UBAI Ending is the third and final installment in Studio Ubai's nukige visual novel series. Once again, we follow Ryousuke Iijima, an employee of Ubai, an adult video production company that secretly operates a business specializing in arranging affairs between married women and clients with NTR fetishes.
This time, Ryousuke begins exploring relationships outside his usual work assignments, becoming involved with Shizune Hiiragi. Meanwhile, he is also tasked with approaching Kasumi Fujishiro, another married woman who eventually becomes involved in Ubai's activities. As these relationships develop, Ryousuke starts questioning his future within the organization and discovers more about its inner workings.

Unlike previous entries, this installment places greater emphasis on Ryousuke's personal development and the relationships surrounding him. It also brings back familiar characters and explores the history and future of the Ubai organization, giving the series a proper conclusion.
The game features 2 distinct story routes, although one of them is not available from the beginning, as it works more as an additional story or an alternative scenario to the main narrative.
In the main route, Ryousuke takes drastic measures against Studio Ubai, ultimately choosing to leave the organization and move on with his life. The secondary route can also lead to this ending, but its main appeal lies in exploring the opposite possibility: what would happen if Ryousuke decided to remain with Ubai? In this alternative scenario, both heroines become fully involved in the studio's NTR activities, eventually leading to an uncontrollable series of sexual orgies.
Another important detail worth mentioning is that the game includes a free DLC accessible by selecting the **Zero** option when launching the game through Steam. This is a short alternative story that shares the same premise as the main game but features an entirely different cast of characters, providing some additional content for players looking for more NTR-themed scenarios.

As a traditional visual novel, the gameplay revolves around reading dialogue, following the narrative, and experiencing the different character interactions. There are only 2 choices throughout the entire game, so there is no need to maintain multiple save files or deal with complicated branching decision trees and there are no substantial gameplay mechanics beyond the usual visual novel format.

The game features a total of 27 sexual scenes (excluding scenes that only involve kissing), although some are variations with slightly different dialogue but largely reuse the same CGs. This brings the number of genuinely original scenes to approximately 20.
As for their quality, it is decent overall. The artwork is nothing particularly impressive, but the character designs are good, and both heroines are attractive, with appealing and erotic body proportions. However, the coloring is rather simplistic, with very little use of shadows to emphasize their curves. Artistically, it also lacks the distinctive visual style often associated with NTR titles, which tend to feature dirtier, more detailed, and visually exaggerated artwork.
On the positive side, all sexual scenes feature Japanese voice acting of good quality and are completely uncensored, allowing you to see both male and female genitalia. Unfortunately, the anatomical details are relatively basic and lack the kind of realism found in more detailed adult artwork.
Regarding sexual fetishes, if we set aside the NTR theme that is always present due to the game's premise, there isn't much variety worth highlighting. Most encounters are relatively vanilla, featuring vaginal sex, oral sex, and some anal sex. The more fetish-oriented content mainly consists of threesomes, 2 VS 2, gangbangs, triple penetration and orgies.

Overall, the game isn't bad by any means. It runs without noticeable issues, features decent artwork, and offers a good amount of sexual content. My main disappointment lies in the narrative, which simply wasn't what I expected from the final installment of the series.
I have mixed feelings about this final installment in the series. Although Ryousuke is technically the protagonist, the real appeal of the premise was always the idea of a studio dedicated to corrupting and exploiting married women, pairing them with men who enjoy NTR, and turning those encounters into a profitable business. I would have preferred to see this concept pushed to its limits, exploring a storyline focused on expanding the operation and organizing increasingly elaborate orgies, rather than one where Ryousuke attempts to "regain his humanity." As a result, the NTR content takes a backseat, and the overall experience feels considerably more vanilla.
That said, if you've followed the series and want to see how it ends, this is still an enjoyable title. Furthermore, the inclusion of the free DLC makes it feel almost like getting 2 games for the price of 1, providing additional material for a satisfying late-night session.
Ultimately, whether you're interested in seeing the series reach its conclusion or simply looking for a decent amount of uncensored adult content at a reasonable price of $12, this is a worthwhile option to consider, especially if you've already picked up the best releases of the week and are looking for something else to add to your collection.
