Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
According to the information I have learned, the app may adopt a distributed architecture. The location of server 1 and server 7 may be between different data centers or cloud service suppliers. If these servers suddenly disappeared, there could be the following possible reasons:
1. System failure: Due to the distributed architecture of the app, its servers may be distributed between different data centers or cloud service suppliers. If one of the servers fails, the entire system may not function properly.
Physical Failure: The physical location of the server may change, for example, the server may be moved or replaced. If the server is moved or replaced somewhere, it may no longer be available.
3. Attacks: The server may be hacked to cause it to be deleted or disabled.
If the server of the app is missing, it is recommended to immediately contact the technical support team to understand the specific location and status of the server in order to take appropriate measures to solve the problem in time.
There were some differences between the international server and the Asian server. Compared to the international server, the Asian server had a lower delay and a faster queuing speed. However, there was no discount on the top-up price of the Asian server, unless it was a zero-charge player. The international server was more conscientious in terms of top-ups. One could obtain Obsidian, props, and fashion items through watching advertisements. In addition, the international server performed better in terms of optimization. Compared to the Asian server, there were fewer frame drops. In summary, choosing an international server or an Asian server depended on personal preferences and needs.
