Kaze no Stigma: Kouen no Miko, Crimson Grave Recommendations
As I read Crimson Grave it reminded me of Kaze No Stigma, the characters and plot is very similar.
Kaze No Stigma & Crimson Blade:
-guy is shunned from clan/group
-accompanied by someone from the group/clan that shunned them
-had someone special to them killed before their eyes
-companion is strong and uses a sword
-guy is perverted (not a huge pervert like Tomoki from Sora no Otoshimono though -.-)
-both contain fighting and magic genres
If you enjoyed reading one of these mangas I highly recommend that you read the other. Although Crimson Grave is still publishing, Kaze no Stigma also has an anime adaptation if you are interested.
