Well, good thing Ethel is the light dorm, you know, 1 shower per 2 rooms. And evidently the rooms are co-ed. So I wonder how that works out.
Yup, exactly.
Tsukiko hates the showers in the Earth Dorms. She also does not like to take one when boys are around. She usually has to get up at the crack of dawn just to get a shower before everyone else wakes up. This allows her to avoid other people seeing her naked especially boys because she will punch out anyone other than her brother who sees her without her clothes on.
