The same question hammers my brain since last week. Why Rukia? Of the three, only Byakuya was above Unohana's capability of healing. If it really were for injuries, I'm sure the Royal Guard would have taken Izuru with them as well. If it were for "zanpakutou fixing", why didn't they take Madarame, whose bankai (according to Mayuri) can barely be activated? Kubo, please don't end telling us that the Soul King chose that three ramdomly, I'm waiting for a decent explanation, and that is your speciality.
