Well you said you are going to include Oda Nobunga so how about making Aston forget everything when he returns to the throne and when he get's summoned again and he gets married/settles in a relationship. So we can make certain person life more sufferable considering this is Fate this isn't too much right? After all she has done too much damage to Aston it is only fair right?
Bow of the sacred spear goddess ? Fate great order Camelot ??? Namoral just stick the mc in FGO, it will be a marvellous. And to make it better, add her to a harem of artorias. That's it, since we're all Artoria simps, more than one is wonderful. We will have artoria alter, artoria goddess, artoria lancer, artoria fairy, artoria maid alter, artoria x, artoria x alter,.... was it all ??
