Party Switch allows any party member (except for the protagonist) to be switched out with another during battle. The target to be switched out cannot be downed or under a status ailment. Switching in and out also affects the EXP gain of both targets, having their result after battle cut down. This mechanic is useful in switching party members who show weaknesses to certain elements or to prevent them from being knocked out if they cannot be healed in time.
Initiating Hifumi Togo's Star Confidant unlocks the ability Koma Sabaki. Initially, the technique can only be used during the protagonist's turn. The protagonist may only switch out one ally using this tactic, and doing so will use up his turn. Maxing out the Star Confidant unlocks the Togo System, which grants all party members the ability to use their turn to switch themselves out with an ally.
If the Star Confidant has been progressed further, switched out party members can perform special Follow-Up attacks.
