Soul Unison!

English version title - DoubleSoul! Flashman, a Darkloid member, is hacking into light-related devices all over the city, causing a lot of mess. Once he hacks into Netto's school, he sneaks out to investigate the situation. However, Meiru follows along as well, offering a hand... which ends up causing Netto to lose to Flashman and damaging Rockman badly. While Yuuichirou is repairing Rockman at the labs, Flashman attacks again... but in order to prove her worth, Meiru goes off to stop him herself!
