Ben and Ichigo have a very good relation with each other, with both fighting together effectively.
Ichigo sees Orihime as a good friend, and cares strongly about her. He even goes as far as disobeying the head Captain's orders, in order to rescue her. Orihime, in turn, has a crush on Ichigo, though recently she's been developing a bond with Ulquiorra.
