Amanai, Yuu

天内悠

Yuu Amanai serves as an apprentice and endorsee of Yuujirou Hanma during the Maximum Tournament. Throughout the Maximum Tournament Saga, he acted as Yuujirou's comrade. Yuujirou encountered him in America, where Amanai was working as a bodyguard for the US president. The Ogre took him under his wing after Amanai kidnapped the president's attacker.
Amanai is a highly unusual and ambiguous individual. Outside the ring, he appears very friendly and seems to dislike unnecessary violence, but inside the ring, he becomes unpredictable and ruthless. In the first round of the Maximum Tournament, he kicked Minoru Yamamoto in the face and knocked him out, showing no concern for Minoru's life. Amanai ceased his attack only due to interference by the judges.
