Doseki Ganryū

is an Academy student of Konohagakure.

Personality
Like his classmates, he is quite curious and has watched princess Kae and Kawaki's behaviour with interest.

Appearance
Doseki is a very large boy with plump cheeks and gray eyes. He has short, curly brown hair, and the most prominent part of his appearance is his bushy unibrow. Doseki wears a green T-shirt and brown pants tied with black cloth.

Kawaki & Himawari Academy Arc
Doseki attended the Academy opening ceremony as part of a new class. His classroom was put under the care of new teacher Hana Kaka. His class included many children of famous people, including the daughter of an acting duo, the daughter of the Seventh Hokage, and Kae Yukiwari, the princess of the Land of Bamboo. The class also included Kawaki, a noticeably older student.

Later, a practice session was used for various competitions to teach the students how to work as teams of 3. Doseki was teamed up with Ran Sōgi and Yuina Itomaki.

When his class had to put a play about the Sannin, Doseki was part of the group who helped build the stage under Neon's direction. After it was damaged by Eiki's struggle with Kawaki, Doseki joined everyone in the repair efforts.

The day of the festival, Doseki helped his classmates set up the stands and decorations. When the festival received a terrorist threat, he stayed inside. Later, following Hana being hospitalised from the terrorist attack, Doseki joined his class in welcoming back their teacher.

To make up for the festival being cancelled, Hana arranged for the class to undergo survival training on an uninhabited island. However, Kikuchiyo was injured and their food supplies vanished, stoking fear about a rumour of killer missing-nin settling on the island. Everyone formed groups to scavenge food, and later to look for Neon's damaged drone. Doseki and Tao wanted to search the island, having the advantage of numbers, but Kawaki argued against it, pointing out how diminished their surveillance capabilities were. By night, everyone enjoyed their food.

Attracted by an explosion, the class encountered Kawaki and Himawari, who revealed that Hana, actually an assassin, had killed Kae. Himawari pointed out that her actions made more sense if Hana wanted to keep Kae as a hostage. Working together, the students tracked Kae and Hana to a cave. Finding the situation too dangerous for the students, Kawaki revealed himself as a shinobi, and credited them for helping find Kae. Eiki still believed there was something they could do.

As the class rushed to the docks, hoping to find a boat of some kind to get help, they were approached by Sai Yamanaka, whose team came to help after learning the truth about Hana. Upon finding Hana, she was already defeated by Kawaki and Himawari. As Hana decided to kill herself rather than be captured, she was stopped by the good personality inside her. As it was learned that Hana had a split personality disorder and her original self truly cared for her students, the students kept encouraging her to regain control, ultimately helping her break free.

Later, Hana was allowed to return to teaching with a seal in place to ensure her other personality couldn't take control again. Kae also revealed that she had to return home early to step up as leader of her country with her father having fallen ill. As a sendoff, the class performed their intended play from the festival. Later the train station, the class saw her off.
