Ibuki was an antagonist in the Meteor Festival arc and later a recurring character in the Murder Incident Solution arc in Beastars.

Ibuki is a Maasai lionin his mid-thirties. He was sold as hyperdrug material at the age of 12, but ran away, living alone the Black Market until he joined the Shishigumi at age 18. During his time in the organization, he always tried to get along with everyone and his boss; his desire was not to seek a high position, but to unite them as a family. This was not possible under the command of the first boss, who made him project an aura of oppression that made herbivores around him look at him in fear.
