Tantei wa Mou, Shinde Iru.

Kimihiko Kimizuka has found himself inadvertently entangled in various crimes more times than he can remember, referring to himself as a magnet for trouble. One day, as if it was nothing out of the ordinary, a group of unknown men kidnaps him, forcing him to board a flight—where he also encounters a hijacking. Amid the resulting chaos, however, Kimizuka meets a stunning silver-haired beauty, going by the codename Siesta, who then saves the day.
