Ultraman from the Upside-Down Sea

A Letter from the Hanging Sea

Who exactly is the Ultraman named Nais?

Zero: "What's wrong with you? That impostor is way too weak!"

Etelgar: "I think Lugiel and I might have something in common."

Belial: "Just looking at your face makes me furious. I want to strangle you!"

Nexus: "... This kid could use some discipline."

Ailiya and Belial: "What? Never seen such a handsome (beautiful) Ultraman before?"

Nais: "Why do I keep jumping back and forth across worlds like that DCD guy next door?"

Senior: "The road ahead is long, junior. Keep it up!"

P.S. The chapters aren't continuous. The main story is interspersed with jokes, so pay attention as you read.

Theme: Power isn't good or evil. What matters is whether it's put to good use.
