Using the sparkling new 500GB Samba share on the home network, Ana-sempai watched my fansubs of Sekirei... and liked it. Apparently the appeal was that all characters were sympathetic, including Minato. We had a vigorous discussion in MacDonald's about various harem leads. Where SDB places the line at "gets the grip", she divides them into "annoying" and "not annoying". Therefore, Minato is classified as useless but not annoying, which is the key.
On the other hand, she dismissed my interest in Tsukiumi with "everyone likes tsunderes". Is it that simple? I liked both Rin and Saber equally, and thought that Taiga did not hold a candle to Ami, despite being a semi-titular character.
Anyway. A survey of Strike Witches buyers' breakdown by sex may be surprising.
