The entire manga features people becoming very surprised finding a small goblin who is supposed to be just a weak enemy you meet on the way, but it always turns out in her case, that their assumption about her is far from true.
The most interesting thing is her empty expression through it all, she is adorably thoughtful and each chapter of Goblin Is Very Strong Manga is extremely interesting as it features the young goblin either jumping on unexpected heroes, running them into trouble or generally just having a blast at the sight of their misery.
