It's Milfeulle's day off, and she plans to go hiking in the Transbaal area so she can see the flowering fields of the summit meadow. This also happens to be the one day when her misfortune takes over from her usual good luck. The more Milfeulle is plagued by misfortune, the more a galactic cataclysm is bound to happen.

In the end, Milfeulle goes to sleep happy about her day off.
