Leorio

Leorio can be found near Beatrice's house. He is the fursona of Leorio Starvinski, the composer of most of the songs in the game. He can be recruited by completing the annoying bullshit fetch quest triggered by giving vodka to Emily.

His quirk in battle is playing music to produce various status effects.

The game itself describes him as:

"The sickest music producer of Straight Down City."
