Isekai Toushou no Maken Seisaku Gurashi

Lutz, an unlicensed katana smith, has created a stunning and perilously beautiful sword but cannot sell it due to his status. When his partner Claudia is taken by corrupt knights, he decides to use the sword for action. Meanwhile, Gerhard, a struggling enchanter, seeks a remarkable blade to inspire his craft and prove his worth. Both are obsessed with creating legendary weapons, each for their own reasons. Their paths converge as they pursue their respective goals, unaware of the consequences their combined efforts might bring. Whether their collaboration leads to greatness or disaster is uncertain, but to them, the outcome is irrelevant.
