I think rather then complaining we should enjoy his hardwork and help these unknown groups to find better cleaners so they can do a much better job next time. I hope they also don't drop this manga like one time scans.
How a weapon from a lvl 6 got broken by defeating a lvl 5 when wielded by a lvl 2? So far when he uses Argonaut every weapon gets smashed, so he would lose Hestia Knife if he were to use it.
In the series, there is a special enhancement that can be forged into super high quality gear/weapons called "Durandal." Gear with Durandal are "invincible" and can never be shattered/broken; however, they still get dull and need sharpening using special materials every now and again. Bell's knife a.k.a. Hestia Knife has the Durandal enhancement because it was forged by Hephaistos herself. Bell's Argonaut ability is pretty fucking OP when fully charged and most any weapon, outside of those with the aforementioned Durandal trait, will be severely damaged by the force generated.
Thanks for the translation again man...
This seems like the MC has now become awfully powerful with all these one time abilities but active is better than passive so... it's not that much good...
