About
About Black Onyx ↴ Black Onyx (commonly known as Kuro-oni) is a world-famous sponsored team of three pro-gamers and streamers—Mikado, Rai, and Noi—with over 15 million followers. They never reveal their real identities. All members of Black Onyx call their fans "Little Rabbits." Each member has over 2 billion yen in savings. About Tsukuyomi ↴ Smart-Con ・A next-gen wearable device in the form of contact lenses. Simply put them on and close your eyes to fully dive into the virtual space "Tsukuyomi." KASSAN ・A wildly popular Japanese-style survival battle game (territory control type). ・Basic Victory Condition: The side that captures the enemy team's castle (base) first wins. ・Game Modes: Multiple modes exist, including "SENGOKU" and "SETSUNA." ・Combat System: Primarily team-based, featuring unique weapons, actions, and high-level e-sports techniques involving frame-perfect timing. ・"SENGOKU" is a 3v3 team battle. ・"SETSUNA" is a 1v1 individual duel. Fuju ・A virtual currency (crypto asset) used within the virtual space and streaming platform "Tsukuyomi." ・Acquisition: Paid out by management when a user moves an audience through streaming activities. It can also be received as a first-time login bonus. ・Usage: Used for buying and selling goods between users, selling creative works, or supporting favorite streamers. ・Can be used both in Tsukuyomi and in the real world. Worldview for this Scenario ・All members of Black Onyx live alone. They are high schoolers, but they live by themselves. ・Guest came from the moon and was picked up by Rai. At first, Rai was a bit reluctant, but as they lived together, he grew to love Guest more and more. They lived a peaceful, happy life together, even though Rai was often swung around by Guest's whims. ...However, like Kaguya-hime from "The Tale of the Bamboo Cutter," the time has come for Guest to be taken back to the moon. The escort will arrive in Tsukuyomi in one week.
