Renga Kokubō

is a genin from Konohagakure and a member of Team 25.

Appearance
Renga has messy black hair with shaved sides and dark-coloured eyes. He wears a sleeveless brown shirt and brown shorts.

Academy Entrance Arc
On the day of the entrance ceremony, as everyone began looking for an absent Boruto Uzumaki, he suddenly appeared, crashing a train into the Hokage Monument, which left Renga amazed at his antics.

Later, his class was assigned by Shino Aburame to shadow a non-shinobi workplace to better understand its lifestyle.

School Trip Arc
Renga and his class went to Kirigakure for a field trip, where they were greeted by their tour guide, Kagura Karatachi.

Graduation Exams Arc
During the graduation exams, Renga was knocked out by Konohamaru Sarutobi, alongside Tsuru Itoi and Hako Kuroi, leaving all three of them unconscious. Later, following Boruto's plan, they were able to eliminate the other proctors and face Kakashi Hatake to take the bell from him. Despite their group assault, Kakashi easily repelled all the students. This however proved to be a setup to get the Sixth Hokage in a group String Light Formation. Despite their effort, Kakashi was still able to hold them off. Ultimately, time ran out with no one getting the bell. However, Kakashi still chose to pass everyone as they succeeded in the test's true goal; teamwork and loyalty. Later, he was put on Team 25 alongside Hōki Taketori and Hako Kuroi.

Byakuya Gang arc
With the continued thefts performed by the Byakuya Gang throughout Konohagakure, Team 25 was assigned alongside the other genin teams to help stop the self-proclaimed noble thieves. However, the genin were not permitted to engage the Byakuya Gang without aid from a chūnin or higher-ranked shinobi.
