✦ AI summary

NinNinDays is a short visual novel centered around a cute ninja girl character with attractive artwork and pleasant music, but players find it suffers from a thin story that relies on standard anime tropes, limited player choices, and a high price point for its length. Common complaints include translation errors, minimal animation outside dialogue, and an overall sense that the experience prioritizes fan service and character appeal over meaningful narrative.

On one hand, I did enjoy this short VN with a cute ninja girl and it has a good gallery / memory feature, but on the other hand, it has several issues that prevent it from justifying a solid recommendation. [olist][*]Very short VN with limited choices - that makes the price point pretty high without a discount. [*]Story-wise, it follows the standard anime tropes of a rather cowardly protagonist meeting a clumsy dream girl. [*]R18 patch available on Qureate's page, but that one still has mosaic. You'll need to look a bit further for non-mosaic patch. [*]L2D animation is only for VN dialogue, the H-scenes are drawn well but are static images. [*]Some obvious spelling errors in English translation, though still comprehensible. [*]Game doesn't tell you when Sumire finishes speaking, so its possible to accidentally skip dialogue because there is a rather long pause between words. [/olist] Since Steam doesn't have a Neutral rating and the negatives stand out when compared to other VNs, I have to give it a thumbs down, even though I did enjoy it for the art and its specific appeal. Only recommend if you like Akasa Ai's art(yes, she's the artist for Hololive's Houshou Marine), ninja gir…

It's uninteresting from start to finish. Pointless story + only one character to talk. This was a complete waste of time for me. I've tried this because there are some games that I like from this developer. Art and music is nice but they are not going to save this.

NinNinDays, developed by qureate in collaboration with iMel Inc. and published by qureate and DLsite, is a lighthearted romantic visual novel that blends slice-of-life storytelling with a playful touch of fantasy. The game follows the story of a young man living a mundane life in Akihabara who suddenly encounters Sumire, a cheerful and slightly naïve ninja-in-training who ends up staying with him. What begins as an unusual meeting quickly turns into a cohabitation comedy filled with charming, romantic, and occasionally mischievous moments. True to qureate’s established style, NinNinDays leans heavily into fan service and character-driven humor, presenting itself more as an interactive anime episode than a traditional narrative-heavy visual novel. Visually, NinNinDays stands out among similar titles through its use of smooth Live2D animation that gives characters subtle motion and expression, adding a layer of realism to the standard static-sprite format. The artwork is vibrant and highly polished, showcasing professional character designs that align with the game’s light romantic tone. Sumire’s design in particular captures her personality perfectly—innocent yet energetic, with a …

5/10. Boring, even.

NinNinDays is a simple and short feel good visual novel about your everyday insert mc running into a country bumpkin ninja girl, and starting a life together. The story itself is fairly basic and simple, but that was obviously put on the back burner by focusing the attention on Sumire's character. She definitely feels like the average clueless waifu to be trope, but that is forgiven because Sumire is cute as a button. The real defining factor for NinNinDays is the fantastic art style which is just drop dead gorgeous to look at. The backgrounds, CGs, and character sprites are so fantastically done that it is just a pleasure to look at them. I totally recommend picking this one up for yourself at some point for the art alone.
