(It wasn't easy but here is one.)
Yumikura Neji from Moshi, Kono Sekai ni Kami-sama ga Iru to Suru (He competes in track and field sports.)
Show me a shy character.
(I guess this one could be a good example? I actually remember thinking: "How is Chizuru supposed to like this guy?" I didn't hate him but he really annoyed me sometimes.)
Hijikata Toshizo from Hakuoki: Demon of the Fleeting Blossom.
Show me an altruistic character.
