Nasa Yuzaki

Nasa Yuzaki (由崎 星空, Yuzaki Nasa) is the main protagonist of Fly Me to the Moon. He's the husband of Tsukasa Tsukuyomi. An everyday genius, Nasa grew up ridiculed for his strange name, similar to the American space agency NASA, although his parents meant for his name to reference the starry sky. He has a meeting with fate when he was caught in a terrible accident but was saved by Tsukasa. Declaring his love for her, on the day they met, Tsukasa agrees on the condition that he marries her to which Nasa immediately responded with an unshakable "yes". Two years later, Nasa reunites with Tsukasa carrying a marriage form which they turn in to the bureau, legalizing their relationship. Since marrying her, he becomes incredibly awkward around her, somewhat clingy to an extent because he is worried she would disappear on him again, but does his best to make her happy.
