昔取ったきねづかで…と言いながら無双する定食屋のおっさん、実は伝説のダンジョン攻略者

This old man is too strong, LOL

In a world where dungeons had suddenly appeared on Earth, a dungeon in Shinjuku, Kabukicho was said to be the most difficult dungeon in the country. Then, an unknown individual managed to conquer that dungeon. But the identity of the conqueror of the most difficult dungeon in Japan remained a mystery. Nearly 20 years passed just like that. 

Enter Kenichi Nishida, a 40 years old man who decided to quit his corporate job to open a restaurant in a certain area of Tokyo. However, his restaurant barely received any customers. Stuck in a predicament, Kenichi Nishida finally came to a conclusion.

“My restaurant might go viral if I start serving dishes by using ingredients sourced from the dungeon and post it on social media.”

Fortunately, he had some experience exploring dungeons back when he was a university student. Then, rumors started spreading. 

“There’s an old man claiming he uses minotaur meat that he personally defeated.”

“There’s no way a mere restaurant owner could defeat a minotaur.”

“What a blatant lie.”

However, he couldn’t make anyone believe him and he ended up receiving negative reviews instead. Outraged by this, he decided to livestream his dungeon exploration.

(This old guy is way too strong, LOL)

(Just what the heck is he?!)

(Plot twist. He’s actually a high-ranking explorer.)

“No, no. I’m just an ordinary restaurant owner. I just happen to have some experience doing dungeon exploring back when I was young. I do have to say, I’m quite confident with my skills though!”

(((THIS IS BEYOND THE LEVEL OF ‘QUITE CONFIDENT’!!)))

The livestream where he easily defeated not just a minotaur,but other low-level bosses in an instant quickly went viral worldwide. Furthermore, it turned out he was the unknown conqueror who had conquered the dungeon in Kabukicho 20 years ago…
