Heavy Metal by Kuropon

Daoist Inkdrunkwanderer's review — Heavy Metal

Ok so I won't lie....the premise didn't hook me at first.
A living suit of armor as the protagonist sounds like one of those concepts that's either going to be surprisingly brilliant or collapse under its own gimmick. Thankfully, Heavy Metal belongs firmly in the former category.

At its core, this is less a monster evolution story and more a story about growth, identity, and becoming something greater than what you were created to be.

Rusty, our protagonist, is a living suit of armor born from the strange fusion of a fallen Hero and a defeated Demon King. He begins almost like a newborn.....confused, ignorant of the world, and completely alone. He doesn't understand who he is, why he exists, or why the world would consider him an aberration. Watching him slowly learn, adapt, and carve out a place for himself becomes the heart of the story.

What surprised me most is how charming the novel becomes.

Rusty's early dungeon survival is genuinely fun. His attempts to use traps, poisons, and clever tactics often feel more engaging than simple power progression. Sometimes his plans work. Sometimes they fail spectacularly because he forgets things that seem obvious to everyone else. Since he's literally a suit of armor, concepts that humans take for granted don't always occur to him, which creates some genuinely entertaining moments.

The true stars of the story, however, are the Hero and Demon King.

Their dynamic elevates the entire novel. The bitter hero and the seemingly carefree demon king act as unwilling surrogate parents, mentors, and commentators throughout Rusty's journey. Their interactions provide both humor and emotional depth, and many of the best moments in the story come directly from their chemistry.

The humor deserves special mention as well. Rusty's nonverbal communication through emoticons should not work nearly as well as it does, yet somehow it becomes one of the most endearing aspects of the novel. It's far more expressive than the usual monster-novel growls and noises that plague the genre.

The worldbuilding unfolds gradually rather than through massive lore dumps. There isn't some grand cosmic plot immediately demanding your attention, but there are enough mysteries...particularly surrounding Rusty's origins, the Hero, and the Demon King...to keep you invested.

That said, the story isn't perfect.

The pacing can feel uneven early on, and readers looking for a clear overarching objective may find themselves waiting for the larger narrative to fully emerge. Some may also struggle to connect with Rusty simply because he isn't human. There is an inherent emotional distance when your protagonist is, quite literally, a walking suit of metal.

Yet somehow, despite all of that, the story works.

By the time the world begins opening up and the cast expands, I found myself far more attached than I ever expected. Not because the premise was flashy, but because the author executed it with far more heart than most stories in the genre.

If you're looking for a monster evolution story that focuses on growth, clever survival, memorable companions, and an unusually charming protagonist, Heavy Metal is absolutely worth a try.

Just don't judge it by the cover...or the armor.

The armor had more personality than half the protagonists I've read this year.
