Yuichiro Takiguchi (滝口 優一郎, Takiguchi Yūichirō) is a minor character in Battle Royale.


Nothing about Yuichiro's background was known. If Yuichiro was anything like his novel and manga counterparts, then he would've been an otaku and extremely naïve.

Friends and Enemies[]

Yuichiro's only known friend was Tadakatsu Hatagami; he may have had a crush on Mitsuko Souma.

Before the Program[]

Before Kitano resigned, Class B decided to take a day off and skip school, Yuichiro included; he attended the basketball game against Class A, and celebrated when Class B won. Yuichiro decided to go on the class trip; while on the bus, he most likely chatted with Tadakatsu. Yuichiro fell asleep after breathing in a sleeping gas pumped into the bus; he was then transported to an island and fitted with an explosive collar.

Yuichiro, along with the rest of the class, woke up in a classroom in the island’s school. Unnerved by the presence of Shogo Kawada and Kazuo Kiriyama, Yuichiro rushed over to the window to watch a helicopter land in front of the school. Yuichiro was shocked to see that Kitano had returned. When Kitano asked the class if they knew the BR Act law, Yuichiro kept quiet, obviously knowing the law, but afraid to say it aloud. Yuichiro was horrified upon seeing Masao Hayashida's corpse. When Fumiyo Fujiyoshi was killed, Yuichiro panicked and ran for the door trying to escape before running towards the back of the classroom when the soldiers began firing. When Yoshitoki Kuninobu's collar got activated, Yuichiro ran around the room trying to evade him.

When Yuichiro's name was called, he grabbed his school bag and ran towards the front of the room; he caught his supply bag and ran out of the school.

During the Program[]

Sometime before Noon, Yuichiro managed to meet up with Tadakatsu and they later ran into Mitsuko. It is visually implied that Mitsuko seduced the two boys and then killed them as they are both naked and they are seen mutilated and she is seen getting dressed.
