[Captain] Capitano, who was burdened with the curse of immortality, unexpectedly came to the world of Azure Files. When looking for a way to return to Teyvat, he met a "black server" who claimed to be from the "Secret Society of Numbers". The other party said that he could help [Captain] return to the original world. At the invitation of the other party, [Captain] doubtfully chose to cooperate with him.
