For me the narrative for darkness consuming light takes precedence over this, not only that but Teach can always pull Kizaru in and he might even have other ways of shutting down df users with awakening from afar.
Emphasis on "crack" for this one
I always got the impression from his clash with Ace that Teach's power is more geared to countering
the sun than the light.
Tbh I think the relation between Kizaru and Teach's fruits is unclear, it's entirely possible that it's more akin to Hie vs Magu instead of a direct hard counter.
Plus what gets me is the lack of
buildup, unironically BB and Akainu have more of a connection than BB and Kizaru at this point. Like it's still viable but eh.
And I just feel like it'd be an utter waste for Kizaru to just up and die whilst being mentally nerfed again without any followup, would be as disappointing as Bertholdt just dying after he starts getting initiative in AoT to me.
Lol yeah that one was definitely one of those "Hey, this might be neat!" ideas I had. Didn't put too much thought into it.
