Defense Devil is a Japanese manga written by Youn In-Wan and illustrated by Yang Kyung-il. It is serialized by Shogakukan in Shōnen Sunday since April 22, 2009.*
It can be argued that it is a manwha due to the ethnicity of its creators. However, like Black God, it is considered more proper to call it a manga due to the location of its publishers, its target audience due to the right-to-left orientation, and the definition of both terms that imply that the original publishing country of origin is a deciding factor. Do not contest over this in an edit war. If you feel that the need to start an argument over this, bring it over to the discussion page.

This manga provides examples of:
Aborted Arc: There is one instance where Schugarl is addressed as "Gary Peter Schugar" by Father Selma. It is never brought up again, nor is it even made clear whether it's an alias Selma merely provided for him or a hint at a former identity.
This could simply be the result of different translators romanizing his name differently, as Shugarl's first/last name is often spelled as Gelipeta. Taking that into consideration, Selma could have just known Shugarl's full name without any significant meaning behind it.
Genderflipped version with Jupiter and Shugarl, due to some confusion with the newly transformed women-to-men-shower room the little girl Jupiter ends up in the shower room alone with a very naked Shugarl. It's up to the reader to interpret what exactly she saw and/or understood due to the steam but the girl is still blushing long afterwards.
Accidental Unfortunate Gesture: A little girl that Kuccabara saves, Jupiter, gives him a cross which is deadly to demons as a thank you gift, and then leads him to the girls shower when he could not touch the cross.
Mr. Fanservice: Random girls on the street guess Shugarl is a model when he strolls down the street, some of the scanlation group are already his fans and he does give the female portion of reader a nice amount of fanservice.
Fire and Brimstone Hell: Every Hell is different, since every Shinigami gets to make their own version of Hell for the victims they bring back. This one is Maya's version.
Genre Shift: The series starts out as a court drama in hell with a demon fight near the end of every story line. Now it's a shonen fighting manga with a bit of ecchi. And is now sort of shifting back to court drama.
Good With Numbers: Shugarl is so good with physics that he can cause power lines to break by flicking away his cigarette the right way. Doing equations also allows him to attack people with his demonic abilities.
Hitman with a Heart: When tasked with killing Catherine (Idamaria), Selma simply can't bring himself to do so, and instead cares for her like she was his own daughter. This comes back to bite him in the ass four years later, when the church he served discovered the deception.
