October 1, 2025F95

“SEXUAL FANTASIES AREN’T ALL BLACK AND WHITE — SOME ARE HIDDEN IN THE DEEPEST SHADES OF BLUE.”
STAINS OF BLUE is an erotic visual novel that explores the many aspects and shades of the Netorase fetish.
Guide your heroine through unique stories shaped by the personality you choose. Select from 5 different shades of blue each with their own unique personality and their own story to tell: from the tender and devoted hue of Aquamarine to the vivid and commanding color of Cobalt.
NETORASE is a spectrum, and what excites one player may not excite another. This game was made to embrace that diversity. Pick your ideal heroine’s personality, define the dynamic between you two, and let the game take you on a compelling journey into your own personal fantasy, crafted to let you explore what aspects of Netorase speaks to you the most.
Whether you are into CUCKOLDING filled with humiliation or raceplay, or the STAG & VIXEN relationship where both participates, simply making her a HOTWIFE and sending her off to her dates, or even treating her like an object you can just PIMP away to other men, shape the game according to what gets you going.
Mix and Match between personalities and your Netorase preference to craft that unique little story made just especially for you.

DEMO RELEASE DISCLAIMER: As this is only a DEMO, it only includes AQUAMARINE and COBALT. So if you are looking forward to play a different personality, please wait until the full public release.

Developer Notes:

Hey everyone. Some of you might remember me as the guy who made the NETORASE MASTERLIST, or as the one who was working on Tainted Aquamarine.

And now, I’m proud (and honestly a little nervous) to finally present to you: STAINS OF BLUE

This is the project that’s been in my head since the Tainted Aquamarine days.

In a way, you could say Tainted Aquamarine evolved into this. The themes and a lot of the ideas got carried over and expanded into something bigger, better, and more ambitious.

I have always envisioned to one day build the ultimate NETORASE game, and STAINS OF BLUE, is that vision, slowly coming into reality.

Please look forward to the upcoming official public release, and very huge thank you’s to those who believe in this very ambitious project.
