Dorasu, the company that made the Hello Kitty Arkanoid game, actually makes most of their money from slot machine games. They released a Slotter Mania V: Black Lagoon for PlayStation Vita last year and Slotter Mania V: Master of Martial Hearts II back in April.

Slotter Mania V: Highschool of the Dead is scheduled to come out on October 10. The license is way better suited for an action game or Onechanbara collaboration to me.
