Rokuro has sworn to defeat Yuto. But... how? The Twin Star Exorcists look at the facts and try to find a way to strengthen their odds against an opponent that outclasses them in nearly every way.
The more regrets you have, 
the more they will bind you.
كلما ندمتِ إلّا وقيّدك ذلك أكثر فأكثر
Deine Reue wird
dich immer fesseln.
Cualquier lamento que tenga, la atará.
Cualquier lamento que tenga, la atará.
Les regrets n’auront de cesse
de vous tourmenter.
I rimpianti si accumulano l'uno sull'altro
e si fanno sempre più pesanti.
Quanto mais arrependimentos tiver,
 mais eles vão te amarrar.
Чем больше у вас сожалений,
 тем сильнее они свяжут вас.
