Background / History

The Myriad Worlds Chat Group invited Izayoi Sakamaki while he was waiting for his Hakoniwa invitation. It connected him with individuals from other worlds through a mental interface and announced his arrival as an “Unknown Entity.” 1

Its early economy was based on Points gained through sign-ins; ordinary sign-ins generally yielded 1–5 Points, though larger rewards were possible. Members considered Points highly versatile and used them for items, abilities, and other services. 1

The Group’s Task System first activated when Tony Stark requested help after being kidnapped. Izayoi accepted the rescue mission and was immediately transported to Tony’s location. After completing it, he received 10,000 Points and became the Group’s sole Level 1 Administrator. 4 5

As activity increased, the Group automatically added members such as Kurogane Ikki, Minamiya Natsuki, Brunhilde, and Gilgamesh. At Izayoi’s request, it also gained the ability to send prepared explanatory information directly into the minds of new members. 6 21

Upon reaching twenty members, the Group unlocked a sales function, allowing members to earn Points by selling goods or resources. 105
