I'd say its on purpose, names in manga and books usually are. Just like you said, they carry meaning and the authors chose them specifically. Sometimes its illustrative of the character's personality, sometimes its like flavor text - it adds interest and color to the stories, and sometimes its as a tribute to someone in their lives.

That's Finnish name! Means Sea breeze. I wonder.. Was it meant to be so or just accident? Kind of like Kieli novels (and manga). Kieli means tongue or language in Finnish but I get it how it end up as a name.. It does sound beautiful.
