I Transmigrated with My Friend's Character Guide

I hadn't even made it through the entrance of the anime convention when I turned around and saw the iconic five buildings.

Me: ???

In this world full of danger, only fanfiction can make me feel safe. And the various secret identities in those stories have become my golden finger for getting by in another world.

But is something wrong with the settings for these secret identities?

!!! I took my friend's character setting collection by mistake!!!

I am 0429, skilled in combat, a clone made in a laboratory, and a disposable tool worth 180,000;

I am Akutagawa Ryunosuke, seeking knowledge through my faith in Yog-Sothoth; I am Nakajima Atsushi, a domineering CEO who never goes anywhere without a three-piece suit;

I am Dazai Osamu, an angel who has lost his memory and is currently stranded in the human world;

I am Yukimura Seiichi, an executive of the Port Mafia;

I am Miyamura Izumi, a failed experiment;

I am Amamiya Ren, a lone wanderer of the night;

I am Nakahara Chuuya, the god Arahabaki;

I am Obsidian, adventuring in another world;

I am Enkidu;

I am Hyakkimaru;

I am Ryougi Shiki;

I am Fujimaru Ritsuka;

I am Kibutsuji Muzan...

#About how I only put on a disguise but people keep imagining my tragic past##These wounds are drawn on, so stop staring at me##I'm not tragic, stop imagining things##I told you not to dig into my settings, now look, you've made yourself cry##I'm not dead, but keep imagining things and I will be##I said these are just my friend's settings, why are you still imagining things#
