Bang, Bomb, and Fubuki, all of whom were previously excluded from the operation, joins the S-Class heroes on the surface. Most of the heroes on the surface was unaware of this and Atomic Samurai proceeds to question Child Emperor. After everything is explained, Bang forgives Child Emperor while Fubuki pleads to the heroes to assist her sister Tatsumaki as she was losing consciousness.
While Drive Knight and Genos protect an unconscious Tatsumaki from Psykos, she has a flashback to 18 years ago in some research institute. A monster goes rogue inside the institute and Tatsumaki was locked in her cell, unable to escape. Blast saves Tatsumaki, quickly recognizing her power and convinces the young girl to use her powers to protect her family. Tatsumaki regains consciousness and the battle proceeds.
Drive Knight chases Psykos into a tunnel while exchanging a series of attacks. Tatsumaki joins in and creates multiple obstacles within the tunnel to trap Psykos, albeit unsuccessfully. As Psykos exits the tunnel, she is caught by surprise when Genos runs by and jumps on to her jet, thus allowing Drive Knight to do the same. The two heroes then prepare to finish her off.
