Kabru カブルー
Young human and the leader of his own party. He explores the dungeon together with Rinsha, Mickbell, Kuro, Daia and Holm. He was raised by his mother only. His main goal is to prevent the dungeon from expanding and destroying the nearest villages, which happened to his home village in the past and led to his mother's death.
On the surface, he has a rather laid-back and relaxed personality, but in the times of crisis, he becomes very serious and even merciless due to his strong sense of justice. His hobby is observing and analyzing the ever-changing relationships and stories of the other parties, which he considers the big part of the history. He is especially interested in Laios' party because of its unusual members. Thanks to his analytical brain he knows his party member's behavior very well and is way more capable of leading the team compared to Laios. He is also very manipulative and takes advantage of it.
Throughout the series, it seems like he is considered very handsome among female characters.
