In order to come to terms with his own negligence and revive Shion, Gobta, and his other fallen comrades, Rimuru reveals that he used to be a human. But his allies think nothing of it and accept him regardless, as if it's the natural thing to do. Filled with gratitude for the warm, accepting environment he's in, Rimuru turns his focus to the army from Falmuth. He entrusts Benimaru and the others to destroy the devices that are generating the enemy's Prison Field while Rimuru himself sets out to attack the advancing army and use them as nourishment to become a Demon Lord.
What you were in your previous 
life makes no difference.
ما كنتَ عليه في حياتِك السّابقة لا يشكّل فرقاً
Ihr letztes Leben ist da komplett egal.
Peu importe votre vie antérieure.
Ciò che eravate nella vostra vita precedente 
non c'entra nulla con questo.
Quem foi na vida passada não importa.
Кем вы были раньше —
 нам неважно.
