New Company and mobile app logo

C'est ce que Oni Money recherchait dans leur logo design

I need a memorable mobile app logo that resembles a friendly, playful Oni taking care of Money. The design doesn't have to include the Oni itself; it can just include elements like horns or hairy elements, or an Oni mask, anything that looks professional but relaxed at the same time, friendly but secure.
This app is for financial services, so it has to transmit security and evoke good feelings about using it.
The design should not evoke fear in any way.
