Complete Monster: Grand WitchGrandienne deliberately sent her children out to die, brainwashed one to kill another on several occasions, banished one to Hell, and resurrected two of them as brainwashed zombies. As fitting of the family theme in GoGoFive, Grandienne stands for everything the Tatsumi family bond isn't.
The Woobie: Erika, a little girl who was on episode 17. She liked Matoi and did a lot for him, from washing his clothes to making dinner for the whole family. Matoi had to be harsh with her so she could go away from danger, which is kind of understandable. Her reaction, however, was totally heartbreaking.
Jerkass Woobie: Zylpheeza is a villainous example. He may a horrible demon, but at the same time he watches his younger sister give her life to revive him, against his will, and has to watch his younger brother die after being forced shoot him by his own mother.
Visual Effects of Awesome: It's not even that complicated of an effect, but seeing the Grandliner tower over a couple of Saimas is... satisfying.
