Developer Notes:

Prologue:

In My Girlfriend Mizuki Hiro is consumed by an intense, all-encompassing love for his girlfriend, Mizuki. His obsession began in the third grade and has only grown stronger with time. At Hope University, he finds himself constantly aroused, his mind and body driven by an insatiable desire for her. His nights are filled with erotic dreams, his body trembling with unfulfilled longing.

Hiro’s thoughts are a whirlwind of fantasies, often imagining other men pursuing Mizuki, their hands roaming her body, their eyes filled with lust. These visions ignite a wildfire within him, a mix of jealousy and passion that drives him to the edge. The game’s prologue explores Hiro’s internal struggle, his vulnerable confession, the playful flirtations that define their relationship, and the intense, life-changing moment when they finally make love. My Girlfriend Mizuki is a story of deep emotion, unbridled desire, and the profound connection that binds them together.

Gameflow:

As the main game unfolds, you’ll navigate Hiro’s life through a series of daily decisions, each one shaping his journey and his relationship with Mizuki. The day is divided into distinct segments—morning, afternoon, and evening—each offering a variety of potential actions to choose from. Your first option in each segment is to Skip, allowing you to fast-forward through the day, but this choice comes with the risk of missing out on crucial events and opportunities.

The other choices are where the game’s depth lies. Selecting these options triggers events that can significantly impact Hiro’s life and his connection with Mizuki. Successfully completing these events rewards you with increases in key stats such as Affection Points, which strengthen your bond with Mizuki, or NTR Points, which advance the rival subplot. These stats are crucial for unlocking new scenes and progressing through the story.

Each scene in the game has specific conditions that must be met to activate, such as accumulating enough NTR or Affection Points, or making particular decisions at critical moments. This creates a complex web of choices and consequences, where your decisions directly influence the story’s direction and Hiro’s emotional journey.

How Netorase and Netorare works:

For the Netorase path, you must take a bold step by confessing to Mizuki at night, revealing your desire for her to cuck you. If she accepts, you become her cuck, unlocking all Netorase events for each segment of the day. This transformation allows you to explore a range of scenarios where Hiro is submissive.

For the Netorare path, the game provides a unique route during school hours. This involves a bully storyline where Netorare is available, offering a different dynamic where Hiro’s jealousy and humiliation are explored. Unlike the Netorase path, the Netorare route is available immediately, allowing you to dive into these scenarios right from the start. This path focuses on the rivalry and the emotional turmoil that Hiro experiences as he watches Mizuki interact with other men.

Additionally, the game introduces the Red Rabbit Streamer path, where Hiro’s jealousy and humiliation take on a new dimension. In this path, Hiro discovers that Mizuki has been interacting with other men through a popular streaming platform, further intensifying his emotional turmoil. The situation escalates when Mizuki becomes involved in a significant issue with a particular man, adding a layer of drama and tension to the story. This route adds another layer of complexity to the Netorare experience, as Hiro grapples with the reality of Mizuki’s online presence, the attention she receives from other men, and the emotional impact of her encounter with this particular man.

How Endings work:

The general ending is activated by pushing the “See Ending” button.Depending on what routes you fully complete, the ending will change. For bulls, they will join if their routes are completed; otherwise, they won’t show up. You get a better sex scene with Mizuki if you finish the night exhibitionism route. Completing the humiliation route will also add more to the ending. However, forthe red rabbit route, the endings are integrated into the route instead of being the See Ending button.

Characters:

Mizuki

She is a young girl from Hope University who the main character has always had a crush on. Despite her youth, she possesses a complex personality that is both intriguing and perplexing. She is often seen as cringe by those who don’t understand her, but those who do see her as incredibly smart and insightful. Her otaku tendencies are evident in her vast knowledge of anime and manga, which she often references in her daily life. Her extreme perversion adds another layer to her character, making her both alluring and controversial. Additionally, she is from WaifuTube and a streamer, where she showcases her unique personality to a broader audience.

Hiro

The main character is driven by an initial desire to pursue a romantic relationship with Mizuki, evident from the start of the game. He is also an otaku, deeply immersed in the world of anime and manga. His infatuation with Mizuki dates back to their third-grade days, a crush that has endured over the years. Despite his extreme perversion, his physical attributes, particularly his cock size, do not align with the intensity of his desires.

Mr Kanzaki

Ms Shizuka

However, years of divorce and loneliness have instilled in her a playful, sometimes overly flirty disposition, giving her a surprisingly bold edge beneath her sweet exterior.

Kazuma

The narrative explores Hiro’s darkest urge, where he considers manipulating Mizuki into receiving these private sessions.

Hasogawa

This is the game’s bully, a character who uses aggression and intimidation to get what he wants. His aim is to force Hiro to manipulate Mizuki into spending time with him and eventually dating him. If Hiro resists, the bully will resort to physical violence and humiliation. You might encounter him by wandering the university grounds during the lunch period.

Mizuki’s Bull from dating app
