Sigfrey is on a mission to steal the gold from a dragon, he takes advantage of the fact that the dragon is asleep, but when he gets close to the dragon he chickens out and leaves without the gold. In his flight he hears a scream of a girl, and this is enough to wake up the dragon, Sigfrey and the nearby monsters that were going to attack him see that the dragon wakes up and everyone is scared of what can happen. The dragon takes one of the monsters and swallows it in one bite, the other manages to flee but Sigfrey is unable to move.
At that moment he sees his life passing and gets some courage and attacks the dragon which does not receive any damage from his attack, but at that moment, Sigfrey stabs the dragon without trying, a big explosion is heard and a naked girl with wings and claws falls on him.
When she sees him she moves away and tries to growl to scare him but she realizes that her form has changed, she asks Sigfrey to return to normal but he tells her that he doesn’t know how to do it, and gives her the dagger so she can find out and gives her the address of the guild so she can go to find out what happened. He then tries to leave, but the dragon tries to stop him by telling him that he must take responsibility for what he did, but he still leaves.
