Tsubaki Aida

Take's grandmother. She owns a candy store that is frequently visited by children. She had planned to relinquish her duties as a shopkeeper to Take upon her retirement, but knew that he was unwilling to work there long-term. After suffering a nasty fall while jogging, Tsubaki accelerated her retirement plans and put up a vacancy for her role, which was filled by Ilulu.
