Matsumoto created the manga behind Kaiju No. 8, following a man in his thirties working in creature disposal who acquires the ability to transform into one. The premise's strength is its protagonist's age: he is a failure by the standards of the genre he is in, and the story treats that as its actual subject.
He worked for years on series that did not find an audience before this one, an experience that maps directly onto his protagonist's position. Japanese monster cinema supplies the creature design vocabulary, and workplace comedy supplies the structure, with the defence force treated as an employer with recruitment procedures and internal politics.
Recurring subjects: late starts, adults competing against people a decade younger, and heroism treated as a job with an application process. His creature designs are grotesque and specific, and his action pages are unusually clear about scale, which matters in a story where the enemies are enormous.
His manga became one of the most widely read serialisations on a major digital platform and was adapted into an animated series with a large international audience. Its protagonist's age has been widely noted as a deliberate departure from a genre built almost entirely on teenagers.
For readers who want monster action with a protagonist old enough to have regrets. Suited to anyone approaching the animated adaptation, and to those who like creature design taken seriously.
