Manosuke Naitō is the personal bodyguard of Teikun Ō, the president of Zheng Fa. He is present during the president's address to a crowd upon his arrival in Japan. When the president is injured by a bullet from an unknown gunman, Naitō immediately proceeds to secure the area. Later, Naitō also tries to stop Miles Edgeworth's investigation.

The invasion of Shelly de Killer
When Shelly de Killer infiltrated Ō's bodyguards in disguise as another bodyguard to kill the president, he nearly accomplished his goal. When the bodyguards try to stop him, de Killer incapacitated Naitō who became no help to the president. The head of security Gai Tojiro then thwarted and injured de Killer, which only made Naitō's rivalry with him much worse. After this event, Naitō was forced to wear a neck brace.

Involvement with murder investigation
Naitō was seen during the president's speech along with his partner, Tojiro.



Design
Naitō has a stripe of yellow hair that runs down from the top of his head to his neck that resembles a horse's mane (as well as that of Luke Atmey). He wears a formal black suit, with a light-blue shirt under a brown and beige checkered tie. He also wears a golden pin of the shape of a palm on his lapel as well as a neck brace, and carries a standard bodyguard's earpiece/headset on his left ear.

Personality
Naitō is flamboyant and loves to play with his gun. He is a skilled at twirling it around his finger and even goes as far to point it at people he talks to. He is also an avid player of chess. He is very envious of Tojiro and wishes to be the head bodyguard. He is also a man not to be trusted as proven when Ō realized too late to trust him with the fake assassination plan. His only (misplaced) friendship seems to be with Sōta Sarushiro.

Name

 * "Naitō" is the Japanese romanization of the word "Knight", and "Ma" (馬) means "horse", which both refer to his love of the game of chess, especially the Knight piece, which he resembles. He often compares himself to a Knight in the game of chess, defending his king.
