When it was all said and done, Keiko, Kaori, and Ash all leveled up multiple times. Keiko saw the least progress of course since she didn't have the same buff the Saviors had during the fight, but even she leveled up a few times.
Keiko:

Kaori leveled up as well, though not as much as Ash did since most of her focus was on keeping demons away from people, not killing them herself. In fact, most of the experience she gained came from granting Ren's dying wish. She went up five levels.
Kaori:
Level 33
MP: 60/60
EXP: 0/330
