Rimuru tries to think of a way to save the children of Freedom Academy who are fated to die. The idea he comes up with is to have superior spirits inhabit each of them, as Shizu had, so their lives won't end prematurely. Determined to whatever it takes to save them, Rimuru leads the children to the Dwelling of Spirits, where superior spirits can be found. But as they make their way further inside, a Golem made of magisteel and controlled by the fairy Ramiris stands in their path.
The Queen of Spirits fell from 
grace to become a Demon Lord!
ملكة الأرواح جُرِّدَ منها البهاء لتصبح
!سيّدة شيطان
Die Königin der Naturgeister hat gefaulenzt
und wurde zum Dämonenkönig.
La Reina de los Espíritus se corrompió
 y se volvió un Rey Demonio.
La Reina de los Espíritus cayó
en desgracia para ser un Rey Demonio.
La reine des esprits
La regina degli spiriti è stata corrotta
ed è diventata un Re demone!
A Rainha dos Espíritos decaiu
e se tornou Lorde Demônio!
Королева духов деградировала
 и стала Княжной Тьмы!
