Subaru arrived in Marina will all of her powers and weapons, because the majority of that is handled by her A.I. partner, Mach Caliber. MC is lives inside a tiny jewel that Subaru wears around her neck, and she was not confiscated because she is a trinket.
Will she be confiscated as a "weapon" or inside the paper bag with other items she had on her person at the time the transfer was made, just s per her arrival in Marina? I know she will not be able to access / use any of this because of the bracelet, of course.
