The Last Sovereign Wiki
Welcome to The Last Sovereign WIki!

Game Summary

The Last Sovereign is an adult fantasy RPG that plunges you into the saga of a world torn between forces of lust and purity. As you enter the complex conflict, you forge a new path that will change the course of history!

...maybe. The thing is, acting like most heroes gets you killed, and most evil overlords' plans make no sense. The Last Sovereign is a game that twists your expectations for adult games, while fully embracing a reconstruction of some familiar old tropes to provide a lot of fun, sexy content.

Current Content

By telling a story that has sex as an integral component, The Last Sovereign offers a deep storyline that naturally includes sex scenes. No need to grind for hours or lose to every enemy to find the content. Not only will you adventure in a world where sex is a weapon, you'll build a harem of fully-realized characters with their own reasons for being with you... in and out of the bedroom.

Fan descriptions:

Just downloaded this game today, and holy crap it is outrageously well written. The protagonists are all brilliant: their banter is pitch-perfect and effortlessly endearing. I'm used to finding characters in porn games attractive (that is, after all, the point), but I don't think I've ever grown to like them before. I'm seriously blown away by the characterization. Plus, the plot is actually interesting too! Oh yeah, and the sex is hot... the writing is so evocative, the scenes are easy to picture. Just... wow, kudos.[1]
I'll be really honest here: I haven't had much fun playing games, of any kind, for ages, and it has really left me frustrated, because gaming has always been a big hobby. From the world building, to the dialog, to the characters, I’ve really gotten into this game a lot. The sexuality is handled with what can only be described as a frightening amount of maturity. I love the fact that as important as sex is in this game and world, that the game doesn't FEEL pornographic. I love the fact that the characters have emotional bonds and reasons for being, even characters like Yarra and Qum. The quality of the writing, and the fact that the game is so much more than a vehicle for sex scenes, really make it a stand out piece. I can't quite gush enough how much I enjoy it, as a game, as porn, but also as overall fiction.[2]
Honestly, this is one of my favorite adult games. Intelligently written, humorous, and characters with realistic motivations (for their world anyways). And I loved going through the school library, both for the glimpses of the world building process and for the character comments about the books they find. Having succubi as a major race on the world rather than a summoned demon is a twist I've not seen elsewhere but it adds depth to the game, and lust magic gives interesting mechanics without breaking the general JRPG system. I do recommend that people play other adult RPG Maker games before playing this one, just so you can recognize the parodies that are going on, and the roads being deliberately not taken. Having played some Harem Collector lately, the contrasts are particularly strong with that one. (I think both games have their place, but if you like plot instead of just "plot", then The Last Sovereign is for you.)[3]
This game is pretty good, mostly complete, has a number of fetishes, and definitely belongs here. There's a number of corruption/control style points to it. No it's not your average wham, bam, let's have sex type thing. I highly suggest it, it's one of my favorite games now ... the story telling is that good. All I can say is it's rather well written and I think challenges a number of standard plot/story ideas. I can't recommend it enough. I found it by accident and am thrilled that I did.[4]

Enjoy the humor, do a variety of quests (no basic broom fetching), use custom mechanics, visit different countries, find secrets... but overall enjoy a compelling story, unforgettable characters, and more in The Last Sovereign.

Download the game

The public build can be found at the development blog; there may be a newer one for supporters on Patreon!

There are two versions of the game package (with no difference in gameplay):

  • Lightweight version: Requires RPG Maker VX Ace RTP to be installed. If you find that confusing, use the RTP-integrated version instead.
  • RTP-integrated version: Larger file size but self-contained and portable. Has niche uses such as playing from a USB drive or on machines where you don't have permission to install the RTP.
