Rarely got to see scene of dad refusing his son to be married, usually it would be the daughter. But, beside the misunderstanding, I guess it's because he think the princess is just weird?
Miscommunication. Demons did not expect Suya to be accommodating when asked.
Also she developed liking for cells >_< I wonder if that comes to new light someday.
@ma_ko Demon Monk is like the perverted grandfather. Best ship options are either with the demon king cause he seems like a good wife material, or with Poseidon cause I just love their little banters.
When the elder demon king guy realizes just what dynamite he just refused he'll regret it. That girl will invigorate the demon king line, no foolin'.
. . . Then again, maybe he's decided HE wants her.
