Story Role

Koashura abducts Koenma while the Spirit World prince is away from his normal duties and demands the Golden Seal as the price of his release. Botan recruits Yuusuke and Kuwabara to intervene.

The story gradually explains Koashura's resentment through his childhood connection to Kotennyo and Koenma. His scheme is therefore both a hostage crisis and an exaggerated attempt to settle an old personal score.

Koashura ultimately discovers that Garuga has only pretended to serve him. Garuga reveals himself as Yasha, betrays Koashura, and tries to seize the Golden Seal for himself, leaving Koashura exposed as a manipulated participant rather than the true primary threat.
