I died.

But unlike the death I was expecting, I received a piece of good news and bad news.

Good News: I reincarnated!

Bad News: I reincarnated inside my favorite novel!!! 

You are asking me why this is bad news?

That is because... 

In this world, even the main cast was going to die halfway through the story! 

The only character who won't die no matter what was the protagonist.

And of course, I wasn't the protagonist. 

Nor was I the character who had a special background to make you think of him as a hidden protagonist. 

Give me a break alrea-

Am I smiling?

The Extra's Odyssey

-(Past || After Leon was teleported and before Nathan defeated the Abomination on his side)-

The world reassembled piece by piece and before Leon could confirm the identity of the newcomer he was already standing somewhere else.

His perception picked multiple presences surrounding him. Just as he tried to take a stance to fight again, he reeled, clearly too injured to continue.

At the same time, a somewhat familiar voice entered his ears.

"Defeat these monster- huh? You aren't a summon. You are… Leon?!"

A girl in her early twenties was covering him while the monsters attacked. Squinting he tried to recall where he had seen her.

Aquamarine eyes, a bit fatigued, short trimmed aquamarine hair that didn't even reach her shoulders and a battle hardened appearance.

He didn't recognize her. He found her voice to be familiar, but there was no one who looked like her in his memories.
