I became a half-dragon swordsman mage after being a stunt man!

Suddenly looking away from his smartphone and checking ahead, there was a little girl right in front of him about to be hit by a truck. Only he noticed it. Thinking "This is my moment!" he rushed to help with great enthusiasm, but unfortunately, Sato Rei stumbled over a stone and fell. He managed to push the girl out of the way, but he himself got hit by the truck! The last thing he thought was, "In my next life, I want to be born in a fantasy world of swords and magic!"... What a quick change of heart! And so Rei died... or so he thought. A god who had witnessed everything was moved by his actions and gave him the opportunity to be reincarnated... His previous occupation was a stuntman! Overwhelming magical power against thieves!? As for his titles, the lineup is full of surprises! There's no way he won't become strong!!! This is a story where a protagonist who prioritizes "cuteness equals justice" does as he pleases, resulting in a harem. Thank you very much! \(^o^)/
