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?
So I may eventually be able to 
become the Demon King.
.لذا قد أستطيع أن أصبح ملك الشّياطين في الأخير
Wenn ich also in Zukunft
Dämonenkönig werden könnte,
No sé si yo podría
convertirme en Rey Demonio
No sé si yo podría
convertirme en Rey Demonio
Bref, je deviendrai
peut-être Roi-démon, un jour,
Quindi... potrei finire
per diventare Re dei Demoni.
Ou seja, talvez eu pudesse me
tornar o Demônio Rei no futuro.
Однажды я и правда могу
стать Князем Тьмы.
