Savage Hero

 
 R18 Fantasy mangas are relatively common in the present Japan pop culture industry but there is another one that is slightly cut above and caught my attention. This particular manga is called Kichiku Eiyuu which is translated as Savage Hero in english is another one of those Isekai Power Fantasy manga with a healthy dose of fanservice. Isekai manga with Mary sue protagonist is pretty much common by this time, but Savage Hero had it the main character superpower is literally being an incubus who gains and grants power depending on the waifus he slept with.

As expected from its Kichiku moniker, Savage Hero is yet another manga that is heavily influenced from Rance series. Having Waifu Power Up through physical intercourse trope is a dead giveaway. Savage Hero provides a glimpse of what sorts of Fantasy Adventure that Demon King Rance would have before he lost his sanity in Isekai format. The story itself so far are not particularly special but Savage Hero's Mangaka is another one of those Top Notch talent who are equally skilled at depicting extreme violence and ecchi stuff. 

Savage Hero setting could have been a very Grimdark one as humanity have many opponents to if not for the presence of the main character who is literalled overpowered enough to literally wipe out monster hordes by himself and save the day. While the future of Savage Hero is rather uncertain as the manga got axed once, Savage Hero is still an amusing read while the show last.
