Looking for these manga

[Corgii]

The MC's an anthropomorphic doberman delinquent who becomes a bodyguard to a yakuza clan heiress. This is as far as I could remember it. I know it isn't much to go about but I'd really appreciate it if someone could help me find this manga.

Then there's the other one where the synopsis went like a demon queen/king being bored out of their life decided to help the hero level up and get stronger so that they'll eventually clash and the demon queen/king not being bored anymore. The demon queen/king helped the hero by disguising as a fairy. They also left like a puppet maybe so that the demon world won't go crazy at the sight of losing their leader. Also this manga happened to have a cute artsyle. I haven't read it personally, but that's what the person on the internet typed on their review of the manga on a site I can't ever find again.

and

I believe are the two you are thinking of.

Oh yes, oh yes, oh yes! Sekai Maou! So that was it. Thank you for this.

Sadly, it isn't Miss Kitty. The style resembles media from japan. They both go to school together, and the yakuza heiress wears your traditional yakuza heiress school uniform (the one with the long skirt).

I'll be adding Sekai Maou to my list before I lose it again.
