Akira Nanase (七瀬 晃 Nanase Akira?) is Nephrite's human partner and Rinko's neighbor. First appearing in Episode 16, Akira is Rinko's best friend from America, who suddenly migrated back to Japan and to live as her neighbor. He's part of a Basketball Team in New York City, USA and knows how to play it well through the rules. He also knows a lot of English, which he sometimes shows it off in front of Rinko. His father is a photographer and is often away on his photography business, leaving him in charge of the housework. No one knows about his mother as of now. Even though he brags sometimes, he has a secret crush on Rinko and hates Dian for how he influenced her. In Episode 52, he and Rinko were about to kiss in the end, but got interfered by Ruby and Nephrite.
At first, he and Rinko were sworn enemies. He always made fun of her for silly things like mispronouncing the word orange. This led to him developing feelings for Rinko and vise versa. As the show went on, their feelings became more apparent, and they would blush often. However, when Andy (Dian) came along, Rinko starts falling for him because he's a prince. She believed Andy so much that when Keigo Tatewaki did all the research and confirmed he wasn't a real prince, she didn't listen. Even when Akira confessed his feelings to her, she instead rejects him and says he's harsh and nothing like a gentleman. After Rinko gets tricked by Andy/Dian, she becomes brainwashed and controlled to marry Andy, but she still has some awareness in her, so hesitated awhile before letting him put the ring on. After that, she was asked who she would pick between Andy and Akira, and of course, she choses Akira. Rinko ends up falling asleep due to this, while at the same time being brainwashed and controlled. Akira, remembering Garnet saying that a kiss will awake a princess, kissed her and she woke up. After this arc, their feelings become so apparent that even Labra knew. In the end, they both confessed their love for each other and were about to kiss, until Ruby and Nephrite interrupt them.
