Who exactly is this little sister Leo cherishes so much?
Leah, the second cat of the family of genius exorcists, joins the adventure.

She scatters specialized paint to ward off evil spirits, detonating it to wipe them out.

She is more powerful than Leo, but being a sleepyhead like a young kitten would,
she doesn't easily set out on adventures.
So, let's give her a little allowance so she can buy her favorite Dango!
She’ll be such a powerful ally that you won’t regret a single penny spent on her Dango.
