When Gura says "shaaark" is it supposed to be a reference to something or did she just come up with that on her own?
There was an old video game I played called Granblue Fantasy where the sharks would always say "shark" but I doubt it's a reference to that. But seeing it in more than one place just makes it all the more confusing to me.
Why would two separate and unrelated things come up with the idea for a shark to say the word "shark" instead of making an actual shark sound?
