After being confronted by Yuuto, the Twin Star Exorcists are desperate to get stronger in preparation for future battles, but Benio's old master Subaru has a different kind of training in mind.

يا لها من ذراعٍ جامحة
Was für ein wunderlicher

Que braço rebelde ele tem.
Какая же непокорная у него рука.
