Serena Unabara

Serena Unabara is one of the protagonists of the Yu-Gi-Oh! Metal Revolution anime series. She is the younger sister of Shark Unabara, and is also a descendant of the Atlantean race just like her older brother.

Physical Appearance
Serena is an average tall, teenage girl with a slender figure, dark pink eyes and like her brother, she has pale skin and dark blue hair with light blue bangs. Serena also wears a grey ring on her right little finger, which was previously owned by her older brother. Her beautiful appearance attracts many admirers, including Gong.

Her attire includes a white long-sleeved jacket over a light-purple shirt, a white skirt that extends to her knees, a pair of black, ankle-high stockings and a pair of leather brown shoes with black soles.

Personality
Serena is a confident and adamant person, getting annoyed when things do not go her way. This is usually shown when conversing with her brother. Her confident personality assists in her interests which allows her to conquer sports such as soccer, baseball, basketball and boxing with ease. Despite all of this, Serena also shows somewhat of a childish side as well, shown by her fear of cats (which shows that she has ailurophobia ). Serena tends to get annoyed when people refer to her as "Shark's sister" instead of calling her by name as indicated by Evan and Cazz due to her snapping at them when he continually calls her as such, and especially does not like it when someone insults her brother. This makes her quick-tempered and impulsive, in contrast her brother's headstrong, short-tempered, sarcastic and antisocial demeanor.

Despite being occasionally irritated with Evan and Cazz for not addressing her properly as "Serena", their personalities and kind-hearted souls makes her let it slide given that she is thankful to them for helping her brother and being his friends. It is also revealed that she goes very far on things and acts strong because she feels she has to or people may use her as a shield against her brother.

She takes great pride in her abilities and effort as she has no problem in showing them when people underestimate her as she believes women are not to be viewed as "pretty decorations". Despite her tough image, Serena has a empathetic and kind-hearted quality to her personality as well, such as helping out her friends whenever they need help. She is also incredibly loyal to her brother and friends, and is willing to take daring risks to ensure their safety.
