The possibility of Ichigo having Fullbring from birth is an interesting one, but then that could potentially raise another list of questions. Since Ichigo is as far removed as possible from a 'typical' Shinigami, he might just be able to use Fullbring from his previous status as a Visored. Or the answer might also be that because Fullbring is derived in some fashion from the spiritual power of Hollows, it would trigger a portion of Ichigo's former abilities (since his power was derived from a fusion of Shinigami and Hollow). It's still too early to say though. I'd rather wait and see what kind of abilities the Badge will grant to Ichigo after he uses Fullbring with it (and whether or not Kugo can use the Badge in his possession in a similar manner).

On an unrelated note, Riruka is right up there as the most annoying new character introduced in a new arc for me.
