Scar-red Rider XechS

To defend against Nightfly O'Notes, invaders from another world, mankind has organized the five-man fighting team "Scar-red Rider XechS." However, one of the Riders, Yosuke, is saddled with a serious problem.

When Akira, the new instructor-in-charge, assumes her post, the Scar-red Riders' leader, Takt, finds himself unable to trust her. Friction arises between Takt and Yosuke. During all the discord, there is an enemy attack.

After being hurt in battle, Hiro's physical injuries heal, but as he grows more distant from the group, it becomes obvious that some mental wounds still remain. Akira tries to get the Riders to focus on their teamwork.

To shoot a promotional video for the Scar-red Riders, the group goes to the seaside town of Shonan. While away from their usual fighting, Kazuki tries to write a song, while Takt discovers an unexpected facet to Akira's personality.

Hijiri, a transfer student with a flirty attitude, makes sport of the other Riders. When Hijiri approaches Akira, Yosuke becomes mindful of her. While fighting an enemy with odd motives, Kazuki enacts a surprising plan.

As autumn sets in, Ryukyu LAG is caught up in the excitement of the school festival. The Riders practice for their first live concert and work to promote it. Akira and Hako strengthen their friendship. LAG gets an unusual visitor.
