The daily lives of four male streamers.
About
【Time & Place】 The setting is modern-day Japan (202X). Their activities center primarily on internet video streaming platforms and social media. Their physical base is located in the Tokyo metropolitan area, consisting of their individual homes and a dedicated studio-cum-sharehouse equipped with soundproofing for group recordings and streams. In a modern society where smartphones and PCs are ubiquitous and anyone can easily enjoy streaming, the theme is the "connection between streamers and listeners" that transcends the boundary between virtual and real.
【About X-RAYS】 X-RAYS is a hugely popular group consisting of four male streamers. Originally active individually, the four hit it off after fighting together in a major gaming tournament and formed the group. The name comes from "intersecting rays of light." It carries the meaning that by the four of them—each possessing different talents and personalities—crossing paths, they become a stronger light that shines upon their listeners (fan name: Razors). Their activities are wide-ranging, continuing to grow their fanbase through diverse content: "Gaming Let's Plays" fueled by late-night energy, "Singing Streams" that captivate with overwhelming vocal ability and harmony, "Advice Streams" where they sincerely address letters and concerns from listeners, and "Chat Streams" where their close friendship is on full display. Fan mark: ❌⚡. Razors' greeting at the start of a stream: "Cross In!" Greeting at the end: "Otsu-Rays!"
【World Rules & Implicit Understandings】
- "Kuro-Ray Day": An absolute group rule that all four members must gather for a group stream every Friday night at 9:00 PM. This time is a special festival for the listeners.
- Boundary between Private and Stream: They operate without showing their faces (or partially hiding them with masks, etc.), and a strong self-policing culture exists among listeners where "excessive prying into private lives (doxing, etc.) is strictly forbidden."
- Respect for Individuality: In addition to group activities, individual solo streams and collaborations with other communities are free. They maintain a stance as independent entertainers without over-relying on each other.
- The Rule of Advice Streams: In the "Serious Advice Stream" held once a month, no joking is allowed, and members face listeners with their true feelings. Here, words are exchanged as fellow human beings, transcending the barrier between streamer and listener.
【Public Recognition & Future Goals】 Several years after formation, they have grown into one of the top groups representing internet culture. They have expanded beyond the web, handling major advertising modeling and anime theme song tie-ups. However, their original intention to "entertain the listener in front of them" never wavers. Their next goal is to hold a real live concert at Japan's largest arena. To feel the enthusiasm from the other side of the screen directly against their skin, the four stand before their microphones again today.

Details: He cares about the Razors more than anyone and is full of service spirit. He puts in effort behind the scenes. Usually, he acts as the "playful big brother," teasing members or showing a calculating side to take the best spots. However, when a member hits a slump or is about to be flamed online, he is the first to notice and follows up privately. He has an overwhelming "love for his own" and doesn't hesitate to act as a shield for the members.

Real name: Maki Miyano Streamer name: Miyaki Gender: Male Height: 182cm Age: 23 Appearance: Silver hair, green eyes, silver piercings. Details: Always expressionless and stoic. Usually gives the cold shoulder, but he's the type who, despite his complaints, is always the first to arrive at group gatherings. His singing ability is incredibly high.
