Sensei hasn't changed her trademark tracksuit in days... that's because she's been sleeping at Umanohone in order to draw a manga for the Rookie of the Year Award! 
She changes them all the time.
Sie wechselt sie ständig.
Pero nunca olvida cambiarlos.
Pero nunca se olvida de cambiárselas.
et elle en change souvent…
Ela alterna entre elas o tempo todo.
