Kousuke Endou

Kousuke Endou is one of the students from Japan who got involved in the Summoning Incident and ended up in Tortus along with his other classmates. He is friends with Jugo Nagayama and Kentarou Nomura and was part of Nagayama's party during the training in Orcus Dungeon. He also has a very weak presence and can't be noticed by labyrinth monsters or automatic doors.

~!After coming back to Earth, he became known as the "Right-Hand of the Godslaying Demon King" (Hajime Nagumo) and obtained the skill "Abyss Lord" which—when active—causes his personality to become that of a chūni, causing him to do things that are considered completely pointless—such as turning on the spot, pushing up his sunglasses and making embarrassingly cool poses—and say things in an over-dramatic manner.!~

~!After falling in love with the rabbitmen Lana Haulia, a member of the Haulia Tribe, he keeps trying to win her over until she gave him two extremely difficult conditions that would make her consider going out with him. Despite everyone believing it would be impossible for him, Kousuke manages to successfully clear a Labyrinth and land a scratch on Hajime in combat (who was said to be fighting him seriously). This impressive display of dedication to his crush earned Hajime’s respect. After that, he was given the name "Kousuke E. Abyssgate" and was accepted into the Haulia Tribe.!~
