Yu Yu Hakusho (1992)

S01E02 Koenma Appears

Guided by the lively Botan dressed in pink, Yusuke steps into an unusual realm known as the Spirit World. Here, he encounters Koenma, a 700-year-old ruler who has the appearance of a toddler, complete with a pacifier! However, there's little time for humor as Koenma presents Yusuke with a daunting challenge: to revive his life, he must hatch a Spirit Beast.
