Akane is despondent over the failure of her latest plan and stops sending kaiju to attack the city, leaving the Gridman Alliance to wonder what has happened.

Even though Yuta has lost his memories, he’s happy making new ones with his loving girlfriend Akane. Hey, wait a second…

Akane reveals to the Gridman Alliance that she’s been behind all the kaiju attacks, and warns them she’s going to destroy the upcoming school festival.

Yuta finally confronts Akane and her mysterious benefactor Alexis. Meanwhile, Anti continues to take matters into his own hands.

Yuta meets a mysterious child who claims to be a kaiju, who reveals the truth of the world to him. Menawhile, Akane has decided that murdering Gridman’s human partner would probably be a lot easier than killing Gridman himself, and sends Anti off to do the job.

The gang take a trip out to the country to go rafting. Akane decides that bigger is better, regarding both monsters and amount of fanservice.

Akane & Rikka go on a group date with some college boys, causing Yuta to get extremely creepy. Turns out Akane doesn’t like them that much, so she moves to the obvious next step – murder.

Akane creates a powerful new monster, which manages to defeat Gridman in battle. Sho and Rikka are forced to come to terms with the idea Yuta might be dead.

Yuta, Sho and Rikka discover that, although the school has been restored to good as new, the friends who were seemingly killed in the attack are still missing. They start looking into what’s happened but are soon confronted by the arrival of one of Gridman’s ‘friends’ and a fresh Kaiju attack.
