Awesome! I loved it!

"Nothing could possibly tear the loving bond between these two brothers apart… All except for "
Oh...too soon after the OVA's...too soon...

This is great. It's really fun, and made me laugh. Thanks for the great work!

Love. This. Opening. Really witty.
But you sometimes forget this is a fantasy world, with its own names for months, and no tabletop RPG (probably?), sooo... Sapkowski can get away with batist panties on his princesses, but this only goes so far, okay?

The "near-serene" paragraph is a bit too much. Depurplify. And - Adamai is shockingly nice and unselfish here. I know he's had eight years of character growth, but... this puts my Adamai in bad light ;). He couldn't "prepare for his long-awaited plans", plans are prepared for in advance by definition. And it's "heads" when talking about many of these. Also - commas are there to give the reader breathing pauses. Read things out loud to find good places for them.

Oooh... Reading along, I take back the "nice and unselfish" comment. Bad dragon, bad :) "That could have been horribly" - horribly what? Alibert must be doing some sort of Mary Poppins potion, seriously. Yet again, you wrote him as a preternaturally good parent.
The customers being used to Yugo's cleaning methods could stand being shown, instead of told (maybe a short dialogue?)
And - ooh, the little rascals!

Bottom line: really cute. Really, really cute. With super-dad Alibert. Yay!

SCREAMS

Im so glad you went through and posted it!

I dont know if i said yet or not but i absolutely love the pranks- i mean adamaï's are a little intense which fits him so well since even in the show he goes a little too hard for humans, and yugo's escalating a bit each time but still being less risky.

Alibert is such a stern dad o_o but hes really caring about it and its a neat light for him.

Good silliness and Alibert being the voice of reason when they go too far vry nice
