Let us discuss the poll included in this thread.
For me, I would choose Hanamichi Sakuragi but Harima Kenji comes to a close. Both of these characters had changed because of...well...love. I really like Sakuragi more because of his attitude as well as his skills. Harima however, is really admirable since his love for Tenma-chan is really strong and true. I mean he really changed a lot!
Seiji Sawamura is good too but I still like both hanamichi Sakuragi and Harima Kenji than him X-P
