Aria: The Scarlet Ammo

Kinji wants to be normal, but his secret condition makes student's desire to make him their partner.

Aria tries to strong-arm Kinji into teaming up with her—by threatening to live in his room until he complies! When he fails to shake her, the two end up on a cat caper. Later, Kinji decides to investigate the transfer student’s background.

Aria shows her cute side when she follows Kinji to the arcade after school. Later, when a bus full of Butei High students is hijacked, Aria calls on Kinji to team up with her to save their classmates.

Kinji trails Aria through town to the police station where he learns why she’s so desperate for a partner. When he finds out she’s flying back to London, Kinji realizes she could be the Butei killer’s next target!

Aboard a quickly descending jetliner, Kinji corners the Butei killer, who makes an explosive escape—but not before inviting him to a secret organization. As Kinji and Aria try to land the plane safely, they get some unexpected help—and interference.

Aria volunteers to guard Kinji's friend: Kinji gets caught in the middle of a constant cat-fight!
