Fate/Usurper

A teenage girl reincarnates as a Matou with little memory of her actual past, stuck in a holy grail war that's definitely not a part of canon, she must figure out how exactly she's going to survive without proper magecraft. -- First novel so keep that in mind when reviewing. Also, suggestions and criticisms are always welcome. -- I don't own anything from Fate/ the Nasuverse besides my OC. Cover picture found on the Battle Arena Amino.
