This is probably the best devil may cry amv I've ever seen.
For those who don't know Devil May Cry is a video game, but they made a short anime based off of it.
In the anime Dante, the main character, has to protect a orphan girl in the first episode. After that she starts to live with him and is in every episode.
Through out the anime they form a close bond, but in the last few episodes patty meets her mother, and she gets into a fight with Dante.
Dante almost dies fighting a demon (he has a sword thrust into his chest) and Patty cries because she never got to thank him for everything he's done for her.
