It's an isekai manga about a boy who is headed to another town with his family and their friends when they are attacked by bandits. While being attacked he has to help his dad protect his mom, who can't use her magic properly because she is pregnant. While protecting her, he has to sacrifice himself to stop the last bandit by throwing him and the bandit over a cliff. A mysterious force saved him from dying when he fell over the cliff and he found out the mysterious force was a dragon, but at the time of meeting the dragon he couldn't tell it was a dragon because the dragon looked... odd.
After the dragon was able to send him back to his parents, the dragon died and upon dying she embedded her will on him. Now that he has the dragon's will and is in the forest he comes upon a group of human traffickers that are kidnapping an elven princess. He saves the princess and takes her back home, but her grandfather takes a liking to him and decides to train him...
Does anyone know the name of this manga? I think it just recently became an anime as well.
