Here some infos I found on the internet about the accident:
2006.03.20 Aikaryu encounter a car accident on the way home from a live. Kaworu sustained the least amount of injuries, while the rest had to remain hospitalised for a while. Teru had chest pains and bruising here and there, Daiki also had bruising here and there as well as deep bone-bruises, Shagrath and roadie Sano sustained head injuries (but both are fine now), and Uli sustained two broken legs.
and
2007.04.29 Aikaryu announces that they will disband on 2007.07.15 at Kyoto ARC DEUX. The reason behind this is that Uli, though recovered enough to walk, still cannot play the double bass drums and can only barely play the single bass drum and only for a limited time, and Aikaryu didn't want to go on without him.
