There is quite literally zero reason for Fulio and the Demon King to be enemies with one another. Considering Fulio's character, and the King's willingness to talk to Fulio in person, I really think the two of them are going to reach and understanding very quickly. Love this manga's character dynamics!
if I recall, each of the 4 knight girls ends up with someone other then the main character, Up to the point I have read, the demon king there has more wives then the MC
Why mc is so naive?
She declared when proposed the Mock Battle, she's not planning to kill MC,
While in actual she's plan not just kill MC but also Fenrisu?and just let her go?
When she's coming back bring the dragon army and defeat her again by MC..
Better put her and any side that disturb his life out of misery..
