Kaito commonly joins the kanji for “sea/ocean” with “soar” or “fly.”
Japanese given name read as 'dragon man' when written with a dragon element plus 'o/man', e.g. 竜雄 / 龍男 (竜/龍 'dragon' + o 'man/hero'). Hedge: strongly kanji-dependent; some spellings use 達 'attain' or other elements with no dragon sense, so only the 竜/龍/辰 writings genuinely mean dragon.
