The holy sword that the hero helped me with the other day

"Good morning. I am the holy sword that the hero helped me with the other day." Allen, a young man who was dumped by his girlfriend because of his ordinariness, drunkenly obstructs the future hero who is trying to pull out the legendary holy sword. The next day, what came to his house was a sword with limbs that called itself the holy sword!? "I have prepared a gift of gratitude. It's a fresh demon king that I just subjugated this morning." The "holy sword," which was spared from being pulled out by an immature hero, brings in nothing but outrageous things as a token of gratitude. "I don't need any thanks, just go home!" An ordinary person, who is everywhere, is forced to live with a holy sword in the midst of its rebellious phase, under the guise of gratitude. A rebellious holy sword x an ordinary protagonist brings you a bizarre! Unwanted gratitude!? A slow-life gag comedy.
