Mahori Tsuchiya (土屋 真堀, Tsuchiya Mahori) is the Drill Banchou. One of the strongest fighters within the Dark Student Council, Drill Banchou is a fairly well-rounded Banchou with a unique set of tools and skills. His left arm is equipped with a drill which he uses for close-combat fighting and his right has an excatavtion machine that adds edge to his fighting style. Despite working for the Dark Student Council, Drill Banchou is a very honorable, friendly, and relaxed person who likes children.
Tsuchiya makes his first appearance after Gamu Kishiri's defeat, rescuing him from Haruka and Akira Kongou. He later shows up as part of the island destroying team, barely avoiding a trap set by Yuu Akiyama before fighting, and losing to, Haruka Kodama .
He has a crush on Haruka and retains it even several years later at her wedding in the final chapter.
