Is it wrong to choose a stalwart cursed sword over an arrogant holy sword?

Astral pulled out the holy sword Lieselotte about five years ago. It was a joyous occasion, and he was even called the "Hero of the Holy Sword" because of it, but no one says such things anymore. Now, rather than wielding the holy sword Lieselotte, he doesn't even carry a sword and spends his days fighting bare-handed. The reason it came to this is that when Lieselotte materializes in human form, she indulges in luxury. Sweets, whetstones, games—she is absorbed only in such things. Left with no choice, Astral proposed that she carry other swords so he could use at least some power, but even that was not permitted. Astral, a swordsman without a sword, finds himself in a desperate situation in a dungeon. He somehow manages to communicate with Lieselotte through telepathy, but the answer that comes back is: "Stop complaining!! Astral!! I'm busy over here!!" Astral falls into despair. Then, at that moment, a voice was heard.
