@Sir LurksalotHey Avery is innocent! He simply is...ah...well...
....
....
....
Teasing? (Yeah that definitely convinced you >.>)
Also Vivi is much more polite than Vesta so it doesn't surprise me. Unlike Vesta or their parents she doesn't have an ego the size of the moon (mostly due to her rather 'lacklustre' magical abilities.
Still better than most random mages) nor is she batshit crazy like her younger sister Eri.
Also nothing like Avery. Not one bit XD
And Malakus will be polite so long as others are. Orgus is the surprise for me XD
Oh and you forgot to mention Avery beating the shit out of Rachild :P
