Fischl: Hello Musume! What’s going on?
Musume: Everyone’s having a breathholding competition. We’re trying to see who can hold their breath underwater the longest
Kashiko: Hey Musume, how come Sayori and Sephiroth aren’t in the competition? I thought they were so good at something like this
Fischl, whispering: Considering that Sayori and Sephiroth can breathe and speak underwater, they’d be overqualified so they are exempt from the competition in case it gets rigged in their favor
Musume: I guess that explains itself
