If my opponent uses Tsuruchi Etsui Experienced on one of my personalities:
Tsuruchi Etsui Experienced Mantis Clan • Pirate • Naval • Kolat • Experienced • Unique Once per game, after Etsui enters play or overlays: You may target a Personality. Until the end of the game, he cannot assign or move to battlefields unless Etsui is bowed or out of play.
If Etsui becomes bowed, does this effect permanently end, or does it re-apply itself after he straightens again?
Thanks,

Etsui's trait lasts until the end of the game, and prevents the target from assigning or moving to battlefields while Etsui is unbowed and in play, regardless of how many times Etsui bows during the game.
Presuming that this is potentially leading towards a followup question regarding Control, note that Control has no such wording regarding "Until the end of the game", only "while your Samurai remains unbowed and in play", so Control's effects will permanently end as soon as your Samurai bows or leaves play.
