrassed or uncomfortable (mainly when discussing using the restroom), which Mahiru tries to keep him in check for. He also can get a bit too close in other people’s bubbles, but he doesn’t mean any harm and tries to keep his boundaries when someone tells him they feel uncomfortable. He also seems to be skilled in massages, self-proclaiming to be the Ultimate Massuse and is always offering to others if they’d like one of his “special massages” and claims it a “secret weapon” to relieve fatigue in an instant, while also feeling addictive to the receiver (which is seen with Akane and Hajime). So though Nidai has an extremely loud and aggressive personality and seems a bit scary at first glance, he does truly have a kind heart and is not afraid to express his emotions (especially not afraid to cry), and wants to support and protect his teammates and friends as much as he can, believing that a fighting spirit and teamwork are essential to him. Nidai is so protective of his friends that he’s even willing to sacrifice himself if he has to… even at the cost of his life.

As a despair, Nidai would coach/train people against their wills, without giving them any chances of a break or a moment to breathe. Eventually, these people would end up overworking themselves to the point of death by either heart attack, heat stroke, regular stroke, or anything else that involved heat, exhaustion, or stress. Being one of the strongest remnants in his group, he was also one of the “bodyguards” of the group, protecting his classmates from the future foundation and fighting them head-on (seen in Dr3 - Future Arc 1 alongside Akane as backup for Peko).

Not much to note about his voice; either one fits! Just looking for someone who’s REAAALLLY able to project and channel Nidai’s loud and boisterous energy!
