Not even a really goofy accent can diminish the spectacular beauty of Ni no Kuni. That's good news! The bad news is that this first English-language trailer for Ni no Kuni: Wrath of the White Witch is all about a little boy being sad because his mother dies.
There's other stuff, like a magical companion and a potentially imaginary fantasy world opening up before his eyes, but you are going to see a little anime boy crying, and it's going to be kind of devastating. Be prepared.
