Ai

Ai is Mako's sister, and Impmon's tamer, alongside her brother.

Voiced by Rebecca Forstadt

Role
After receiving Impmon as a tamer, Ai and Mako would often fight each other over taking or breaking each others' toys, and pulled Impmon's arms to make him take their sides. From here, Impmon left them and hated humans.

When they received a small dog, they fought over it as well.

However, by the time Impmon returned, they had decided not to fight anymore, knowing this was the reason Impmon left. As Impmon left to help the tamers fight the D-Reaper, Ai kissed him. Later, she and Mako received a Digivice and became his tamers, and were introduced to the others.

Mysteriously, they did not attend Rika's birthday party, although Impmon did.
