Ayase single-handedly carries this game. Yuzusoft wrote her into a middling route with a divisive mc amidst a poorly paced plot, and yet she made this game into a comfort title that I still come back to.

"Riddle Joker" is a solid visual novel that focuses more on character interactions and romance than on its overall plot. We play as Satoru, a secret agent who enrolls in an academy while hiding his identity. The premise involves supernatural abilities but keeping things relatively light and focusing on daily life and relationships. The main strenght of the game is its cast. Each character has a clear personality, and their routes are enjoyable mainly because of the interactions, humor, and character development. Even if the main story isn't particularly deep, the characters make the experience engaging. The pacing is consistent with lots of Slice Of Life moments. In terms of presentation, it delivers what you'd expect from Yuzusoft. High quality artwork, expressive characters, good voice acting, and a solid soundtrack that fits the tone of the game. Overall, "Riddle Joker" it's an enjoyable visual novel with a strong focus on its characters, and it's easy to recommend if you like lighthearted romance-focused stories. As a final note, the game also includes optional adult content (+18), but it's not part of the default version that we can buy here in Steam. If you want to access to it, you need to download and install an additional +18 patch from the official Yuzusoft website.

This is currently my second favorite Yuzusoft game, after Sabbat of the Witch. That entry has higher highs but I actually think Riddle Joker was more consistently enjoyable throughout. The plot is not very ambitious but I think that actually works out to be an advantage. Yuzusoft's works can run into issues where the plot is initially presented in a way that leads to disappointment in later parts because of the lack of exploration into certain things it seems like they were setting up. In Riddle Joker's case, I never really felt that disappointed in the direction routes went and how they intertwine with the original plot, and when the plot did become more of a focus, it was continuously engaging on some level. The smooth combination of a relatively orthodox superpower/spy story provides an opportunity for an interesting hook and setting, and I never found the drama that occurs because of the MC's position to be grating. Some routes definitely go in a way where all the plot that occurs before is basically just garnish, but even when it goes into that territory, it is still very successful in its moege goal of creating very cute moments. An example of this would be Hazuki's route, which I was surprised at how much I enjoyed despite being like 90% fluff. Additionally, imouto routes will always get some bonus points from me of course.

Riddle Joker is a visual novel made by Yuzusoft. While they're more well-known for works like Sabbat of the Witch and Senren Banka, I ended up liking Riddle Joker a lot more. The moment I picked up this VN, I was basically glued to the screen, and ended up finishing 40+ hours of reading in under two weeks. Given Yuzusoft's reputation, I was expecting a laid-back slice-of-life story, and boy was I in for a surprise, because it was way more intense than I expected. The story is much more important this time around, the overall tone is more serious, and there's a lot more tense situations. I would go so far as to say this is more of a sci-fi and mystery story, with the romance and cute girls being tacked on. Yuzusoft works all have the formula of blending supernatural elements into an otherwise mundane setting, and IMO this is the best implementation of a supernatural element. The supernatural mechanic is explained clearly and in detail, making it easy to understand and follow along. This made me much more invested, to the point where I often stopped and wondered I would do in that situation. (This is in stark contrast to many other magic systems I've seen, which are so vague that the writers can basically do whatever they want, which causes me to lose interest.) The cast is one of the best I've seen. The protagonist isn't generic- he has a clear identity, purpose, and strengths and flaws. The heroines, likewise, mostly have unique personalities and don't fit into the standard archetypes. I ended up coming out of the common route liking every heroine, and couldn't wait to read all of their routes. Speaking of routes, it's best if you read them in a specific order: Hazuki -> Chisaki -> Nanami -> Mayu -> Ayase. You can shuffle around the first three if you want, but it's widely agreed that Ayase's route should be done last, and Mayu's second last. This order is crucial if you want the optimal experience of gradually putting together the pieces of a puzzle. The combination of interesting characters, an engaging sci-fi element, and the well-paced experience of unraveling the mystery, is what kept me invested and constantly wanting to read more. Aside from the story, everything else is great too. The visuals look amazing. The soundtrack is decent. There's plenty of quality-of-life features, like voice timer, flowchart, and dual-language support. (Though all of this is to be expected from Yuzusoft.) Riddle Joker ended up being one of the most interesting experiences I've had. I came in expecting a comfy slice-of-life story, got something rather different, and ended up enjoying it anyways. If you're looking for a relaxing story full of cute girls, you might want to look elsewhere. But if you don't mind something a bit more intense, I highly recommend giving this a try.

Though not as well - known as other Yuzusoft titles, this game doesn't fall short in production quality. It features a consistent art style and a substantial plot with twists. The story can't be fully uncovered without a perfect playthrough.
