While taking a stroll at night, Michiru notices someone seemingly in trouble, so she decides to help them. Turns out she unintentionally helped out an infamous criminal named Kawakami Bansai. From there on, while both manage to see and text each other, it ends up getting complicated when Michiru realizes she can't tell anyone about this, both him as Kawakami Bansai and as Otsu-chan's music producer, Tsunpo. She especially can't confide this to her twin sister.
