The raid ends with the heroes defeating and arresting hundreds of Humarise members, however no Trigger Bombs were found in the building. Because of that, the director of the WHA orders all the teams to remain alert in their respective countries. Several days later, Flect Turn, the leader of Humarise, publicly broadcasts to the entire world that in two hours they will detonate all the Trigger Bombs they have planted in the twenty-five cities where its branches used to be, including New York.

While a team of heroes raid the Jaku General Hospital, where the Nomu are created, another team does the same at Gunga Mountain Villa, the Front's main headquarters.

Rikido is a member of the Villa Backup Team along with some of his classmates and Class 1-B students. Their mission is to provide support to the heroes who raid the Gunga Mountain Villa and prevent villains from escaping.

After Tomura Shigaraki woke up and commanded Gigantomachia to go to him, Heroes try and fail to stop the walking calamity. Kyoka detects the giant and warns her teammates. Likewise, Midnight contacts the students and transmitting them what they have to do to stop the giant. Momo takes the leadership to defeat Gigantomachia and uses her Quirk to create a large number of vials of undiluted sedative, giving one to each student so that at least one can make the giant swallow a vial.

Following Momo's lead, the students set the trap for Gigantomachia. Juzo uses his Quirk to soften up the ground and Momo plant explosives she created in the softened area. They also position several chords covered in Minoru's orbs.

As they planned, Gigantomachia step into the students' trap and he falls to the ground. The strings covered in Minoru's orbs stick to his chin, and while the giant tries to get out, Rikido, along with Class 2-B members Itsuka Kendo and Jurota Shishida, pull with all their might on the ropes, intending to open his mouth wide enough to allow their teammates to throw the sedative inside him. Despite their efforts, Gigantomachia and the members of the League manage to repel the students.

Fortunately, Eijiro manages to throw a vial into Gigantomachia's mouth, and when the giant is about to crush him, Rikido and other students start shooting him with cannons created by Momo, allowing Eijiro to be rescued by Setsuna Tokage. Several heroes led by Majestic arrive to take charge of Gigantomachia now that he has ingested the sedative, because the more he moves the faster it will spread.

Gigantomachia takes on an armored appearance and easily defeats heroes, and continues on his way to Tomura. Before being killed, Majestic uses his Quirk to bring the U.A. students to safety, who can only watch helplessly as the giant devastates everything in his path. After the battle he, along his classmates, finds out that Midnight was killed and the students start grieving over their teacher's body.

Two days later, Minoru, Toru, Hanta, and Rikido see Katsuki wake up from his injuries, and are relieved that he is okay, taking his angry attitude as a sign of wellness. When Katsuki asks how everyone else is doing, they unenthusiastically explain that while most others are conscious, Izuku has shown no sign of waking up, prompting Katsuki to make his way toward Izuku's room. Rikido and Minoru try to stop him, though Katsuki brushes it off and says that their pulling him is killing him faster. Eventually, Katsuki is stopped by Tsuyu, who helps carry him away using her tongue. They notice Hawks and Best Jeanist going to Izuku's room, wanting to ask him about One For All.

Once Principal Nezu gives Class 1-A permission to bring back Izuku to U.A, Rikido joins with his class to search for Izuku while at the same time, apprehending any prison escapees along the way. After a month of trailing in Izuku's whereabouts, Class 1-A finally arrived on the scene to defeat the villain Dictator. When Izuku refuses to yield, he demands everyone to get out of his way, which means they'll have to fight.

As the fight goes on, Izuku tells them that his presence endangers everyone and fears of All For One killing them to break him, which is why he has to stay away from them. When he starts to break out of Mashirao's tail grip, Fumikage appears and uses Dark Shadow to knock him into a building. Rikido rescues Kyoka and Mashirao, reacting to Izuku's great strength, as he yells to him that while he may have a special power, they all share the same feelings, and to think about what they said, or else he won't let him use food coloring for Eri's candy apples, which Izuku attempts to brush off.

Once Izuku was caught up by Tenya, Rikido regroups with the rest of Class 1-A and listens to Katsuki apologizing to Izuku before he collapses from shock and exhaustion. He escorts Izuku safely with the rest of Class 1-A to return to a heavily fortified U.A. High where they are confronted by angry protesting civilians. They are aware that Tomura is after Izuku and fear them being in danger, leading Ochaco to give a pleading speech toward the crowd on why he needs their help and deserves to stay and rest, with the civilians eventually agreeing.

All Might informs all this to the class, telling them that this is now their perfect time to prepare for the inevitable all-out war. The class reveals over the past month they had been training with the Wild, Wild Pussycats in order to keep up with Izuku in the incoming conflict, and are now about to head out to continue their training.

Once the Aoyamas are restrained, he and the other class refuse to back down from the news despite Nezu's request, all in stunned and tears of Yuga's betrayal. He listens to Yuga's desperation that drove him to despair and then Izuku pleading to let Yuga help them, leading the class to realize Yuga may be the only one able to deceive All For One.

Shota then appears on a tablet screen, taking full responsibility and reveals that he has an idea. He listened to Shota's plan after the Aoyama Family's ears have been covered. Naomasa then has the Aoyama Family escorted back to their HQ, telling everyone not to say a word to anyone else about the plan while he and the rest of the class look on sullenly.

Back at Heights Alliance, Rikido takes a breather, before getting ready to gear back up, as he and everyone, with fire and rage in their eyes over the betrayal, prepares to bring All For One down once and for all. He joins up with their "Search Squad" to head out to hunt down the villains.

Later that night, he and his classmates return to Heights Alliance for a break, having come up with nothing in their search. All Might, Naomasa, and Nezu soon arrive to inform them all about their secret finalized plans for the upcoming Second War. They call in Hitoshi Shinso, revealing their plan to get him to brainwash the Aoyamas so that they can communicate with All For One without him detecting any ill intent.
