Hmm, I've always thought of character names as interesting topics, especially for authors and creators such as ourselves. Well, I prefer unique and one of a kind names, but I also like it when they're easy to remember. Like memorable but unique names. Examples of these kind of names are Zylith, Verose, and Zelan from Freaking Romance in Webtoons.
But if you'd ask me how I come up with names for my novel's characters right now, my novel is set in Japan, so therefore, my characters' names are Japanese. But you see, in my opinion, Japanese names are quite interesting and they fascinate me, because they have meanings behind them. Kind of like etymologies.
For example, in my novel, one of the protagonists' name is Mayumi, and her family name is Sakuragi. Mayumi can be written using different kanji characters (a kind of Japanese writing), and it has quite a lot of meanings. It can mean elegant, gentle, beauty, truth, reason, or spindle tree. Her family name, Sakuragi, can mean cherry blossom tree. I guess you could tell that I researched a lot to name my characters!
