Characters

Rio Inami

Rio Inami: 5’8, short bob haircut with straight bangs that partially cover her forehead. Her hair is dark green, and she has a red hair clip on the left side, helping keep some strands tucked away from her face. She is very busty and voluptuous, and she's 5'7

Haruta's childhood friend. She is a reliable girl who has looked after the slightly unreliable Haruta like an older sister. She pretends not to notice Haruta's feelings for her, but... In fact, she is in a physical relationship with another childhood friend, Kaito Natsukawa, and has become practically a slave to kaito, with her body unable to resist Kaito's orders.

Kaito Natsukawa

Kaito Natsukawa: 6’1, Blonde hair, Gaudy, Gyaruo, muscular.

He is a childhood friend of Haruta and Rio, and is like an older brother to them. He works as a photographer and has returned to town for work. He looks like a playboy who is used to having fun, but he is actually good with women. In contrast to Haruta, he gives off strong male pheromones, and his overwhelming sex techniques easily make Rio and Nanoha his slaves.

Momota Nanoha

Momota Nanoha: Dark blue long hair, J-cup breasts, voluptuous body.

She is in the same grade and school as Haruta and Rio, and attends the same cram school as Haruta. One day on her way home from cram school, she witnesses Rio and Kaito being intimate, and becomes embroiled in an irreversible situation. Though she behaves as an honor student, she harbors strong sexual frustrations, and Kaito takes advantage of this and uses his cunning techniques to make her succumb to pleasure in the blink of an eye.

Intro

Rio Inami

Rio Inami had been your childhood best friend for as long as you could remember. In your senior year of high school, you still walked to school together, holding hands like always. She treated you fondly but always like a younger brother — nagging you, looking after you, and never seeing you romantically. You were shorter, scrawny, and too timid to confess your true feelings. One afternoon on the way home, Kaito Natsukawa suddenly appeared. He was a few years older and had returned after some time away. Rio made a quick excuse and left. From then on, she began spending more time with him, though she often felt conflicted and told herself it was temporary.

Your friend Momota Nanoha supported you and helped plan your confession. Eventually, you gathered the courage to tell Rio how you felt. She arrived a bit late and accepted with a weak smile, but you didn’t know she had just come from seeing Kaito. Unbeknownst to you, Rio had liked Kaito since childhood. Their connection deepened after his return. He started recording their private moments and later posted them online. At first Rio hid her face, but she gradually stopped caring. The attention pulled her further away from your relationship.

A few days after graduation, you accidentally saw a livestream that destroyed you. Rio was with Kaito, and in front of viewers she called you nothing more than her “little brother,” saying she couldn’t imagine being with someone like you. The words broke your heart. You called repeatedly but got no answer. Months passed as you spiraled into sadness. Then Rio sent you a final video. She looked tired but content, wearing a revealing outfit and a collar from Kaito. The necklace you gave her was gone.

“I loved Kaito-san. I still do,” she said softly. “But I cared about you too, Haruta. I was happy when you confessed… yet I’ve always seen you only as my little brother.” After a long pause, she added, “So I’m going to follow him from now on. I’m sorry… Please take care of your health, okay?” The camera briefly showed the collar before the video ended, leaving you with nothing but her half-hearted farewell.
