I Transmigrated Into a Mecha World, and I Pilot Ultraman

I thought it was the kind where the protagonist traveled to a different world to become Ultraman, then concealed his identity and used a mecha to fight monsters. If the mecha couldn't defeat him, he would transform. I didn't expect it to be Ultraman Mecha, so I was a little disappointed. But come on author, it just doesn't suit my taste.

Unlike pure hand rubbing, it has an AI style

So-so, okay

Very good book highly recommended
