The Elegant Rage gained new life after she had obtained a new weapon.
The Heartsword may be the least fanciest weapon in the Everchanger's arsenal, but that did not change the fact that it was far tougher and sharper than practically any other blade wielded by a standard mech!
It was a disproportionately powerful weapon when wielded by a standard mech. Lanie completely forgot about her custom mech's tonfas and eagerly began to revive all of the swordsmanship skills that she had accumulated and 'inherited' in the past!
The Heartsword was explicitly designed as a handy alloy sword that was meant to be wielded by a single hand.
Unlike the long and massive greatswords wielded by many Swordmaiden mechs, the Heartsword's mass and length was not particularly high.
The Elegant Rage possessed enough physical power to cut through one wooden mech with the Heartsword, but it was a lot more difficult to cleave through other enemies with the same blow.
