The day of admission to Hayato's Little Garden. Noah and Yukiume, who came to pick up Hayato at the airport, were late for the entrance ceremony and were dropped out by the student council president Claire. It was roommate Emile who rebelled against it. Emile is also expelled from school. Claire challenges Duel to settle with the dissenting Hayato. If Hayato wins, the three dropouts will be cancelled. Hayato plans a strategy with Emile and faces a duel with Claire.

Hayato will experience the first actual battle against Savage in the Zwei Islands. Overwhelmed by the fighting power of Claire, Liddy, and Erica's student organization members, she fights well with Emile. However, the war situation deteriorated in front of the giant species, Trenta-class Savage. Emile tries to protect the downed Liddy, but Savage tears her variable suit apart. There is a bulge in the chest and an old wound under the suit.

Meanwhile, Emile and Hayato are trying to stop more replicants from making it into the city. Sakura and Karen watch from below, but ultimately they come up with a plan...
