Nekomaru Nidai

Nekomaru Nidai (弐大 猫丸 Nidai Nekomaru) is one of the characters featured in Super Dangan Ronpa 2: Farewell Despair Academy. He has the title of Super High-School Level Coach.

Appearance
Nidai is a tall, muscular man with black hair. He wears a white tank top under a black jacket, as well as blue pants and sandals. He has chains around his neck with a whistle hanging in the middle part, and emits a blue electric aura from his eyes. He has  two scars running from the top of his both eyes downwards in their own directions.

Personality
Nidai is a vigorous, openhearted student who is passionate about supporting athletes but suffers from dyspepsia. He shouts a lot but for his own reasons. He is close to Akane Owari and trains with her a lot.

Pre-Despair Incident
As a kid, Nidai was born with a heart disease which made him very frail to the point of staying in the hospital. There, he met a kid named Daisuke, who also had the same problem. Nidai noticed that a lot of people visit Daisuke, and it was revealed that he is a manager of a sports team. Sadly, Daisuke didn't manage to see his team's victory and there, and Nidai became inspired to become a coach and continue his friend's dream.

As a coach, he trained a lot of good players including figure skaters that can perform  6 revolutions per spin and tennis players that were able to turn an almost-win into a win with a total of 36 hours of playing time.

Island Life of Mutual Killing
Nidai became helpful in solving different cases, providing different information [e.g. when he was about to use the bathroom]. At Chapter 2, Nidai and Souda tied up Komaeda to avoid his plans to continue.

During Chapter 3, Nekomaru Nidai defends Akane Owari from an attack of Monokuma, and is hospitalized due to the severe injuries he sustained. He returns after the third class trial has finished, shouting on how he came back from hell and spouting different words, but his body was in such a terrible state that Monokuma transferred his mind to a cyborg

Also, Robo Nidai gave himself a lot of new random features:


 * 1) A sleep mode switch at the back of his head/neck.
 * 2) A radio clock that’s incredibly accurate. Comes with an alarm.
 * 3) He can dispense drinks from his eyes.

Akane and the rest were surprise to see Robo Nidai, and was even joked by Souda that if he can see what's inside of Nidai. He was murdered in the fourth chapter by Gundam Tanaka to avoid starving to death. His remains are used by Kazuichi Souda to create a mini version of himself to cheer up a depressed Akane.

Akane Owari
Nekomaru is close to Akane due to their desire to improve themselves physically. She was the most shocked to discover that he was a cyborg and was really depressed about his death. This led Kazuichi Souda to use some of Nekomaru's remains to create a miniature version of himself to cheer her up.
