what's the usage of it?

[Flyin' High]

"Online play item. Restore the connection to other worlds.

Those who engage in unjust deeds when in contact with other worlds will lose their connection to them.

Way of White Circlets assume such sin as their own, but are found few and far between. Acting without honor will never be without risk. "

iirc it basically just unbans you if you get banned, you wait out your time or whatever and then you use the item to re-enable online play
I think this only works for bans associated with disconnecting during online play though, for cheating/modified files related bans I believe you have to beg bandai
