After the Summon Failed, I Used Green Onions to Beat the King of Heroes

Traveling through time and becoming the most useless magician apprentice in the Fate world, his summoning ability is worse than industrial waste? At the beginning of the Holy Grail War, others summoned King Arthur and the King of Heroes, but I couldn't even summon a single soldier! Just when Cu Chulainn was about to send me home with one shot, my abstract summoning system finally came online—— Summoning Hatsune Miku riding a motorcycle with a green onion? ! The Noble Phantasm is the Onion Song? Can you make a legendary hero dance on the spot? ! "You mortals have no idea what abstract art is!" From then on, the serious Holy Grail War turned into a large-scale sand sculpture scene. I used instant noodles to summon Ramen Man Naruto, used my membership card to summon Barber Gilgamesh, and used my diary to summon Avenger Luffy... No matter what traditional magic or noble blood, they are all younger brothers in the face of absolute abstraction! This novel and its characters are purely fictitious.
