Mikael transmigrates and discovers that he has arrived in the Nasuverse, a full two hundred years before the Fourth Holy Grail War, the one he knows best.
As a Dead Apostle, he resolves to make the most of his advantages and become the Nasuverse's legendary swordmaster, kicking the Counter Force and punching Kischur Zelretch Schweinorg.
Two hundred years pass just like that. During this long stretch of time, he finally realizes the truth: as a Dead Apostle, you should just sleep obediently and stop indulging in wild daydreams!
[Pure Type-Moon story. I'm not very good at writing blurbs. This book includes Mahoyo, Fate/Prototype: Fragments of Sky Silver, an original prequel to FGO 2.6, Fate/Zero, Kara no Kyoukai, Fate/stay night, Lord El-Melloi II, Tsukihime, FGO, and more. Other Type-Moon works may also be added.]
[There is a lot of source material, and I may get details mixed up, so I hope all you Moon Cell experts will be understanding if you spot any mistakes.]
