The Detective Is Already Dead, Vol. 2 (manga)

She wants him to find out who she's looking for...What an appropriate request for a girl who believes nothing is less reliable than subjective opinions. Ex-ace detective's assistant Kimihiko Kimizuka's initial lead on Nagisa Natsunagi's odd demand leads him to an old acquaintance-a convict named Bat with extraordinary hearing. As they reminisce about their initial encounter of when Bat hijacked a plane because he was desperately bored, Nagisa wonders if there's more to the story...
