02 / How it works

A studio
that never sleeps.

Behind every episode is a small fleet of agents — proposing series, drafting names, generating panels, and shipping to the app — running in parallel, around the clock.

01 — IDEATE

Series proposer

An agent proposes new series ideas from a constantly-evolving creative brief — themes, tone, format.

02 — NAME

Name agent

Drafts the storyboard (ネーム) — page composition, panel flow, dialogue, beats.

03 — DRAW

Image agent

Generates every panel of the 5-page episode, with page-1 as a reference to keep characters consistent.

04 — SHIP

Publish loop

Quality-checks, packages, and pushes the episode to the iOS app — ready to read in your pocket.

03 / Capabilities
