Serenity Wheeler, known as Shizuka Kawai in the Japanese version, is Joey Wheeler's younger sister. The two were separated at a very young age when their parents got divorced. Serenity is depicted as being a sweet-natured, gentle, fragile and dependent young girl. She has a small fragile body, flowing auburn (brown/red) hair, and gentle dull greenish brown eyes. Throughout the whole series she is pictured as gentle but strong, with a never changing attitude of high spirits.
Serenity's character design was overseen by Kazuki Takahashi. Serenity wears light blue denim shorts and long white socks with blue sneakers. Her top is a sleeveless pink and white shirt with a high collar that is worn on top of a short-sleeved yellow shirt. She does not change this outfit throughout the series except when she is in the hospital, where she wears simple pink pajamas. The photo Joey Wheeler has of her in his wallet shows her dressed in a sailor fuku common to middle school students in Japan. She has light brown hair and green/brown eyes
Serenity is a gentle-natured and compassionate girl who is rather dependent on her friends and seems to be generally more timid than the other females. She is also shown to be extremely trusting to the point of naivety, believing Tristan when he says, in an attempt to impress her during her recovery from her operation, that he taught Joey everything he knows about Duel Monsters. However Serenity has shown to have her own inner strength, such as when she took off her bandages to see for the first time, to save Joey by diving into the water. Serenity also after an inward struggle of self blame, was the key to defeating Nezbitt and she pulled through. Optimism seems to be one of her key features, which one would need to survive nearly going blind, being aware she may not get the operation. (Prior to Duelist Kingdom.) Serenity was separated from her older brother Joey to live with their mother when their parents divorced, but they seemed to have kept in contact over the years, as Serenity looks up to him and they both love each other dearly; during Duelist Kingdom Joey is seen to have a picture of her in his wallet. Joey often states that Serenity was his biggest inspiration throughout Duelist Kingdom and Battle City. She shares a strong bond with Téa Gardner and Mai Valentine, and Tea even takes her sight-seeing at one point.
Serenity's character is portrayed as a very beautiful young girl, capturing the romantic interests of both Tristan and Duke. This leads them to constantly argue over her during the Battle City arc and both eventually end up giving her their number. It is never shown if she ever liked either of them as more than friends, though she is always amused at their antics and even looks relieved at one point where Tristan drags Duke away from her. But she did seem to be more fond of Tristan than of Duke. Her innocent nature was even able to make one as self-centered as Seto Kaiba be considerate enough to get medical help for Bakura even during the Battle City tournament.
Shizuka is written with the kanji for "silence" and "fragrance". Serenity was chosen likely to the similarity to her Japanese Name in meaning.
Serenity and Joey were separated when she was only seven years old due to their parents' divorce, and Serenity went to live with her mother who was working as a nurse while Joey with his father who was an alcoholic gambler.
Joey receives a video tape from Serenity. In it, she tells him that time is running out for her 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, Joey is allowed on the ship after Yugi gives him one of his Star Chips. Yugi also gives him the three million dollars he won to Joey so he can pay for Serenity's eye operation.
After her operation, Battle City begins. Serenity spends most of the tournament in the hospital recovering with Tristan taking care of her. She finally removes the bandages around her eyes and sees clearly for the first time when the entire gang is sent to the Domino Pier, where Yugi and a Marik Ishtar-controlled Joey are Dueling. After Joey breaks free from Marik, he and Yugi are dragged into the ocean. Joey sets Yugi free from his shackles and Serenity dives in with the key for Joey's chains and saves him. In the manga Shizuka is present, but Joey Wheeler is instead rescued by Kaiba, who simply drops the key needed into the water. Afterwards, she hangs out with the gang for the finals and becomes friends with Mai Valentine and Téa Gardner, who both treat her like a younger sister.
Serenity's role is probably more prominent in this arc than in the others. During the Virtual World arc, she is rescued from a Mad Sword Beast by Tristan Taylor and Duke Devlin. She duels once alongside Tristan and Duke against Nezbitt, a member of the Big Five, but is not very experienced. Tristan loses the duel to protect her, sending her into a state of shock, feeling responsible for getting him involved in the first place. After a pep talk from Joey and Duke she regains her confidence and, reflecting on the basic rules she learned from Tristan earlier, barely wins, with her making the move that defeats Nezbitt. Throughout the rest of the arc she looks after Tristan who is in the form of a robot monkey since he had lost his body in the duel.
Battle City finals
Serenity was in charge of taking care of Mai Valentine, who was unconscious after losing to Yami Marik. During Joey's Duel she was asked by Ishizu Ishtar to go and see the Duel while she took care of Mai, but when she arrived, Joey fainted and lost the Duel. When the tournament ended, she went back to Japan.
One day, Téa was walking through Domino City and met with Serenity. Téa showed the city to Serenity, she explained where some Duels took place and other important events.
Post Battle City
Serenity is seen briefly in the Waking the Dragons arc, when Joey calls her to say goodbye, as well as a montage narrated by Maximillion Pegasus just before the Battle Ritual, as Pegasus says that everyone whom Yugi and his friends met was destined to play a role in his journey. She is not seen again until the last episode during the Japanese version's end credits, though in the Japanese version, she is mentioned by Tristan saying greetings to her in the Grand Championship arc when he realizes he is on live TV.

Her Deck is comprised of EARTH and LIGHT female monsters that she thought were cute. Serenity only Dueled once, in a three on one Duel with Tristan and Duke against Nezbitt during the Virtual Realm arc. Most of the cards in her Deck are from Labyrinth of Nightmare and Legacy of Darkness. In the Japanese version she mentions choosing cards that are cute (episode 106).
In Yu-Gi-Oh! Nightmare Troubadour, she uses a Deck with a similar theme, titled "Cute Sister".
