The Demon Bosses of Inyouchuu - Printable Version

A good story and hentai needs a good evil compelling villain, and Inyouchuu has a handful of them that might be nearly as iconic as some of the lovely ladies.

Nightmare - The iconic humanoid upright horsedemon. This demon lord proudly enjoys his nudity, hah. He is a very powerful yokai that tends to refer to the girls, even Mikoto, simply as "girl" and disposable after he's done torturing them in Inyouchuu's crazy sexual ways. Capable of putting them in a Nightmare on Elm Street styled dream state as well, to which the Shin Remake kind of implies they "feel" just as they would in reality. He's a poweful and very meticulous, merciless demon, with the annoying "Imp" grunt who does a lot of his bidding.

Too powerful for the girls and Yamato to even cleanly defeat, he is ultimately sealed up in the first stories main canon ending. But is he gone for good?

Spoiler

Nightmare's fucked just about all of them in the long run and got even more action in the Shin remake, which was amazing. Although kind of a standard big cock(s), it's still damning and big enough that it kind of pulverizes the insides of whoever he drills while he doesn't show any remorse.

Meioki - Meioki was born a lesser pathetic weak demon, that fed on souls and dead bodies. At some point many years ago, he corrupts and takes over the body of Ouka and Kikuka's own father. Making it even more personal how attached these three characters tend to be, him cursing them with regeneration abilities, so they can be tortured again and again in the most insane ways possible. In the OVA, it it showcased that he drains spiritual energy through sexual intercourse too. Whom our lovely white mage Sui has the most potential for, might explain why he takes such a preference to her.

Meioki's perhaps most iconic feature is having one of the most vile, disturbing, massive set of two mutant demon cocks that are all pokey and uneven, surely being some of the most painful insertions in the world of hentai. This was an interesting trick in his appearance of Shoku and Hanamaru 2, his cock looks so inhuman, that they didn't censor it. But they did in one of the Goku era DLC's, yet it's that classic modern hentai joke where his cock is so big, the stomach bulge so insane, what even is the point of censoring?

I believe in one of the best and possibly canon Shoku endings, he is dealt with by Ouka whom is extremely powerful when need be, even stronger than the other girls with her summoning capabilities.

I do love the joke that Meioki is a lolicon. He has sex with Ouka and Kikuka a lot, also with loli Takeru in the Shoku manga. Something I wished happened in the game with Takeru, or OVA.

Yamato - The perv joker himself! It is a pretty cool idea that this series' main male character is a half-breed and that the third game leans into it. Based off the OVA, the idea of the girls having to willingly please and mate with him to keep his darker energies at bay, is kind of cool. But how good did the Etsu game do it? I'm not really sure how to judge yet. CG hardcore level wise, Etsu is a lot tamer than the other games and is lacking Sui, Ouka, and Kikuka... so it's a funky one. But yeah the "ideas" could be cool.

Gyuki - I love that Gyuki is based off some Japanese yokai: https://en.wikipedia.org/wiki/Ushi-oni
I thought for sure there was a bit about this demonic entity being very gluttonous, perverse, and sexual... but maybe I made that up. He is one I'm more infatuated with overtime. It really takes the whole bug sex idea to the next level, featuring a car/tank sized massive spiderdemon that fucks the girls personally. Only in a sparse few scenes sadly, but the Mikoto one is one of my favorites. There is a lot of potential with him and some fan ideas I think.

His cock is some giant, huge censored brown thing that almost looks like it has a tongue, eyes, or something at the tip. But I think there's also potential that Gyuki's genitalia might be a bunch of tentacles too. There is one Rinko scene with one of the nastiest and coolest looking tentacles, I'm not sure if it's part of Gyuki or not... I think there's a chance. Maybe someone can confirm or it's in English someday.

Syuki - The orange brute oni. He is brutal, hulking and size wise gives the past humanoids a run for their money, probably the bigger cock in ways. Personality wise? I'm not sure I have much to report on him right now and my friends who played Goku, I can't recall how they described him. He has a few good scenes, I love the one with Rinko, and the one with Takeru is real insane cum inflation wise.

Mujyuurou... I ask, how was this guy not the main baddie of Goku? For my tastes, he's one of the best designs in the series. Just utterly disgusting in all the right ways. We don't see a cock shot but can you imagine how infested his weapons must be! I love that idea, even beyond tentacles, there are nasty demons like Mujyuurou here who ejaculate worms and bugs themselves...

These are some other interesting designs that didn't get much use either. The muscular bug faced demon is really cool as well.

Last but not least, giving the Mouryou no Nie mummy a shoutout. Don't even know his name, if he has one, but it's such a cool concept for a mummy with all bugs, centipedes, etc wrapped underneath. I'm surprised there wasn't a cameo or 2.0 version of him in Inyouchuu proper.

Well that went all over. What do you think of the Inyouchuu Demon Bosses and designs?

Now this is absolutely the level of lore trivia I was hoping our site would be cataloguing! I figure a lot of this stuff will eventually get copied and formatted for the wiki when I/we have time, but at this point I think we're already on track to be a great TinkerBell informational reference even without it.

Looking for a new avatar led me to this guy, who was in a pixiv post of a bunch of demons from an artist who worked on the Inyouchuu series, but who I can't another source for through google's version of reverse image search.

It was from a group post in 2016 with several demons who made it into Goku like the oni and Mushi.

On the plus side, if this guy didn’t make it into the games, that just makes him a free character to headcanon for ourselves!

That demon was in the Inyouchuu Kyou epilogue, I believe. It was a weak spirit surrounding a hot springs town, when it reawakens it goes straight to Kikuka/Ouka to become stronger. Also Rinko, Yamato and Sui are there. After they beat him, he gets reaal humble lol.

Well lonsesomebro is all about Kikuka and Ouka lately, I say the stars aligned haha.

When you say he gets humble, do you mean he meekly backed off, or is this a "Begs for mercy before getting vanquished" situation?
Because now I'm imagining him popping up after every job the Black Cats take like this:

"Soooo, did that mission tire you guys out?"
"...."
"Maybe exhaust you so much that you'd be helpess to stop me from taking your energy?"
"...."
"No? I'm getting a 'No' vibe here. I'm just gonna excuse myself then" Proceeds to squeeze himself down a nearby manhole opening

My new favorite couple...
That said I should put Goku era Takeru in there to be most accurate. Tongue

He begs for mercy haha. Can't remember if they let him go or not, but your interpretation of him is pretty spot on. He kinda reminds me of Meioki in a way. A weak demon trying to become the strongest, squid-guy is just way lower stakes and without Meioki's oni obsession. It was funny to see him like that after clearing the bed ends where he does the usual Inyouchuu treatment on the twins, goes from 100 to 0 in a heartbeat lol.
