Danmachi: Forging Swords in the Dungeon City

Waking up in a run-down and falling apart smithy, a young boy wakes up with two sets of memories; Albert, a young avid anime fan and Senji Muramasa, one of the greatest blacksmiths to ever live.

Faced with this confusing and world-shattering discovery, Senji turns his head and spots a tower that pieced through the clouds standing in the distance, something so majestic that ordinary humans could never dream of building.

But this tower was familiar to Senji, not from his own memories but Albert's.

"Danmachi, huh..."

A smile suddenly marred Senji's face as he processed what such a world actually meant, the memories of a young boy who idolized adventure and a swordsmith who had reached for a sword unreachable with human hands, practically jumped at the notion of embarking on an incredible adventure and even forging a sword on a divine sword.

*Disclaimer*
The first few chapters may feel a bit blocky as I was still trying to decide how I was going to write the MC's personality, it gets better after chapter 10 after I had figured everything out.

Also, MC is not reincarnated with Senji Muramasa's template, he's both his past lives combined!

Finally, MC will sometimes act like an old man sometimes and put things off.
