As of April, 2018, Kubota announced that she would not continue as a member of Kalafina. While Masai and Ootaki will continue working under Sacra Music, it is unclear whether they will continue as a duet under the name Kalafina as a claim for the trademark was filed by Kubota in December 2017. It is unknown if this was filed with the intention of keeping the name Kalafina and working with Kajiura in the future.
