On that note, couldn't they just use other rabbits to transmit those messages?
Probably, but like Sagume said in that one doujin, "this is just a fan doujin, don't worry about the small stuff~"
At any rate.Even if it takes a while, they'll probably try to contact us.When they do, please send them an answer.That's impossible.There's no way their words can reach us over 380,000 kilometers.We're not rabbits like them.
