The DC Universe Begins with Ultra Armor

I've been transported to another world! My birthplace is a rice paddy, and there's a giant figure floating in mid-air with glowing eyes right in front of me. What's going on? I'm in a real hurry, waiting for some kind of cheat code online—Gero Kent, who just transmigrated.

This book will feature:

'Don't run, charge towards Ultraman's Flying Kick!'

'Titan will only waste my youth'

'Ultraman, do you really love this world that much?'

'Do what you believe is right.'
