Kairi is a spoiled, whiny damsel-in-distress. She is not determined and useless when someone she cares about is in danger, as she always puts herself in harm's way to help Sora when he's in trouble despite her not appreciating it. She is said to be getting more useless and much less independent, but despite still being whiny, Kairi's heart is said to be filled only with pure light and goodness.
Aside from a slightly bigger bust, Kairi appears a little older than in Kingdom Hearts 3.
Being unable to stop Empress Hazel from defeating Sora and Riku and taking them off-world, Kairi is naturally heartbroken upon hearing Hazel has declared them both dead. She was later confronted by Sarah, who, despite roasting Kairi for her weakness, shares her refusal to believe Sora is truly gone, and they are shortly both met by GOTHOH, who confirms neither Riku nor Sora are dead. With renewed hope, Kairi wanted to accompany GOTHOH to Neo Asgard-III, but Sarah tells her to stay on Destiny Islands and "wait like the useless, whiny creep you are."
- Kairi was supposed to have her own story arc in Superhero Keyblade Wars, focusing on getting herself out from under her friends' shadow and encouraging Ignis to move on from his horrific past.
- Kairi's role in KH DP and absence in KH TTR, despite still being mentioned in the latter, were played out in with Sarah Cowan's opinion of her in mind.
