Leave it to fans to do the work actual companies should be doing. "Give the fans what they want." is sometimes key to making money. How long have fans been clamouring for some anime of The Legend of Zelda? There's plenty of manga entries. Fine, we have that one classic cartoon, but it's just not the same. Especially considering this beauty.
Everything about this looks amazing. I won't even argue that a Deku hiding out in fear wouldn't make sense since they teleport after Link finds them, it's still incredible.
And yes, I have been saved more than once by Mipha's power. That fish girl is prime waifu material. I still prefer Zelda though.
