Yuuki is saddened by the death of Clayman, and Luminus is saddened by the death of Roy. Steeped in sadness, and having lost their friends, they seek their next move against Rimuru, who has grown in power and become a true Demon Lord.
He died 'cause he got cocky and 
ignored the warnings despite being weak.
مات لأنّه اغترّ وتجاهل التّحذيرات
رغم كونه ضعيفاً
L'abbiamo avvisato del pericolo, e lui ha fatto 
il gradasso nonostante fosse debole ed è morto!
Ele morreu porque foi arrogante e
ignorou os avisos, apesar de ser fraco.
Он был бараном и слабаком,
так ещё и советы слушать не хотел!
