THIS IS NOT MY OPINION, THOUGH I AGREE WITH SOME POINTS

There are no serious pointers that shows us whether Ichigo would be with either Rukia atau Orihime. However, I personally choose Rukia.

Orihime is beautiful, feminine, soft with a kind heart, damsel in distress type; basically, the 'perfect' no-brainer pairing for the hero, Ichigo.

However, Rukia's no pushover either: she's smart, calm, composed, pretty with a sense of responsibility of who and what she is as a shinigami, sister and friend. Not to mention, she is loyal to her friends and she is willing to stand up for what she believes in....
