My tastes in many different areas seem to fall more into a niche category than the wildly popular categories.  Manga is one such example.   

As such, I have read and enjoyed several different manga titles that seem to be less well-known among manga fans.  I have included here a list of most of these manga titles.  I'd be interested in discussing any of the following such titles here.  So if you've read any of them, please state which one(s), and we can discuss them.  And even if you haven't read one of these titles but you're curious about it, then also say so.  I'm willing to be flexible here.   

A,A' (A, A prime) by Moto Hagio
Clover by Clamp
Mai The Psychic Girl by Kazuya Kudo and Ryoichi Ikegami
