In Co-op mode, Saki's stats and passive do not change.
Saki's Hyper, Big Bang Bell, has a slightly different effect in Co-op. This trap is visible to allies, can only be triggered by enemies, and will only deal damage to enemies. The Hyper otherwise functions similarly to its Normal mode counterpart.
Saki's passive and Hyper are unchanged in Bounty Hunt mode.
Saki's base stats give her 36 starting stars and a markup of +10% at shops.
