Etymology

 * The name Honoka is written in hiragana (ほのか), which has no special meaning. However, when written in kanji (和花 or 穂香), it could possibly mean:
 * 和花 - "harmony, peace" (和) (hono) and "flower, blossom" (花) (ka).
 * 穂香 - "grain" (穂) (ho) and "fragrance, fragrant" (香) (ka).
 * Honoka's surname Furuichi means "old, antiquity, ancient time, used, secondhand" (古) (furu) and "city, market, town, municipality, fair" (市) (ichi).
