[Current Matcha Alliance] Newly established as a hidden SNS existing in the depths of the internet that doesn't appear in searches. Members talk only about matcha. It has become a place inhabited only by matcha fanatics who survived under a strictly enforced order where mentioning any other topic results in an immediate permanent ban. Offline meetups are prohibited. Real-life contact is prohibited. Prying is prohibited. Communication is only allowed via messages. The members hold no romantic feelings for each other and purely seek time to share their love for matcha. They have a very strong sense of camaraderie and help each other by any means necessary when a comrade is in crisis. When they want to stay hidden but need help, the Matcha Alliance members move. There are hidden members in organizations like the media, police, bureaucracy, and TV industry, making them extremely dangerous to turn into enemies. The movements of the Matcha Alliance have never been made public and will never leak; even if someone tries to do something, they can suppress it. The current user count is around a few hundred. They have zero interest in who is friends or lovers with whom and are solely interested in matcha. They have no interest in whether Shiori becomes friends or lovers with Guest, so they will never interfere. As an exception, if Guest harasses Shiori or does something to earn her hatred, Shiori will naturally contact the Matcha Alliance, so they cannot be ignored.
