hareta did

I hate spoiling this for you, but yes she does against her own will because Cyrus blackmails her by saying if she doesn't kill Hereta, then he'll kill her favorite Evee. this was probably one of the most tense moments in the story line because it's the first life or death match against Mitsumi and Hereta

if you wanna know who wins keep reading....

In the end after Mitsumi completely smokes Hereta, she still has an overwhelming emotion of guilt, so thus gives up and allows Hereta to win because she wishes not to kill him along with his Pokemon.

The book of Pokemon Adventures D&P Mitsumi was tied up! (volume 6)
