Hana Ishimoto:

A major character; part of the main ensemble. Hana is a 1st year at Bura Bura Academy. She is the Vice President of the Gardening Club... Well, because there are only three members at the moment. 

Hana is not-so-secretly in love with Shiro Ishida! She attended Shiro's elementary and middle school but was too shy to speak to him after he helped her find her class when she was in the 2nd grade.

Shiro does not remember Hana when they meet again in High School.

Makoto Hamada:

Makoto is the President of the Paint Club and a friend is Shiro's from middle school. She is hot-headed and territorial when it comes to Shiro. She dislikes anyone who takes up his time. Makoto hates Keiko because of her attitude and unknown history with Shiro, but other students have said Makoto and Keiko's personality are quite similar.

Makoto's cousin, Susumu Hamada, is the Gardening Club President; Makoto volunteers The Paint Club to help promote Susumu's Club and get him more members.

Makoto can be spiteful and rude, but ultimately she has a good heart and cares greatly for Shiro.
