カタカナ -> Dakuten & Handakuten . Surprised to see Katakana ぼいん"ウ" has Dakuten(ヴ) that represents "vu" sound, and above that seems Katakana has more combination kana compared to Hiragana. I understand that more and more combination kanas used to enrich the japanese sounds for their loan words. Fingers crossed. 居味がある ✨
