How he can stay as faithful as he is to Sazanami sure is something.

I guess it makes sense she'd rather cover the admiral with a towel than herself.

If she knew about her counterpart in the R-18 parallel universe she would be even more upset that she is stuck with this completely Sazanami-sexual admiral here in the all-ages 'verse.
