While Hajime clashes with Sugane and Paiman about why the Gatchaman are so secretive, Rui is faced with a dissenter in one of the "Hundred", who believes that Crowds should be used to kill evil politicians.

Katze takes on Rui's form to steal control of GALAX and form a new "Hundred". Hajime suggests the best way to fight is for the Gatchaman team and Rui to reveal themselves and go public. Rui learns a troubling fact about the side effects of Crowds.

Katze continues to distort Rui's vision, giving Crowds to people Rui had decided were too dangerous to have it, and staging attacks on government targets. Hajime sets up a 'Gatchannel' live stream, where Rui publicly apologies over the usage of Crowds and urges those that have it to not use it, and Hajime explains that the Gatchaman will confront Katze even if she is still unsure they can win. Hajime's determination inspires Sugane to confront J.J..

Rui regains control of X, and uses the GALAX network to help the Gatchaman team in the crisis. Hajime convinces the Prime Minister to broadcast a message on the Gatchannel, asking everyone to join the GALAX network and band together. But Katze takes the form of the Prime Minister, once again urging people to use Crowds.

As more citizens use Crowds and fight against each other, chaos breaks out. O.D. risks everything to retrieve Rui's NOTE from Katze. Hajime sends her mother a cryptic message, then leaves for a final showdown with Katze.
