After meeting with the kings of various nations, Rimuru heads to Engrassia to invite his former students to the festival. The kids are thrilled to go back with him to Tempest, but then the hero Masayuki arrives as well...
That's why I busted my 
butt finishing all my work!
!لهذا ضاعفتُ جهودي لإنجاز كلّ أعمالي
Deshalb rackere ich mir
gerade auch die Hände wund.
Para eso me he matado
terminando el trabajo.
Para eso me he matado
para terminar el trabajo.
J’ai bossé comme un malade

per liberarmi dal lavoro!
Me matei pra terminar todo
o meu trabalho só por isso!
Я ради этого аж сверхурочно пашу!
