A new force has suddenly risen to power in the Great Forest of Jura, and its leader, Clayman, proposes that the Demon Lords hold Walpurgis with the goal of sanctioning the slime who deceived him. Rimuru also begins to prepare for a battle with Clayman, but observing the enemy army's movements reveals that Clayman's target is not Tempest, but Eurazania. Clayman's army will arrive in Eurazania within two days. Can Rimuru's forces get there in time?
This might take a few years. 
Don't rush things, okay?
قد يستغرق هذا بضع سنوات. لا تستعجل الأمور، حسناً؟
Es könnte ein paar Jahre in Anspruch nehmen.
Stell dich da bitte drauf ein.
Puede que tarden unos años,
pero ten paciencia.
Puede que tarden unos años,
pero ten paciencia.
Ne te décourage pas,
même si ça prend des années.
Potrebbero volerci anni, sii paziente.
Isso talvez leve alguns anos,
mas tenha paciência, tá?
Конечно, на это могут уйти годы…
но ты уж не унывай там.
