How I usually grind levels for my familiars in this game

Just another random video post I'm doing on a whim.
Don't get used to it.

Got TONNES of Sake and Sushi as a side note.

The levels stopped rising quickly after the familiar in use hit level 30.

For obvious reasons, I just want to raise the Sword Familiar's level to at least 50.

I-it's not like I was doing it for the clicks... baka...
