Tsuruchi Etsui XP: 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.
Contemplation of Destiny Open: Bow another player's target Unique Personality. If he does not have his controller's Clan alignment, permanently remove one of his base abilities or traits (not keywords).
If Tsuruchi Etsui Xp's trait is removed via Contemplation of Destiny do its effects end? More specifically, is the trait required to keep its effects going, or is it an effect that only needs to be triggered once and after that the text basically serves as a reminder?

If Tsuruchi Etsui Xp's trait is removed via Contemplation of Destiny do its effects end?
No. Tsuruchi Etsui XP's trait is not continuous but triggered (see Card features, Traits). After it has been triggered, if it targeted a Personality, its ongoing effect is applied for the stated duration: "until the end of the game", even if the trait is removed later.
