After experiencing multiple worlds and finally coming to terms with his inner self, Lin Mo initially planned to continue his lazy life in Type-Moon. However, he inadvertently summoned Metatron, also lazy, but in the Ruler class. Just when Lin Mo thought they could just watch the Holy Grail War and nothing else mattered to him, he was unaware that his current worldline had been sealed off by God because of him. (Those interested can read the prequel in my other book, but forget it if you're not interested. Because the beginning wasn't mainstream, but I didn't want to give up, I skipped the first two volumes and started over with the last three, jumping straight into the exciting climax. The flow remains the same: Type-Moon > Hell Inn > Warhammer.)
