Mnemonic
Kai-times (回) is "times / occurrences" — B + no-cluster action-count counter. Two-way split with do: kai general (concrete action) / do formal-emphasis. Sound mutation: ikkai, nikai, sankai, rokkai (gemination / half-sound). Korean beon / charye and Chinese ci / hui parallel; Japans sound mutation unique.
