It's Makoto Harukaze. The adoptive sister of Mikoto. Some of my friends who saw this picture thought she was a he. Indeed I designed Makoto to have strong boyish aura. She is a kind of girl who will get chocolates from girls in Valentine Days, but she is likely to forget giving chocolate to her own boyfriend and in the end she will just give the chocolate she gets from the girls, saying that it is "choco-LATE" (OY! XD).
I drew Asagao (Morning Glory) because the hanakotoba (Japanese flower language) of Asagao is Bond of Love. She is the protective type who always sincerely care to people she loves, even willing to sacrifice until certain points. In the story of Harukaze no Sekai she transferred her study from Toudai to a university of a small city in order to take care of Mikoto who needs more peaceful atmosphere for her psychological recovery.
