The Tragedy of Maria Renard (Maria X Yandere! Richter)

Hey guys! As a little treat for Valentine's Day, I was inspired by "The Tragedy of Chateau Cepage". If you don't know the melody, it's--- OKAY! I won't spoil it for you! Sorry! Again, it's inspired by the song and I hope you enjoy this little "Nocturne in the Moonlight" and "Nocturne of Recollection" twist.
There may be a potential PV that'll be paired up with this story!!

Few reminders before you go into the tale...
1) Maria doesn't know Alucard possesses vampiric nature yet still loves him.
2) Richter and Maria aren't related and don't know each other by ANY means.
3) Alucard and Richter don't know each other by ANY means.
4) Richter's still a vampire hunter!
5) Maria isn't a vampire huntress but a noblewoman.
6) Alucard is a Pureblood vampire, NOT dhampir.

NOTE: I don't own anything except for my take on the song. All rights belong to personal owners. Plus, I apologize for how late this is! I was working on another story! DX Thank you!
