Arima returns to Tokyo to give the Twin Star Exorcists a trial to test their skills. But it's not the kind of test they were anticipating, with an unexpected reward.
He sacrificed himself to protect his comrades.
وقد ضحى بنفسه لحمايتهم
Um seine Kameraden zu beschützen,
sacrificándose para protegerlos.
sacrificándose para protegerlos.
Il se serait sacrifié
pour protéger ses camarades.
Si sacrificò... per aiutarli.
e se sacrificou para protegê-los.
Он пожертвовал собой 
ради защиты товарищей.
