Maika is the oldest sister of the Yoshikawa family. She can use magic, and loves cooking for her brother and sisters. She has long lilac-coloured hair, often tied back with green ribbons. She is very protective of her brother Haruo, and was immediately suspicious of Ayumi's intentions. The others often accuse her of having a brother complex, which is not entirely unjustified. As a toddler she subliminally brainwashes Haruo in his sleep by chanting "Big Brother will stay with Maika" repeatedly, and her usually caring and ladylike-personality is replaced by a possessive jealousy whenever any female shows any closeness to her brother. "Ka" means "summer" in Japanese
Karin Maaka's father, Henry Marker is a vampire who is portrayed as surprisingly human; he seems to act in a way one might call 'silly.' Despite Karin's teenage status at age sixteen, Henry still views Karin as extremely young. Despite Karin's anomalies and flaws, he still loves her dearly: this is exemplified when Karin first suffered a nosebleed at a human school, Henry braved the sunlight to rescue Karin from the hospital workers, who would have realized she was a vampire upon examination, and is severely burned in the process. Henry suffers normal paternal jealousy when the possibility of love between Karin and Kenta Usui arises. Henry is often pushed about by his wife Carrera Marker, but has a fierce side which he rarely allows the world to see. Like most other vampires, Henry has a bat as a familiar, who remains unnamed, but has glowing red eyes. (Taken from Wikipedia.org)
