The ring announcer in the Arcadion says

初戦の相手は、「ブラックキャット」!
The first opponent is...BLACK CAT!

生身の挑戦者は、怪猫の魂に対抗できるかア ! ?
Can this flesh-and-blood challenger overcome the soul of the kaibyō!? (Monster-Cat)
Which has got me curious about, like...are "flesh-and-blood" challengers a novelty?

Is this related to the SOUL SIPPY kiosk...?
