When she found out from Ailwin what her sisters and Valindra were planning on doing to her. She decided she has been too nice lately.
She was going to leave Valindra alone after the match. However, since she wanted her soul to be tortured for all of eternity, that idea went out of the window; And as for her sisters....well their attention will soon be away from her for a while.
Taking Valindra's idea of redecorating, Mika made her room just as she wanted. She has no plans of getting another roommate nor of leaving the Blue dorm, she made sure of it.
As Nylian wasn't the only one who Mika berated in her letter to the Dean. She also called the school out for not teaching their students properly (regardless that she is one of their students) and their lack of security. To smooth things over with her, Dean Eolith promised that she can keep the dorm room all to herself for the remainder of the year.
