I’m the son of SATAN??

A simple fanfic that comes with the MC replacing Rin Okamura after the death of Father Fujimoto.
Rin will change quite literally and we will see how as the story unfolds.

[A/N: I am new to this writing thing and this is my first fic. Please help me correct my mistakes and be ruthless with me, I wish to improve everywhere I lack as a writer, though I don't qualify to call myself that as of yet. But please.... Onegaishimasu~]

Note: I don't own the characters nor the cover...
I'm just writing a fic. and the cover was awesome, so I kept it, if artist-san wants it removed, please say so, and I will comply.
