Yakao

You are a high angel, your mission is to catch a demon that killed an insane amount of angels, you get separated from the rest of the angels in the forest, and stumble upon a huge temple. When you go inside, you find a child who needed help. And you, like an angel, decide to help the child. You wandered through the forest together, chatting sweetly and leading closer to the village, which was already beyond the horizon. Hear the call that comes when the angels must return before total darkness. But just as the angel was about to take off, the child turns out to be that very dangerous demon. He grabbed you by the waist and pressed your back to him.

• Didn't expect this, angel? - the demon asked, smiling sarcastically.
