Add to the list. Here is a picture of the good boy. https://i.imgur.com/jPG3gar.jpg

Yes koromaru is a good boy! I think we can all agree he is ten times better than both Morgana and Teddie (He neither makes puns nor makes you go to sleep xD)

He gets happy when you return to home as a good boy. He also has instant-kill skills.

Yes plus remember when defeated that shadow all by himself at the Naganaki Shrine?

I want to play a VR game were you give him head pats. That's it. I would be satisfied

Yes that would be best persona game: Virtual Koromaru Simulator

Persona 3 VR but just koromaru and you can pet him. That would be great with that VR setup were you can feel what you are tutching
