Keido Arc is the fourth major arc plot to be introduced on Devil Beater series.
Two weeks after the departure of Team Dimensionia, the Alliance recieves a letter from Ineur himself, giving a mission to annihilate a company called Keido Corporation, which took over Studdton after the economy crisis.
Two Weeks Later...Two weeks later, Gardi finds mail. Claude thinks that the mail is just weight programs for Egbert, with Egbert declining that he is on a diet. Alan lets out a undistinguished roar because of Egbert's use of egg puns. Vritra, Hop, and Sly try to read the letter, until an annoyed December interrupts the three and yells out why Egbert subscribed to the weight programs, while a confused Winchester questions about who said what. Jay said that none of that the interns say matter and lets Gardi read the letter. The letter was from Ineur, who wrote about a group of mafiosos who had taken control of Studdon. Reggie recalls to when he accidentally crashed the economy of Studdon and says that the pizza company KeidoCorps has taken over the food industry, meaning that the only food they can get is pizza. Gardi think it's neat and agrees to go to Studdon. Django wants to drive the bus, but Diablo disagrees and lets Zecon take the wheel.
Two hours later, the team arrive at Studdon. Vritra and December took notice of the mafiosos. Vis states that the team must fight them, however Diablo complains that there are too many people, but Jay tells them there is no time to complain and fight anyways.

Ace starts questioning Pezza about his hat if he would die when he took it off and he said it will be extremely painful. However, Diablo urges Pezza to fight but Pezza said that violence wasn't the answer and says he might be jealous of his hat or something. Ace says it looks stupid, causing the fight between the interns and Pezza to start.
After Pezza's defeat, he claims to go somewhere to have a super secret meeting with his "brother". Zecon interrogates Pezza where exactly, but Pezza tells him that's it and quickly leaves. Vis quicklys says that the crew must follow Zecon wherever he goes. Jay asks if he can have some control, but Vis replies with again, a simple "no".
