On his first day of school, Ichika already has a group of admirers, has to room with his childhood friend (who’s not happy), and a lot more problems he didn't foresee.

A one on one battle with Cecilia Alcott looms over Ichika, and he becomes worried. Houki trains him, and Ichika becomes the proud owner of a custom IS.

A double dose of trouble is just the beginning, as Ichika also struggles to learn the ins and outs of piloting his IS.

Ichika vs. Rin! Right when the match starts to heat up, a mysterious IS decides to crash the party. With an unknown pilot, they try to stop it.

It looks like Ichika's got new competition. A new male student arrives, a representative from France who is dashing, polite, chivalrous and....well, another boy!

A new contender enters the ring, as the representative from Germany, Laura Bodewig, makes waves as the new transfer student, immediately calling out Ichika and giving him a good smack to the face.

The third Generation IS makes its debut as Laura gets set to battle both Lin and Cecilia at once! Is this 2 on 1 battle too much to handle?

The tournament has begun, and a battle royale between team Ichika/Dunoa and Team Houki/Laura is the main event! How will Ichika fare against his unlikely opponents?

After the events that unfolded in the tag team match, Ichika & Co. deserve a much-needed beach trip. Schemes, traps, and frilly swimsuits abound.

Houki's eccentric older sister, and the creator of the Infinite Stratos battle suit, finally makes an appearance and brings with her a new toy.

After the last battle with the Gospel, Houki becomes disillusioned with IS. Ichika remains in critical condition, so it is up to the girls to stop the Gospel on their own.

The final battle is at hand! The Gospel IS seems like an unstoppable force, and it will take all the teamwork, trust, and power that the girls can muster to take it down.
