The Soul Penetrates the World of Mechas, and I Drive Ultraman

Unlike pure hand rubbing, it has an AI style

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.

So-so, okay

Very good book highly recommended
