Hoshiko: So from what I learned from Midori the other day, apparently Ayano can tie a weight to Osana’s pigtails and drop the weight into the swimming pool, causing Osana to sink considering how long Osana’s hair is in reality. If tying a weight to Osana’s hair and dropping the weight into the pool, therefore drowning her, could work, maybe I can drown Sephiroth in the same manner. I mean, his hair is just as long as Osana’s if not longer
Musume: That same trick which worked on Osana will likely fail on Sephiroth. One, he is more vigilant about his surroundings than Osana is. And two, even if he was unaware enough of his surroundings to hypothetically let it happen, he can breathe normally underwater, which would allot him more than enough time to figure out what is going on, untie his hair from the weight, and then resurface safely
Hoshiko: Oh, man! If that’s the case then I’ll have to think of something else
