Nina is serious, determined and hard working because she wants to win the love of her adoptive father Sergay. Nina holds mixed feelings towards Arika Yumemiya. She is jealous of Arika's connections with Sergay and often annoyed with her cluelessness, but she shows friendship towards her on occasion. Nina's friend, Erstin Ho, was also her roommate who was in love with her. This was most evident during episode 6 where Erstin performed CPR on Nina in a rather affectionate way, leaving Nina embarrassed. Image:Name.gif
