Well, I am a girl and my name is Kili-Akira. Akira isn't really my first name, but it is because it's a part of it. I really like my name. Lots of people think that Akira is only a girls name, but it's not. I know a few people named Akira and they are all boys. But people only say that the name is cute when they hear it in my name. But no one can ever pronounce it right. It is KEY-lee a-KEY-ra. That's why everybody calls me Kailey.

This is a lovely name or either boy or girl. It brings to mind a person who is happy-go-lucky; who can smile and make a bleak room bright and inviting. I wish this was my name. But hey, who says I can't name my kid this in the future?
Actually, there are no feminine or masculine endings in Japanese names (except perhaps "ko", but that's tied into its meaning). The gender of a name depends on the meaning. For example, Aimi is a feminine name because it is a combination of the elements "love" and "beauty", and Katsu is a masculine name because it means "victory".
