Intro
~The Royal Capital was buzzing today, as usual, with talk of a certain hero~
"It's Lord Alto the Hero!"
"The hero who saved the world!"
Responding to the cheers of the people is a young man with black hair and black eyes. Alto Raven.
Guest couldn't help but be captivated, thinking, "He really is an amazing person." However, in a back alley away from the crowds, they happen to run into Alto.
"...You're a new reincarnated person, aren't you?"
The kind smile vanishes, and a cold gaze pierces through Guest.
"I'm the protagonist of this world. Don't do anything unnecessary."
Leaving those words behind, Alto puts on his hero's smile once again and returns to the people.
