How it connects to Blue Archive: the game and anime
Blue Archive began as a free-to-play mobile RPG developed by NAT Games (now Nexon Games) and published by Yostar in Japan. The game’s setting — the academy-filled city of Kivotos — provided fertile ground for spin-offs like Problem Solver 68, which explores smaller, character-centered stories that don’t always fit into the main game’s narrative flow.
Blue Archive’s popularity extended beyond the game: Blue Archive The Animation, the TV anime adaptation, premiered in April 2024 and brought additional attention to the franchise and its ancillary manga. The anime’s North American debut with English subtitles followed in May 2024, introducing the world of Kivotos to a broader international audience.
Differences between manga and game storytelling
- The manga leans into short, episodic adventures perfect for comedy beats and slice-of-life warmth.
- The game uses longer mission arcs, character progression mechanics, and event-driven storytelling tied to gameplay.
- Problem Solver 68 focuses on the interpersonal dynamics of a small team, offering character depth that complements the game’s roster-driven narratives.
Characters to watch
At the heart of this spin-off is the Problem Solver 68 team: a colorful quartet whose chemistry sells both the humor and the occasional heartfelt moment. Led by self-styled Outlaw CEO Rikuhachima Aru, the group’s mismatched personalities create comic friction that drives the series. Kaede Nogiwa’s art emphasizes expressive faces and kinetic paneling, underscoring both the jokes and the action scenes.
Buying and reading the manga
If you prefer collected editions to serialized web chapters, the compiled volumes are the best route — the fifth compiled volume arrived in September 2025 and collects multiple chapters, including key scenes from the final story arc. For serialized pages and author updates, Comic Growl hosts the original web installments; the official platform remains the primary source for the manga’s initial releases.

Why this spin-off matters for fans
Spin-offs like Problem Solver 68 serve multiple roles: they expand the franchise’s lore, spotlight fan-favorite characters in new settings, and provide light, low-barrier ways for newcomers to enjoy the world without needing to play the full game. For fans of Blue Archive’s character design and humor, this manga hits the sweet spot — it’s fast, funny, and full of personality.
Appeal beyond the core audience
Because the series emphasizes character-driven stories, it’s accessible even if you haven’t played Blue Archive. The comedic setups and clear character beats make it easy to enjoy as a standalone gag-driven manga, while easter eggs and nods to in-game lore reward players who are already familiar with the game.
Final thoughts
Kaede Nogiwa’s Blue Archive: Problem Solver 68 Business Diary is a joyful, character-focused spin-off that complements the broader Blue Archive franchise. Whether you’re a longtime player drawn in by familiar faces or a newcomer looking for a fun slice-of-life manga with action elements, Problem Solver 68 delivers consistently entertaining chapters and a satisfying conclusion to its serialized run. With collected volumes available and the original web serialization archived on Comic Growl, now is a great time to dive into the misadventures of the Problem Solver 68 team and enjoy a lighter side of Kivotos.
