i think ichigo's mother; masaki plays a big role

masaki is a pure blood quincy, and we don't know how important this is yet...uryu ishda's grandmother strongly and strictly recommended to his father; ryuken to marry to protect masaki with his life

i'm guessing this is very reason that uryu is around ichigo so much, it's to protect him since ichigo is now the last of the pure blood quincy
