This announcement causes major uproar among her fans.  After several
hours of wild guesses (sickness / retiring / pregnancy / becoming a
parliament candidate / etc), an online news agency got hold of King
Records, and found that the reason is not related to sickness /
retiring / pregnancy.

Sources said there is a continuous argument/disagreement between King
Record and Yikari in the recent months, so her contract, which will be
expired on 2016/03/31, will not be renewed.

absorbed back into King Records on 01 Feb 2016.  Star Child ceased to
