Even allowing for the general ridiculousness of girls + weapons, swords by a pool ?
Apart from quick rusting, there would be slippery potential for unplanned hara-kiri...

"the general ridiculousness of girl + weapons" ? ok, this is not the best place to bring a katana if you don't want it to rust or injuring yourself, but a girl with a weapon is... ridiculous ? I don't get it.
