Clannad: Mou Hitotsu no Sekai, Tomoyo-hen, Kaichou wa Maid-sama! Recommendations
Both have female characters that are boyish on the outside but are really sweet on the inside. Both are class presidents and really care about the students at the school. Both are really strong. Misaki is kind of a combination of Kyou and Tomoyo from Clannad though is more similar to Tomoyo. Tomoyo and Misaki both have a love interest who would do anything for them. Clannad is a lot more serious while Maid-sama tends to be more light-hearted but still has its serious and romantic moments.
