Mine dropped in Ulti. It has a tiny probability though. First the rainbow chest has a super low chance to drop. And within the rainbow chest there are multiple rewards, e.g. all 3 SR weapons from event exchange shop, the SSR weapon, and finally Yata Garasu. So the best bet is to farm your exchange items diligently.
