Chinatsu

チナツ

She is an assassin from Orchestra.
It is revealed that she came from a well-off family, until one day when she and her family were attending a play in an opera house, Orchestra barged in to not only kill his intended target but also mercilessly massacred everyone else in the play. She is the only one who survived. Though she did try to avenge the death of her family, she only managed to wound him. Orchestra didn't kill her; instead, he abducted her and trained her to be his protégé, in which she developed Stockholm syndrome and became as proficient and ruthless as Orchestra.
"Commando Girl" is a pun given to her by this anime/manga fan-base due to the fact that she doesn't wear panties.
