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.
Anyone with a brain would choose 
coexistence over hostility.
أي شخص له عقل سيفضّل التّعايش
على العِداء
Sollten sie Verstand haben,
werden sie das Überleben dem Kampf vorziehen.
Si son inteligentes, preferirán
convivir que pelear.
Si son inteligentes, preferirán
convivir que pelear.
S’ils sont malins, les humains
préféreront la paix à la guerre.
Qualunque creatura dotata d'intelligenza sceglierebbe 
di coesistere, piuttosto che di esserci ostile.
Aqueles que forem espertos escolherão
a convivência em vez da hostilidade.
У кого хоть немного ума,
 тот предпочтёт мир войне.
