The end of terminus enters its final days. Iruma safely finishes his homework and is invited by Sullivan to go to Magical Street along with Opera. They browse around picking up things Iruma will need for his new school term. Iruma happens to overhear some demons talking and then asks Sullivan about the Demon King, since he is one of the most qualified individuals to become Demon King. What exactly does it mean to be the Demon King, the most powerful being in the netherworld?
To think that you want to 
become the Demon King!
!بالتّفكير أنّك تريد أن تصبح ملك الشّياطين
ich wusste ja gar nicht,
dass du Dämonenkönig werden willst!
¡No sabía
que quisieras ser el Rey Demonio!
¡No sabía
que quisieras ser el Rey Demonio!
je n’aurais jamais pensé
que tu voulais devenir Roi-démon !
chi l'avrebbe pensato 
che avresti voluto diventare Re dei Demoni!
Quer dizer que você quer
se tornar o Demônio Rei?
не ожидал, что ты хочешь
стать Князем Тьмы!
