Mika met Nakatsuka sometime prior to dating him and initially hesitated before bringing him to her house, thinking he had a girlfriend. The two later went to a club called Bronx in Aoyama, Tokyo. She ditched Nakatsuka when Sojiro Nishikado showed interest in her. However, Sojiro was only pretending so he could humiliate Nakatsuka to get revenge for Yuki Matsuoka.
Mika had dark wavy hair that fell a few inches from her shoulders. She was only seen once, wearing a semi-striped shirt, short skirt, and fishnet stockings with combat boots.
Kelly Chien plays a version of Mika in two episodes of Meteor Garden. She is renamed Mei Jia. Like the manga, Mei Jia goes on a date with Zhong Ze (Nakatsuka) to a club and later dumps him, thinking Xi Men (Sojiro) wanted to be her boyfriend.
Yoko Mitsuya portrays Mika in episode seven of Hana Yori Dango, though the character was credited as "Nakatsuka's female friend". The character goes on a date with Nakatsuka and dumps him as soon as Sojiro flirts with her, same as in the manga.
