It’s actually airs in Japan on Sunday mornings.
And again, Naruto and MHA are big titles over in Japan as well, they’re getting shit ratings here, but they’re still sustaining. I doubt OP is that much more expensive and clearly performance wise, at this point, I doubt it’ll do much worse.
If they can afford Naruto, and not be deterred by the low ratings EVERY SHOW is getting at this point - I doubt OP will be much of a problem. Unless Toei is randomly selling OP for a drastically higher price, even compared to other popular anime - which I find hard to believe.
