Manga names don't have to be Japanese. They can be in any language or a combination of languages that make sense for the story and characters. It all depends on the author's vision and creativity.
Well, a lot of Japanese names have meanings related to nature. For example, 'Sakura' which means cherry blossom. In Japanese culture, cherry blossoms are symbols of beauty and transience. They are highly cherished, and many girls are named Sakura to embody that beauty. Another example is 'Haru' which means spring. Spring is a season of new beginnings in Japan, so the name Haru can represent freshness and hope.
Well, 'Mika' could be an elf name in Japanese novels. Japanese novels sometimes combine local naming styles with fantasy elements. 'Mika' is a simple and sweet - sounding name that can be used for an elf character to show its more approachable side.
One way is to consider the meaning of the names. For example, if your story has a theme of nature, you can choose names like Mori (forest) or Kawa (river).
One way is to use common Japanese female name elements. For example, 'ko' at the end of a name often indicates femininity, like Sakura-ko. You can also combine nature - related words with these elements. For instance, 'Yuki' which means snow, can be combined with 'ko' to form Yuki - ko. Another tip is to look at traditional Japanese family names and use parts of them to create unique first names.
Some common Japanese names for a story could be Haruki. It gives a sense of freshness and youth. Another one is Sakura, which is associated with the beautiful cherry blossoms, representing beauty and transience. And there's also Taro, a traditional and simple name that can be used for a male character in the story.
You can start by looking at traditional Japanese names and their components. Pay attention to the syllable structure and common endings. For example, names often end with -ko, -mi, or -yama. Also, research Japanese words related to nature, virtues, or colors and incorporate them.
