It’s a rainy day in Tokyo when the newest kaiju appears, and this one seems different, because Akane isn’t making a model, but interacting with a small silver-haired boy named Anti who can transform into a kaiju. Why does he eat like he does, and why does hate Gridman so much? We don’t know. For that matter, we don’t know why Akane hates Gridman and wants him dead so badly, aside from having lost to him twice.
In any case, the Gridman Alliance is collected by Calibur, and before Rikka can apologize for not answering Yuuta’s phone call, Yuuta heads into action—and once again has his ass handed to him. Combined with Yuuta’s worry that he may be fighting/killing a human inside his opponent, he doesn’t fight back, even with Calibur by his side, and the two LOSE to Anti, much to Akane’s elation.
Rikka and Shou are stunned. They fear Yuuta and Calibur are dead, and in lieu of knowing what to do next, they wait in the shop and snipe at each other out of frustration. Their quarrel is broken up by the arrival of the “Neo Genesis Junior High Students” a team allied with Calibur and Gridman (and whose name is an homage to Evangelion). They tell Rikka simply to call Yuuta, and to her and Shou’s great relief, he is alive, and Gridman is simply regenerating. Before long he’s back in the fight.
One of the members of Neon Genesis joins the battle in the form of a battle tank, and combines with Gridman to form a new set of extra-chunky arms and fists with which to defeat Anti, who “runs out of time” in kaiju mode and reverts to human form, after which he’s basically disowned by a furious Akane.
Back at Junk, Rikka apologizes to Yuuta, which is something I think is way overblown in the grand scheme of things (I mean, people miss calls; she was trying to help someone she thought was in need), while her mom (who is voiced by the same actor who portrayed Haruka in FLCL) wonders where so many new people suddenly showed up in her shop.
While Gridman’s defeat was a nice change of pace, the fact it was resolved so easily—with Rikka and Shou simply sitting around until the cavalry arrived—kind of gutted the suspense. Everything is in a very bad way, and then moments later everything’s fine and dandy.
As for why Akane is doing what she’s doing, where exactly Anti came from, and other mysteries, lets just say I’m not holding my breath for satisfying explanations. Perhaps it would be best to just sit back and enjoy the action…it would just be nice if it meant more.
