A-Z with Naoki and Kotoko! A story which will contain 26 chapters, every letter one. Each chapter will show another part of Kotoko and Naoki's married life.

As if things weren't hard enough, Kotoko finds herself the sole defender of Japan against a supernatural evil. Now she has to juggle college, friends, tennis practice and fighting evil, all whilst hiding her heroine lifestyle from her super genius crush.

"Hey, have you seen that cute nurse Aihara- san? I hear she has a boyfriend. He must be such a sweet, caring guy to be with a kind hearted girl like her." On his first day of medical school, Naoki discovers that Kotoko's status as his girlfriend may not be as safe as he thought.

Naoki never heard about Kinnosuke's proposal and Kotoko said yes. As time passes, circumstances draw her and Naoki closer but she is the only one who doesn't see that they belong together. Looks like it's time for everyone else to step in.
