Eudial was the first of the Witches Five, and had a special gun that can shoot out the pure heart from people.

Eudial used her computer and found out that Uranus and Neptune were the ones who had the talisman. She set up a trap for them and got the talisman, but Sailor Moon came by and defeated her.

Eudial died as Mimete had rigged her car and took out the brakes.
