How will a guild of 41 all-powerful heteromorphs change and influence the events that happened in canon, while also creating entirely new events to explore? For you, the dear reader, this is a tale best told as a theory, a theory on godhood.

"Why strive to be a millionaire when you can be a god?" AU Self Insert(SI).

What if one of the supposed "Shitty Devs", one who dedicated his entire life, sacrificing himself to the work of developing YGGDRASIL is ressurected to the new world as his special avatar?

Four guild members are transported to the New World. To some, it was the best thing that could have happened to them, to others, it meant leaving behind everything that they once loved.

Reincarnated and twisted into an NPC…while YGGDRASIL is still running…trying to retain my fading humanity while being a demon of the Lemegeton…slowly gaining control over this new body as the final day of YGGDRASIL gets closer…and this?—THIS!—WHAT IS THIS!—LUUCIIIIFEEERRR YOU BASTARD!

Being transported into an anime is one thing. Being transported into a highly dangerous anime is another. I mean, yeah I'm gonna have some fun, but really? Here of all the anime's? I'm gonna really have to be careful with my future decisions. What the HELL am I an NPC of all things? Goddamnit!

Evileye has died. She expected darkness and oblivion, not reborn in 22nd-century Japan, a place far worse than hell. What else can she do but try to live in this godless place? At least she found a friend, an office worker named Satoru Suzuki. Let's hope there are no more surprises in her future.

This time around, when Yggdrasil finally shuts down, Momonga isn’t alone- Thank goodness, having his older sister around should hopefully make this whole situation much easier, and not infinitely more chaotic. Rated T for occasional swearing and gore. NOT A ROMANCE.
