So even now Kunishige was pretty hesitant with his career path up until he learned of what happened. Makes sense that he wanted Chihiro to understand the weight of making swords.
Great, we back to square one: enchanted blades. Those dead sorcerers probably can be saved if there are some wielders mixed with the team. If only the previous owners were not assholes. What a waste of good fighting power.
I hope not. This is much better than the earlier arcs, long may it last.
Btw Chihiro has Soga blood, and I doubt they were gonna come up with Kurotsuchi just to show it once. Either Chihiro or the sword nazi will use it once they lose their link to the blade is my guess, and Chihiro seems more likely.
