Description
Dorūshi, also known by the epithet Iron Wall, is a character who appears as a contestant in the tournament to decide the next Demon King. Physically, he is depicted as a tall, bald demon.

In terms of personality, Dorūshi is characterized as a caring individual with a notable fondness for chocolate and a general sweet tooth. As a finalist in the Demon King tournament, which selects the ruler of the demon realm, his combat abilities are highly respected, with his specialization being in defensive magic. His prowess in this area earned him the title of Iron Wall. His magical abilities are primarily used for defense, but they can also be adapted for offensive purposes, with one of his known techniques being Defense Bomber. Beyond his magical skills, Dorūshi possesses enhanced physical capabilities, including significant speed and reflexes that allow him to dodge attacks from awakened humans, as well as great physical strength, demonstrated by his ability to push an awakened human back several meters. He typically uses a staff as an aid in combat.

Dorūshi's role in the story extends beyond the initial tournament arc. He is a member of the Urum Castle Defense forces. During the Human Assault Arc, he is shown engaging in combat against a character named Edil. Later, during the Save the Humans Arc, he and the other members of the Urum Castle Defense are informed of a moving human tower and continue their work on a technique intended to save humans as a harsh winter approaches. When creatures from the New World begin attacking Urum Castle, Dorūshi is called upon alongside allies Theta and Liliabba to help reinforce the castle's defensive barrier. His relationships with these characters are primarily professional, fighting together as comrades to protect their stronghold. His development is shown through his transition from a tournament participant to a key defensive asset in the larger conflict against the awakened humans and the New World organisms, where his specialized defensive magic proves crucial for protecting others.
