Koenma

As the son of the Spirit World’s ruler, this pint-sized official serves as the authority responsible for appointing Yusuke Urameshi as Spirit Detective. Despite his toddler-like appearance and constant use of a pacifier, the 700-year-old leader manages the judgment of souls between Heaven and Hell. While he often provides comedic relief through his cowardly tendencies, he remains a devoted ally during crises. His signature pacifier even stores immense energy, capable of unleashing the devastating Mafukkan defensive spell.
