Momonosuke

Momonosuke is an inhabitant of Wano Country and the son of Kin'emon.

It is revealed in Zou Arc that Momonosuke is not actually Kin'emon's son, but rather the son of Kouzuki Oden, the previous shogun of Wano Country, before he was killed by Kaido in an alliance with Kurozumi Orochi, the latter who would become the new shogun.

In chapter 1051 Shinobu used her Ripe-Ripe Fruit to ripen Momonosuke's body into that of an adult.

Following Kaido's defeat and Orochi's death, Momonosuke revealed himself to the citizens of Wano, taking his rightful place as the true shogun of Wano Country and undoing all of Orochi's despotism.
