The Mr. Bushido nickname is the first canonical instance in One Piece of a cross-organizational-language-bleed becoming a permanent character-address. The pattern is the carried-over linguistic register persists doctrine — a character internalizes one social-context’s naming grammar and then carries it forward into all other contexts, and the carry-over is permanent.
Per Volume 23 SBS, the nickname is canonized as lifetime-permanent:
The lifetime-permanent canonization means every later Vivi-Zoro encounter re-keys to this Ch. 0109/0110 install:
Reverse cover-arc Vivi-Zoro encounters
Whole-Cake-Island Vivi-escaping-with-Morgans period
Post-Final-Saga Alabasta-defense
Any final-arc Vivi-Zoro reunion
Why the 0109 + 0110 dual-seed matters
The Ch. 0109 install is the coinage (under combat-opponent register, under-disguise); the Ch. 0110 re-invocation is the persistence-test (under ally-petition register, after princess-reveal). Both are required to lock in the lifetime-permanent doctrine:
If Vivi only used the nickname during the combat-encounter (Ch. 0109) and dropped it post-reveal, the address-pattern-bleed would read as situational, not permanent.
The Ch. 0110 re-invocation in a completely different social-context (escape-petition, not combat) confirms the nickname has entered Vivi’s persistent linguistic register — it is no longer Baroque-Works-internalization but Vivi-internalization.
The SBS Vol. 23 canonization confirms what the Ch. 0109+0110 dual-seed empirically demonstrates.
