Players are able to swap a Kami in their party for a random Kami in the Vending Machine Gacha Pool. This is referred to as "Re-rolling" a Kami and costs one Re-Roll Ticket.
Players may choose to re-roll a Kami for a variety of reasons, such as:
Seeking a Kami of a particular Type or with particular Traits.
Punishing one of your current Kami for bad behavior.
Re-Roll Tickets are auctioned in-game at the Vending Machine, much like Gacha Tickets. However, Re-Roll Tickets are priced in $ONYX and have an infinite supply.
