Harry Potter who almost starved to death his families ring teleported to him and slightly healed him long enough to escape the durslys and follow the wierd pulling the ring is bringing him he gets taken to a old Potter house that's almost destroyed opens a room finds a amulet that allows him to go to the Potter sanctuary
It holds all books potters have collected ever the good and bad potters
As the last of the line without any branch families he had to go there the especially considering he was starving to death
there is food and books Harry reads while feeling lonely
he helps block that feeling by reading books and doing enchanting/runes
One day when he decided to leave his manor for awhile only to stumble on a women half dead with 9 fox tails (yasaka pre kunou )
(Yasaka was there for a deal with the british royal family as they had a rare item she Kinda wanted but a faction in the Yokai used it as a way to try and eliminate her)
He sees her And decided to bring her into the potter manor to heal her she has memory loss but with her ability to turn into a fox she becomes his familiar
She has her motherly side and no memorys she gets glimpses from time to time
After the nara clan heard she was supposedly killed they got pissed and killed the faction that sent the hit and took over as leader
No one knows she's alive she will slowly regain her memorys but that won't be soon she can't use her power as she douse not know she has any
The story would follow Harry Potter till the end then go into dxd
Harry is self taught till sirus comes so his ideals are more align with the idea his Nobel family must grow and family first
Turning the Potter house from a light nobel house to a Grey one
Harry knowing he's the last Potter knows he has to have a harem / kids to rebuild it
Still embarrassed as hell over the idea
