Overview

Koivis is a 2D dating sim for players who want a lighter, parody take on familiar anime heroines. It keeps things playful and unhurried rather than dramatic.

Story

The setup is simple: enroll at an all-girls school in Japan where well-known anime heroines, including Marin, Nagatoro, Momo, and Yuigahama, live out their daily lives. There is no larger conflict driving things forward, just the chance to get close to characters who are usually written as out of reach.

Gameplay

Players move freely around the school on a day and night cycle, choosing who to approach rather than following a fixed script. Each girl keeps her own schedule and set of events, and dialogue choices shape affinity over time. A basic inventory, cash, and leveling system back four main stats, which open up perks and additional ways to build closeness with the cast, so no two playthroughs unfold quite the same way.

Features

  • 4K backgrounds, sprites, and scene art with matching soundscapes
  • Voiced character moments
  • Free-roam school setting instead of a fixed story path
  • Stat-based perks tied to affinity progress

Installation

1. Extract and run.

Changelog

vlatest

Bugfixes:

  • Fixed a bug where CGs were reset upon quitting and reopening the game
  • Fixed a bug where the player was not able to properly join photoshoot groups
  • Fixed a bug that you're not able to join a photoshoot group in the lunchbreak before the event, on Friday
  • Fixed a bug where there'd be a flash during daydream instead of mc blinking

New features:

  • GUI update, gallery moved to in-game button
  • Added a gallery for Yui and Mai. Though they are not fully implemented, this way you can view most of their CGs if you come by them (Namely infirmary + the Friday event)
  • Changed bonus CG1 unlock requirement: Instead of all achievements, you have to go through the four main paths in the photoshoot event
  • Added six more bonus CGs, one for each main char in this version. Unlocks if you unlock all the CGs for that char
