Joganki belongs to The Third, a group marked by a red third eye granting technological interfacing and communication abilities. As a ruling technocrat, he wields significant political power within their hierarchy and enforces the "technos taboo," limiting human access to advanced technology.

He maintains a focused interest in the protagonist, Honoka, monitoring her movements and journeys. This extends beyond surveillance into active courtship. Simultaneously, he investigates the enigmatic traveler Iks, driven by doubts about Iks's origins and motives.

A pivotal event involves his capture and imprisonment by fellow Third member Rona Fauna. This stems from their past connection; Rona Fauna developed feelings for him after he showed her kindness. Her imprisonment of Joganki is fueled by jealousy and her own deteriorating mental state, aiming to isolate him from Honoka.
