The following is a list of characters from Nickelodeon live-action show House of Anubis.
Nina Martin is an American girl who lived with her grandmother in the United States before moving to Anubis House in England. Nina was the leader of the group Sibuna in the first two seasons. With the help of her friends Fabian and Amber, the three manage to hold all of the other Sibunas together in one piece. She is usually caring, level-headed, clever, and fearless, but is sometimes a little shy.
Nina arrives at Anubis House on a scholarship from the United States on the same day Joy was hidden away by the Secret Society. She obtained a locket from Sarah (under the alias of Emily) prior to beginning her adventures in solving the mystery behind Anubis House. Joined by a few of her roommates, Nina became the leader of the Sibuna club while developing feelings for Fabian. Eventually, as she and Sibuna find the Ankh Pieces after Sarah's passing, Nina learns that she is the actually the Chosen One who can assemble the Cup of Ankh. After tricking Rufus off their backs and finally beginning a relationship with Fabian, they kiss each other right at the end of the season.
In season two, she is reunited with her friends. She unknowingly lets the spirit Senkhara loose. Senkhara tells Nina that she must find the Mask of Anubis or forfeit her life. She, along with the other Sibuna members, search for the Mask of Anubis in a secret set of tunnels beneath the House of Anubis. Senkhara burns the Mark of Anubis onto Nina's arm. Nina competes for Fabian's affections against Joy, who is determined to win Fabian back after her absence last year. When she finds the Mask of Anubis, she discovers it's missing something: the Frobisher-Smythe gem! At the library, she wears the Mask and almost enters the portal, but Eddie, who is the Osirian, banishes Senkhara from her body. In the process, Nina shoots Fabian with lightning, but Joy gets hit. She almost dies, but is saved when the Mask contains the last tear of gold and Victor puts a touch of the gold on Joy's lips. At Fabian and Nina are dancing (to the song they first danced to at the end of season 1) and he reveals that their breakup was a mistake, and they share a kiss, before being interrupted in a big hug by the rest of the gang.
In season three, Nina decides not to return to Anubis House; rather, she plans to stay at home in the U.S. with her grandmother. The reason behind this is discovered to be that the Chosen One and the Osirian are not meant to be together. To continue solving the mysteries within the house, Nina gives Eddie her locket and a letter to Fabian explaining her sudden decision not to return. Eddie takes Nina's place as Sibuna's leader.
