Sōta Sarushiro is a circus worker who is the suspect of a murder. He was the actor who portrayed Global Hero Onyankopon during the Hero of Heroes Grand Prix in 2018. At some point he quit his job and went to work for the Berry Big Circus. He has a shy personality and acts like the Three Wise Monkeys however it was shown that he also had another side of him that he had hid from Miles Edgeworth and Regina Berry.

Early life
Sōta was the son of a chef, Yutaka Kazami. He knew his rival, Isaku Hyōdō, and became a close friend to his son Naitō. Their fathers collaborated in a dessert making contest. However, Hyōdō betrayed Kazami and threatened his own son to make him tie Sōta up, so that he couldn't help his father who relied on Sōta to taste desserts for him. Naitō, crying and asking for forgivness, bound his best friend's wrists and legs. They were then both locked in a car outside in the freezing cold. The door froze over and they couldn't escape.

They nearly died, but the assassin Ryōken Hōinbō happened to pass by and rescue them. Meanwhile, Kazami killed Isaku and fled the country, leaving them both as orphans. They were taken to the orphanage Happy Family. They had also lost their memories from nearly dying in the cold.

Later, Ryōken was assigned to kill the president of Zheng Fa close by their orphanage. He killed him and the president was replaced by an imposter. Sōta witnessed the whole crime and drew a picture of it.

The group who ordered the assassination was going to betray him and kill him, but Sōta recognized Ryōken as his saviour. He saved his life by informing him of the group's betrayal. From here on, he would be treated like Ryōken's son. He didn't want to become "a weak person who could get murdered" so he wanted to follow in Ryōken's footsteps.

Sōta remembered the day he was tied up and locked in the car, but his memory was muddled. He mistakingly believed he was Hyōdō's son, and that Naitō's father killed his father. He decided to have him killed as revenge, thinking that if he hadn't stopped him and tied him up, "his" father wouldn't have been killed.

Accused of murder in prison
Sōta was held into police custody when he was a suspect of the murder of Manosuke Naitō, apparently his "close friend". Although not guilty for his murder, he was indirectly responsible for it. He made it look like Naitō was one of Ryōken's subordinates, knowing that it would lead to his death. Furthermore, he knew that Miwa was part of the group who betrayed Ryōken. Sōta was also the one who gave Naitō the idea of faking an assassination attempt on the president.

He also abducted Kay to the top of the Prosecution Investigation Committee Headquarters to frame her which would lead Miles Edgeworth to the true culprit responsible for the murder that happened there, Bansai Ichiyanagi, and reveal his illegal activities. He wanted revenge for his involvement in the assassination of the president of Zheng Fa.

A fitting end
"Tateyuki Shigaraki"

- Didn't you hear what he said? "It was all me." There's no doubt. He's a man who cannot trust others.

He completed his revenge when he finally killed their leader - the imposter posing as Teikun Ō. He had originally hired an assassin to do it, but he was thwarted by the president's bodyguards, so Sōta took the matter into his own hands. He met him by chance and killed him from his balloon. After Edgeworth exposed Sōta as the killer, the aforementioned assassin arrived to kill him, but was stopped by Ryōken.

Design
Sōta has long, reddish-brown hair that forms two bunches from behind. He wears a pink sweatshirt with a zipper that only zips down to its pocket. He also wears a light blue shirt that bears the insignia of Global Hero Onyankopon. He wears blue shorts and pink shoes. Later on, he wears a clown uniform while wearing makeup on his face with two pink tears painted below his eyes.
