In Co-op mode, Natsumi's stats and passive do not visibly change. However, part of Natsumi's passive functions differently:
- At the end of Natsumi's turn, if not KO'd and if standing on the same panel with other units, each player on the panel recovers 1 HP. This is similar to how her passive works in Normal mode, but does not apply the healing effect to enemies.
Natsumi's Hyper, Cooking Time, has a slightly different effect in Co-op. The hyper only heals players and does not give stars, but otherwise functions similarly to its Normal mode counterpart.
Natsumi's passive and Hyper are unchanged in Bounty Hunt mode.
Natsumi's base stats give her 50 starting stars and a discount of -25% at shops.
