Yeastken (いーすとけん) is an adorable character series created by Kamio Japan in 2017. The name combines "yeast" with ken, meaning dog in Japanese. These fluffy, bread-like dog hybrids secretly live in bakeries, hiding among the freshly baked goods. Each Yeastken has its own personality and bread-inspired appearance, but they are generally gentle, laid-back, and fond of food. They spend their days relaxing, playing, and trying their best to avoid being discovered by bakery customers.
