This dragon girl raising system is a bit strange.

He transmigrated into the world of a two-dimensional single-player game, becoming a villainous boss on the street. He was the common enemy of the game's three main heroines: the low-key and composed princess of the kingdom, the noble and holy saintess of the papacy, and the passionate and bold fighting dragon girl. He had no expectations of anything, only wanting to survive. He survived the subsequent major events such as the kingdom's rebellion and the Zerg invasion. Until he picked up one of the mascot girls, the dragon girl, and awakened a system. However, this system was not quite what he had imagined. [Description: In the midst of fierce battle, you have completed your meeting with Yulia. Under the fierce attack of the Zerg, you gradually narrowed your defensive line until you were back to back. You will protect each other's backs and defeat the omnipresent Zerg.] [Killed 0/100 enemy Zerg engineers (Tier 4)] [Personally killed 0/1 enemy Zerg leader] He looked at his Tier 2 self and the dragon girl Yulia, who had not even awakened her supernatural powers. Recalling the fourth-tier enemy the system had described, Thor fell into deep thought. Then, he looked at the ants by the roadside. ...Thor's day of judgment had finally arrived. Julia, who was supposed to kill Thor herself, now shielded him behind her. "Saintess, I will not allow you to kill him!"
