Read Introduction Auxiliary chapter first:

『Synopsis』:

Eryndor Retsu and Minamijuuji Sei.

Two friends with two odd names. And as fate would have it, these two average Japanese males would be summoned to another world.

"Please slay the Black Winged Supreme Ruler and the Demon King!"

...a kingdom asked.

Oi, oi, isn't that asking for too much?

In a world where terrifying creatures that can one-shot the planet casually take a stroll, and a goddess who has control issues.

You would expect these young teenagers to act like your average Shounen protagonists.. 

Unfortunately though.

『Congratulations!』

[You have triggered the ‘Pre-Extra: Goddess Scenario.’]

[Rank: Ex]

[Special modifications and alterations have been made due to ???]

[Objectives: ???]

• [Reward: ???]

Our protagonist happens to be someone who should not be included in the Goddess Scenario, but he soon finds himself the target of a sick Goddess's plans.

"Look! Another Wild Anomaly Has Appeared!"

Anyway, since I'm pretty much lost on what to do for my other book, this happened. 


Not the best of ideas, but to avoid getting burnt out, I'm doing this purely for fun.


I'll also try to explore other themes I don't have the leisure of exploring. 


And as a long-time fan of YNLB, what better way to celebrate the anime release than with a fanfic of it?


For some reason, I've been trying to continue my previous work, but it isn't coming.


No matter how much I try, I haven't abandoned it.


But for now, since my restless hands want to write, this happened.


Introduction to Yasei No Last Boss Ga Arawareta


For the longest time, I've loved this work, long since before it began its adaptation.


I've been keeping up with the manga, and I've read parts of the light novel. I know the major events, and so on.


I love this work especially for its comedic yet serious plot.


Because, like, have you seen the web novel chapter titles? One can get a vague sense of what the author is trying to do.


For some, it might be boring as hell, but I love it.


Especially the concept of the series.The low tiers are Wall level and Superhuman.


Level 300's are Large Town level and Supersonic+ in speed. Level 800's are Multi-Continent level and Sub-Relativistic in speed,


while level 1000's are Small Planet level, and Sub-Relativistic+ to Relativistic in speed.


Ouroboros and those who scale to them are Brown Dwarf level. Level 3000's are Solar System level and Immeasurable in speed.


Level 4200's are Multi-Solar System level. The strongest characters are Outerverse level+.


Of course, we can't have a character hitting Outer by chapter 100, right?


At some point in this fanfic, MC gains [Exgate] and accidentally connects it to an Outerversal Hierarchical world beyond the YNLB's.


Since [Exgate] does exactly that regardless of the level, it's plausible.


And the fact that MC is an anomaly should solidify this.


So, yeah, aren't you interested in seeing what overpowered characters like Ruphus, weakened Alovenus, Orm, and the MC would do in other worlds?


Just a silly idea that popped into my head, and now I'm sold.


So, join me and our weird adventures of,


Oh, before I forget, I might introduce some OC's to formulate MC's adventures.
