Written and illustrated by Gege Akutami, the manga delivers a much darker, fast-paced, and uncompromising narrative than traditional shonen.

Thorfinn, a young Viking warrior, seeks revenge against the mercenary commander who murdered his father.

For those seeking a deeper experience, Undress Tournament takes the core janken concept and places it within a semi-realistic, open-world 2D point-and-click adventure. In this world, battles are decided by rock-paper-scissors, and the loser undresses. Victory can even lead to sexual encounters.
