Question:

I'm pretty sure it's Japanese but my friend is claiming that they're certain it's Spanish. They said that I wouldn't know because I don't speak Japanese, but even though I don't, isn't it still possible to recognize an accent?

it's the blue character with the mask

I'm just curious btw. I know it's not that important of a question but I'm just wondering.
