Nezumi no Hatsukoi

Here's the sweet, bloody yakuza love story we've all been waiting for! Nezumi was raised by the mob to be an emotionless killing machine, but a chance encounter in an arcade leads to a romance at total odds with everything she's known. Equal parts ultraviolence and kawaii, Nezumi's First Love turns both the hitman and love comedy genres on their heads!
