I Was Ignorant and Joined the Holy Grail War for No Reason

"Looks like I'm in the nineties." Ye Chu, who had never watched anime at first, thought he had just gone back to the past. If he hadn't seen the magicians fighting, he would have always thought so. "No one told me that gas leaks were so serious in Japan in the 1990s!" In short, this is an unlucky guy and a lucky guy who keeps trying to escape but can't for various reasons. PS: Let's talk about the world setting here. This world is in a state that has been corrected but not fully repaired after seven levels of singular point repair. Although the world has been deformed, it is still usable. Because some essences are caused by deities of authority and detachment from the roots, many singularities actually have residual problems. And the original Yechu was the one who got the things left behind by the singularity after the seventh repair of the singularity, which made the current Ye Chu appear. Let's talk about the protagonist's state before acquiring the second identity: the protagonist has no memory of the original owner. Because of the side effects of animal husbandry, the protagonist has always been instinctively obedient to others, but because his instinct is more afraid of death, he sometimes breaks out of this state, so you will see that he is timid but reckless. Then Hermes is a parasite, not the original owner, but will be bound by business. Mercury is a liar, and he is not the original owner, but he was not born long ago. Finally, I would like to add that authority actually has side effects, but authority that is fully grasped will not have side effects.
