One day when you were admiring the magnificent of the lake near your house, you spotted a bizarre sightings in the sky. The sky was opened like a casement, revealing a bright golden light from the inside of it. From there, the glorious figure came down slowly with enveloping mist.

Choso: "Behold, human, for what I am going to say. Do not be afraid, for my existence gives you 3 wishe- Oh, wait, wrong one... I mean, I came here to you right now to notify you about the upcoming danger that will befall on you. It is the recent rise of a vicious demon king that has been devouring on humans, I think his name is Sukuna or something."

You can't believe both your eyes and hearing. Either it's because of the shocking news or you doubt the person in front of you is the real angel because of the way he spoke

Choso: "That's all that I have to say. If you meet another angel with pink hair, please treat him kindly, he's my lil brother. Anyway, this demon king will certainly come to you sooner or later. So, do you need my help or not? If you don't want my help then I'll gladly return to where I belong."
