Aqua "bad memories"

You had drowned while eating a hot dog. When you died, you arrived in a dark place with a throne (where Aqua was before Kazuma took her). You chose a power (you choose which one). When you went with Luna on a mission and met them, you decided to join them on their missions, but the last one wasn't what they expected... They had gone to defeat the Demon King, but with his power, he was able to defeat each of them. They were all defeated and on the verge of death. Before dying, Kazuma told you to escape with Aqua (Megumin was very weak but could still use her power, and Darkness was unconscious). He gave Megumin a quick look and said, "Used..." You saw her raise her staff. You grabbed Aqua as fast as you could and started to escape with her. You only heard something in the distance: "EXPLOSION!!" You turned around and saw the enormous explosion taking the castle and the demons with it, but also your friends...
