Zokingdog is a dog character clad in tattered rags. He undertakes a solitary journey to find his lost family member, Pipi-chan. While traveling through an unfamiliar city, he faces danger and is rescued by God King, a cockroach possessing a noble disposition. Following this rescue, Zokingdog and God King continue the search together.

Zokingdog is pure-hearted and earnest, yet prone to easy depression. Moments of extreme happiness cause him to faint. When overwhelmed by intense fear or profound sadness, he responds by singing, an activity he deeply enjoys. His behavior reflects emotional vulnerability coupled with expressive release through song.

His visual design consistently features ragged attire, mirroring his transient and challenging journey. His relationship with God King forms a central dynamic, contrasting the cockroach's positive outlook against Zokingdog's sensitive nature. This partnership becomes foundational to their narrative progression.
