Shizuka

Shizuka is one of the 4 girls Arashi has entrusted Ryouta with under suspicions of evil activity in the Other World. Since she was only risen with the other 3 girls as humans (or were believed to be) around her, she despises humans a lot, though this could have been picked up from Arashi.

Appearance
Shizuka looks like an 8-year old girl with brown hair and bright green eyes. She usually wears the same school uniform she wore back up in the Other World. She looks exactly like her younger sister, but her attitude and dark atmosphere around her is what is a dead giveaway of which one she is.

Shizuka and Sakura's Death
The twins were both with Ryouta and Scott's group. Malicious Revenge, to make the two furious, killed off the twins with a Death Note.

Relations with Others
Shizuka despises humans and often doesn't associate with them, but has a few relations though.

Ryouta: Ryouta is given the task to watch over her, but at first, the two didn't get along that well. She despised him for having to be a babysitter for her, but overtime came to see the true him and fell in love with him. She tries to keep these feelings hidden but Sakura always tries to make her say her love out loud. Finally, during the Halloween OVA, the two confessed their feelings.

Sakura: Shizuka's twin sister. These two are always having sibling rivalries but deep down the two greatly care for each other.

Rina and Hana: Though they never converse that much with each other, these two were some of Shizuka's friends back in the Other World.

Arashi: Shizuka tended to see Arashi as a great caretaker until Arashi flipped out about the musicbox ordeal and now she really doesn't even acknowledge him.

Scott: Shizuka shows a great deal of respect towards Scott as he is a wealthy business man unless he's always helping Sakura pick on her and Ryouta.

Kuro: Shizuka sees Kuro like Arashi and how the two have a quick temper of things.

Decks
Shizuka uses a Plant Deck, which focuses on swarming the field and summoning Black Rose Dragon. However, Black Rose Dragon lost its Signer powers so Shizuka is not one of the 10 Signers.
