Aotsuki Wakana (蒼月 若菜) is one of Sawamura Eijun's best friends who have known each other since childhood.


Aotsuki has short, chestnut brown hair, brown eyes and a slim figure. The managers of Seidou High find her to be cute and Kuramochi is especially surprised by her attractiveness, taking his envy of Sawamura out on him by kicking him much harder than usual. Some of Sawamura's upperclassmen are interested in seeing what she looks like.


Aotsuki is kind and somewhat quiet young woman, almost never voicing her thoughts aloud, although seeing Eijun in action always seems to make her and her friends cheer. When around or even just thinking about him, a light blush appears in her cheeks. Recently she does not always openly show her affection to him, avoiding his line of sight. (i.e. after the match vs Sensen). She's very supportive to Eijun often seeing his big matches and receiving emails from him.


Aotsuki was a member of Sawamura's middle school baseball team, as well as childhood friends. She was a right fielder with the jersey number 9. During practice she was also catching for Sawamura, as she was seen complaining about how hard Sawamura's balls were to catch. She encourages Sawamura to go to Seidou to make his dream come true and because she fears he wouldn't pass any entrance exam.

She has appeared multiple times in the stands cheering for Eijun during important games such as the semi-finals and finals of the West Tokyo Summer Tournament in his first and second years, as well as the Tokyo Fall Tournament finals match against Yakushi.

Relationship with other characters[]

Sawamura Eijun[]

Aotsuki is mistaken by Kuramochi as Sawamura's girlfriend, but Sawamura repeats several times that she is just a childhood friend and not his girlfriend. [2] Later on, Wakana confesses via mail her feeling that she want to watch Sawamura closer on his great development as a pitcher. Sawamura still has not replied to that mail.[3]

Among their Akagi teammates and before Sawamura left for Seido, Aotsuki was very practical and was Sawamura's most frank critic as far as his acedemic prospects for high school, and while her criticisms stung she was not as heavy-handed in expressing them to him as his Seido teammates often are.


  • Aotsuki means "blue, pale" (蒼) (ao) and "moon" (月) (tsuki).
  • Wakana means "young, immature" (若) (waka) and "vegetables, greens" (菜) (na).
