I want to but time doesn't permit me, sorry.About that trance thing,have you read the manga change123, the martial art girl number 0.its similliar to jyuubei, emotionless but sometimes ruthless but jyuubei i think was able to control the ruthless part of it.
About that "anouncement" thing to activate her powers, yes jyuubei have it but i can't remember, (lemme check the LN again) so no more kissing muneakira again and again
.The kissing part is just to initiate(1st kiss)and to finalize(2nd kiss) the contract with the general.
