Mystery with my Friend, A Comforting LGBTQ-themed Mystery Novel Now Available for iOS and Android



Mystery with my Friend, a visual novel game originally launched in Japan and the #1 title of its genre in the Japan app store, is now available for iOS and Android. The game comes at a time where diversity and inclusivity are increasingly becoming more important, especially in games where LGBTQ characters and themes are often limited. The visual novel is intended for contemporary people in a dramatically changing world and places an emphasis on diversity and inclusivity as various LGBTQ characters and their stories are depicted in-game.

As the main character of the visual novel app, you can read a story about a gay detective who works as a tailor and how he solves the little mysteries of everyday life. There are also characters with various gender identities in the stories, including the tailor detective’s ex-boyfriend, a lesbian girl, and a non-binary individual.


1. App features

A stress-free experience

To enable readers to enjoy the story without any stress, we aimed to create a simple design by removing gachas, health, and as many elements that require time and effort as we could. All main stories are available for free, without any limit on re-reading them. An auto-bookmark function allows readers to read whenever they have time by automatically saving the place where they last left off.
