Why the sudden surprise & outrage in the comments? Remember the very first strip when Kashima & robber bro met?
Kashima was already broken.
I think most people (including me) thought she acted that way because of all the lewd art that was drawn of her. This strip here changes all that in a very, very bad way.
From the first strip isn't Kashima's current admiral the shota? This scumbag might be just some other admiral who sees shipgirls as mere playthings.
Note the composition of the strip, along with the darkening of the background page normally used I flashbacks. This particular event pretty much happened in Kashima's past. Likely she was reassigned to the current shota admiral later.
