Fate: as a Passerby, Being Invincible Makes Sense.

I thought I could retire. As a result, I woke up in Fuyuki City, 1994. A golden light fell from the sky, and seven groups of heroic spirits and masters were already in place. The Holy Grail detected my existence - after the class column reported errors thirty-seven times in a row, a line of judgment that no one could understand popped up: [Parameter anomaly, not classified, recommended to avoid] The Holy Grail advised me to avoid it. But I looked at the heroic spirits with swords and swords in the night sky, at the Masters whose faces were serious as if the whole world owed them money, and at the golden-haired man standing on the telephone pole as if the whole world belonged to him—— Couldn't help but laugh. "No, are you fighting so seriously? It's just the Holy Grail War, it's not the end of the world... Wait, is it really possible that it's the end of the world?" "That's more interesting." I bought a can of coffee and sat on the railing of the Fuyuki Bridge, watching the two heroic spirits fight under the bridge. One of them noticed me, frowned and threw a red gun at me. I held the tip of the gun between two fingers. "Brother, your shooting skills are not good." From that day on, there was no peace in the entire Fuyuki City. Not because the Holy Grail War is too dangerous. It's because I'm too bored. ---
