Despite the judgement's scoring, Sakuyo comments on Rentaro's working to be incompetent as she found an odd on his style, even goes far by telling that Rentaro doesn't fit to accept his Tachibana title which angering him. But after Rentaro slaps her until she falls to the ground, Ark hacks her and turns her into a Magia.
Aruto tries to stop her by accessing into Zero One Flying Falcon. But Gai interfere by transforming into Kamen Rider Thouser and going to beat him up alongside destroying Sakuyo for getting in his way.
