About Koivis
Koivis is an ecchi visual novel that re-imagines classic anime scenarios, allowing players to date "all-star anime heroines" within a parody school setting. Tired of seeing beloved characters face rejection, Koivis puts the male protagonist in a position to change their fates. This dating sim experience focuses on romance, featuring 2dcg artwork and voiced interactions that bring the characters to life. The game is built around a sandbox structure, providing players with freedom to explore relationships and events over a five-day playtime period.
Currently available as Demo v0.0y, Koivis offers a substantial initial release with six fully implemented girls, each boasting over 10 CGs and a dedicated main event. The narrative also includes one central story event with multiple branching paths, ensuring varied outcomes based on player choices. The game embraces adult themes, incorporating elements of teasing, exhibitionism, and cfnm, all while featuring characters explicitly stated to be at least 18 years old within the game world. The developer has also integrated AI CG for certain assets, contributing to the visual presentation.
The core concept of Koivis revolves around the player's journey to re-experience youth and guide these heroines into adulthood through romantic interactions. While the initial prototype provides a solid foundation, the developer has plans for future updates, promising more characters, locations, events, and enhanced sprite movements to further enrich the gameplay experience. This commitment to ongoing development suggests a growing world for players to explore within this unique parody dating sim.

Story and Setting
The narrative of Koivis unfolds within a familiar school setting, serving as the backdrop for its parody dating sim elements. Players assume the role of a male protagonist with a singular objective: to date the "all-star anime heroines" who have historically faced rejection in their own stories. This premise allows for a lighthearted, ecchi-focused take on classic character archetypes, inviting players to forge new romantic connections.
The core storyline in the Demo v0.0y spans five days of playtime, during which the protagonist navigates school life and interacts with six fully implemented girls. Each heroine comes with her own main event and a collection of over 10 CGs, detailing various intimate moments and romantic developments. A central story event further shapes the narrative, presenting players with several paths that diverge based on their decisions, leading to different outcomes and character interactions. The game's overarching theme is a journey through youth into adulthood, experienced alongside these familiar, yet re-imagined, characters.
What Makes Koivis Worth Playing
Koivis offers a distinct experience for players who appreciate parody visual novels with adult themes and extensive dating sim mechanics. Its primary appeal lies in the opportunity to interact with "all-star anime heroines" in a new context, fulfilling the fantasy of dating characters often left unchosen in their original narratives. The game's commitment to providing numerous variations based on player choices, coupled with its "hp1 level" support for relationship building through activities like gift giving and joint studying, ensures a personalized playthrough.
The current Demo v0.0y already provides substantial content, including five days of playtime, six fully implemented girls, each with over 10 CGs, and a main story event with multiple paths. The inclusion of voiced content and detailed 2dcg artwork, including elements like big ass and big tits, caters to its target audience. Furthermore, the developer's transparency regarding future updates, promising more characters and events, suggests a growing and evolving game. The recent v0.2 update, which introduced GUI improvements, new character galleries for Yui and Mai, additional bonus CGs, and crucial bug fixes, demonstrates ongoing dedication to enhancing the Koivis experience.
