Do আপনি know this anime?

i hava a প্রশ্ন i ever had seen a part of an জীবন্ত but i dont know what জীবন্ত that is, maybe আপনি know: It begins with a girl sitting in a taxi looking out the window than the taxi stops and the taxi driver opens the car trunk. When he wants to take out the suitcase of the girl it opens and there are বন্দুক and boms অথবা something inside it.... ^^
