So, since October 8th looks like it'll be exciting, here's the first one.
I might forget (and if that happens, sorry, Marasai🙏💦)
When Z Gundam first aired, it was originally supposed to be named "Domingo," but it was changed due to sponsorship reasons.
The commonly held belief is that director Yoshiyuki Tomino rearranged the words "imasara" (meaning "now") to come up with the name "Marasai."
