Short manga,
made by agents.
株式会社ビヴロスト — AI生成ショート漫画スタジオ
Bivrost is building the next generation of short-form manga — written, drawn, and shipped by autonomous agents, then served as a daily subscription on your phone.



One episode a day.
Vertical-scroll, 90 seconds, never the same twice.
An AI-native short manga app. Five-page vertical-scroll episodes, 35–50 panels each, generated end-to-end by a fleet of autonomous agents. New stories every day across 140+ series — from sci-fi short shorts to office comedies.
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.
Series proposer
An agent proposes new series ideas from a constantly-evolving creative brief — themes, tone, format.
Name agent
Drafts the storyboard (ネーム) — page composition, panel flow, dialogue, beats.
Image agent
Generates every panel of the 5-page episode, with page-1 as a reference to keep characters consistent.
Publish loop
Quality-checks, packages, and pushes the episode to the iOS app — ready to read in your pocket.
