Yoshiyuki is the protagonist of Da Capo II as the student of Kazemi affiliated junior high class 3-3. He is the son Sakura and Jun’ichi never had, brought into existence by the new unwilting sakura tree. His name refers to this as well as it can be taken to mean “Yoshiyuki born from within Sakura.” Like Jun’ichi, Yoshiyuki can create wagashi with magic. He also appears to be able to see either the future or people’s desires and dreams.
When he himself is asleep, as shown when at the beginning of a couple episodes where it shows a dream he is sharing with someone and later when the actual event occurs and he recognizes the relation between the reality and his dream.
In the anime, Yoshiyuki is depicted to be very caring about people around him. His actions as such frequently results in girls misunderstanding his helpful nature as signs of confession.
Yoshiyuki is very insensitive to the people, especially the feelings of girls surrounding him.
It is also not clear who he habors feelings for even though he accepted Koko’s confession and even dated her in the first season.
