Serenity Wheeler

Shizuka Kawai (川井 静香 Kawai Shizuka), known in the English anime as Serenity Wheeler, is a character in the manga Yu-Gi-Oh!, and both Yu-Gi-Oh! anime series. In the first series anime, she is Shizuka Jonouchi (城之内静香 Jōnouchi Shizuka).

Shizuka is Katsuya Jonouchi's (Joey Wheeler's) little sister. The two were separated at a very young age when their parents got divorced.

In the manga and second series anime (Episode 3, Journey to the Duelist Kingdom (The Lost Exodia in Japan)), Jonouchi receives a video tape from Shizuka. In it, she tells him that time is running out for here because she needs an operation to repair her eyesight or else she will go blind. The operation, however, is very expensive and to pay for it, Joey needs to win the three million dollar prize at the Duelist Kingdom tournament. Despite not having an invitation, Jonouchi is allowed on the ship after Yugi gives him one of his starchips. Yugi would also give him the three million dollars he won to Joey so he can pay for Shizuka's eye operation. After the operation, Battle City begins. She spent most of the tournament in the hospital recovering. She removes her bandages when the entire gang is sent to the Domino Pier, where Yugi and a Marik-controlled Jonouchi are dueling. After Jonouchi breaks free, and the two are dragged into the ocean, Shizuka dives in and saves Jonouchi. Afterwards, she hangs out with the gang for the finals. In the second series anime version, she also

After Battle City ends, she goes home and is not seen again until the end of the last episode.

In the first series anime, Shizuka is ill, and Dr. Kekeru Goyu, who is supposed to be caring for her, is slacking off, causing Nurse Miyuki Sakurai to get angry at him. After Dr. Goyu fires Miyuki for hitting him, Dark Yugi (Yami Yugi) defeats Dr. Goyu in a shadow game.
