Is GoGo Monster Worth Reading? Review & Where to Read

Overview

Yuki is in the third grade, and he believes there's another world layered underneath his elementary school — one with its own residents, living behind a locked door on the top floor. As misfortunes start piling up around the school, Yuki becomes convinced the two are connected. He finds something like a friend in IQ, a fifth-grade math prodigy who wears a cardboard box over his head and rarely speaks to anyone else, while his classmate Makoto remains one of the few people who still treats him normally.

Taiyo Matsumoto, best known internationally for Tekkonkinkreet, wrote and drew this as a single, self-contained volume — a rarity for him, and one of the more compact ways into his body of work.

What it does well

The book's defining choice is also its best one: it never tells you whether Yuki is actually perceiving something real or experiencing a break from reality that the adults around him read as a developing mental health problem. Both readings stay live the entire time, and Matsumoto never tips his hand.

The art is doing as much storytelling as the script. Matsumoto's loose, nervous linework turns hallways, classrooms, and playground equipment into spaces that feel subtly off even when nothing supernatural is happening on the page — dread built through composition and texture rather than incident.

Yuki and IQ's friendship is the emotional center, and it earns that position. They're both kids the school has already sorted into a category — gifted-but-strange, troubled-but-harmless — and the book is quietly sympathetic to how little room either label leaves for an actual child.

For a creator whose best-known work runs long, this is a genuinely efficient introduction: one sitting, Matsumoto's full visual sensibility, and a real critical track record, including a Japan Cartoonists Association Special Award and award-circuit nominations internationally.

Where it falls short

The ambiguity that makes the book distinctive will read as a cop-out to readers who want the central mystery of the top floor actually resolved. Nothing here closes the loop, and that's a deliberate choice you either buy into or don't.

Even at one volume, the pacing is unhurried — this is a book built to accumulate atmosphere rather than advance a plot, and it asks you to sit with unease rather than follow a mystery toward a solution.

The supporting cast outside Yuki, IQ, and Makoto stays thin. Teachers and other students exist mostly to represent how the world treats kids like Yuki, which serves the theme but doesn't give you much to hold onto beyond it.

Verdict

GoGo Monster is a confident, unsettling mood piece that trusts its reader to sit with an unanswered question rather than hand them a tidy resolution. If you want Matsumoto's art and sensibility without a multi-volume commitment, or you just want a horror-adjacent story that gets under your skin without ever raising its voice, this delivers in a single sitting.
