Oni

An oni (鬼) is a type of spirit in the Shaman King series. They are typically spirits filled with negative emotions that eventually build up until they materialize and lash out.

Shaman can create oni-like beings called shikigami (式神) as a method of combating oni.

According to Alumi Niumbirch, Ike-Oni's power may surpass that of the current Shaman King, Asakura Hao.
