Connecting to Kallen, I Lose My Memory and Become Omega Ultraman

[System + not invincible + growth and evolution + broad Ultraman perspective + mapped to the world of Tiga]

Oh my god! Ultraman!

Jiang Cheng has lost his memory. He now has a Galactic Security Force System, but it's extremely aloof.

At first, nobody pays attention.

Then more and more people witness monsters and Ultraman, and they realize a massive upheaval is underway.

Wait. Jiang Cheng looks at himself. Why does his face, after turning into Ultraman, look exactly like the one on TV?

Could I be Ultraman Omega?
