Actually, the laundry was clean.
Spotted hanging out to dry in a small village in Shizuoka Prefecture.
Note the Tenshi no Revolver bath towel (left) and Warp Days bath towel (right.) Underwear choices suggest that this is the abode of a fanboy, not a fangirl.
P.S. It was raining that day. Who hangs out their tour towels to dry in the rain? Fanboy, you can't fool us. We know you left that towel out specifically for us to find.
