I recently found this new manga and it seems to be an interesting one to follow, mostly because I also have done a manga story related to the Nephilim. But this is quite an intriguing take on the Nephilim as it has taken on the biblical concept of angels intermingling with women as recorded in Gen. 6:1-4 and made it into a kind of action/adventure story about a sole Nephilim fighting for mankind (unbiblical of course, but still an interesting read nonetheless). However, I should warn you that it is violent and gory, and it has minor foul language. I do not know in what direction this author and artist will take their manga toward since it's only one chapter nor do I know if the author/artist are Christians themselves, but if it becomes too explicitly gory, sexually suggestive, and/or morally ambiguous, then i recommend as a Christian to drop this manga. Otherwise, I recommend to follow this manga for now
