Kalifa went down one hall, while Kaku went down another.
Kalifa wasn't sure what abilities would work on Monokuma. But she had to treat this as if this were the real world and at least try.
She chased a Monokuma down the hall, using the Shave/Soru technique to increase her speed.
"TEMPEST KICK!" she called out, sending compressed air at the Monokuma she was chasing. She then hoped to follow it up with use of her Devil Fruit powers. In particular, she was going to use the Sheep Cloud Relaxing Bubbles on Monokuma.

Kaku, too, chased a Monokuma down the hall. He, too, used the Shave/Soru technique to increase speed and catch up.
Of course he had his one variants of the Tempest Kick. "Tempest Kick White Thunder!" This created an even larger projectile of compressed air, which was even more likely to impact the Monokuma he was chasing.
