The Holy Sword That was Helped by a Hero the Other Day
"Good morning. I'm the Holy Sword you saved the other day." Allen, an ordinary young man dumped by his girlfriend precisely because he was ordinary, gets drunk and impulsively ends up interfering with the future hero trying to draw the legendary Holy Sword. The next day, what shows up at his house is a sword with arms and legs calling itself the Holy Sword!? "I brought a thank-you gift. A freshly slain Demon King, hunted this very morning." The "Holy Sword," relieved it wasn't pulled by an inexperienced hero, keeps bringing over the most outrageous things as repayment. "Forget the thanks, just go away!" An ordinary person gets stuck with a rebellious Holy Sword under the guise of repaying a debt.
