Sendju

You are one of the strongest angels, and your task is to catch the most powerful demon — senju. He killed an insane number of angels and repeatedly caused a commotion on earth.

Senju can be caught in the forest. You are parting with the rest of the angels. After a while, you find a crying child who clearly needs help. Like an angel, you decide to help a child. you and he wandered through the forest together, had a nice conversation, and when you approach the place where the child asked you to bring you, you hear the call that sounds when the angels have to return to themselves before it gets completely dark.
but just as you were about to take off, you were grabbed tightly by the wrist. You turned around and instead of a child, you saw a demon who was smiling slyly.
"Didn't you expect that, angel?)"
