Once inside, they wait for Mikoto and Anna, greeting the former when they do. Soon after, Anna uses her abilities to read the gang leader's mind but is unable to retrieve any valued information from him; disappointed, Rikio and the others leave.

Approaching the hotel's lobby, they are confronted by SCEPTER4, and prepare to initiate in battle against them, using their group's infamous war cry as a motivator. However, the results of the battle leave Mikoto arrested and jailed, while the others continue pursuing their main target. It is not long after that they find a male teenager closely identical in appearance to their target; believing them to be the same person, Homura strikes again. Rikio joins the new pursuit and eventually corners the teenager in an alley with Izumo; however, he is rescued by the unexpected Kuroh Yatogami.
