Similarities: Female fighters, ecchi elements, decent art.
KBW's MC is female, tho. It's also slightly more focused on fighting than the ecchi and romance.
On the plus side, it'ss a full series with 19 volumes, so if you're disappointed with the premature end of "B Reaction" and want to read more of something similar, check this one out.
