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?
He said his reason for proposing 
that we hold Walpurgis
قال أنّ مُبرّره لاقتراح عقدنا اجتماع والبورغيس
Der Grund, warum er eine
Walpurgis vorgeschlagen hat,
Convocó el Walpurgis específicamente
Convocó el Walpurgis específicamente
S’il a pris la peine
de convoquer le Walpurgis,
La ragione per cui si è scomodato
a convocare un Walpurgis
Ele disse a razão para propor
o Walpurgis desta vez
А Клейман Вальпургиеву ночь созвал
по другой причине.
