Takuto Hirukawa wakes up after having a dream of his ex-girlfriend. Later on as he and the rest of the Black Foxes are about to go on a mission, his ex Rina Tokuhara comes back and surprises them all but Hiro and Atsumu. Despite his mixed feelings towards her, he and Rina become partners once more. On the other hand, Hiro's friend Sayuri Mitsuyoshi turns out to be their enemy, but seems to be hiding more than what she tells the band of noble thieves.
