This is the first appearance of Jintsuu and I can take a guess where she falls on the chart

Jintsuu has a 'phobia' which is being afraid of people touching her skin. So it can explain why she suddenly jumped like that.

Goddamit Sakurako, this is the exact reason why there are so many raging lesbians in your base. You do stuff like this and then it bites you in the ass later.
Well, not that I mind. In fact, quite the opposite. Keep on truckin' Sakurako!

While hands_on_another's_hips isn't exactly right, I figure it's close enough.

Sazanami already said it - Sakurako turns Shipgirls bad. And turns them on.

I can understand Jintsuu's discomfort though... Maybe she might like it if someone discouraged Sakurako.
