One of gaming's biggest mysteries is why this franchise isn't popular in Japan. Like, it has everything that should appeal to the japanese marketing, the anime aesthetic, the cute pixel units, it's colorful, the soundtrack is amazing, and it's a turn based strategy game ffs.
I know the first GBA game had to be delayed and blablabla but really, I think it's just a matter of rebooting it and marketing it right, so it really is a shame that this isn't getting a Japanese version, it was the perfect opportunity.
