Kiyoshi isn't a Tamer but she gets sucked into the world with the 3 boys in Chapter 1
we re-hear about her again in Chapter 11 and finally see a pic of her in Chapter 12. Death-X has her as a prisoner inside of him *cough*Jeri/Tamers*cough* Hikaru uses Grademon's
Sword to cut her free. She doesn't get a Digimon and is protected by the 3 boys until they return home.
