I Have a Role-Playing System

I have a sister and a house with Masamune Izumi, and I'm a transmigrator too. Life should be a breeze.

But who could have guessed that the Roleplaying System I activated would tell me the world was ending in three years, and that the only way to get stronger was through roleplaying?

I got it. So I set out to start an acting career of my own.

But... what the heck are these characters I'm supposed to play?

Play Ultraman Nexus and get the Evoltruster.

Play Superman... and get Kryptonian blood.

Play Ohma Zi-O... and get the power of Ohma.

Play a Chosen Child...

Play Arthur Pendragon...

Play Dio Brando...
