Six men on the verge of their sixtieth year find themselves living together under one roof. This shared house, a kind of self-contained utopia, is populated by individuals who have seemingly abandoned their current lives. Within this enclosed community of men who have stepped away from the world, an unimaginable development is about to unfold. This is the starting point of Kanrekihime, a dramatic human story from creator Hiroya Oku that explicitly moves away from the science fiction battles of his previous works.

The narrative is centered on this group of six elderly men, each with a distinct appearance and background. The title itself, Kanrekihime, plays on the Japanese term kanreki, which marks the traditional celebration of a person's sixtieth birthday—a full cycle on the calendar. This suggests a thematic exploration of aging, identity, and personal transformation, focusing on characters who are at a major cultural and personal milestone.

The setting is a shared house that serves as a kind of refuge for these men. Described as a utopia for those who have given up on their current lives, the location creates an insular world where the central drama will unfold. The closed environment is likely designed to intensify the interactions and relationships between the six residents, forcing conflicts and connections that might not occur in the outside world.

As a narrative early in its publication, the specific story arcs are still developing. The initial arc establishes the premise of this unusual communal living situation and the six men who inhabit it. The core conflict emerges from the "unimaginable development" that disrupts this seemingly peaceful haven, though precise details remain under wraps. Given the creator's stated focus on a "drama human, without any battles," the tension is expected to be psychological and emotional rather than physical. Future arcs will likely delve deeper into each resident's past, the reasons they abandoned their former lives, and how the group confronts the mysterious event that challenges their secluded existence.
