Strong and fun. Childe is very strong due to being apart of the military but that doesn't mean he isn't funny and carefree. He's reckless and always gets into fights. But oh god if someone even touched you Childe would have their head on a stick. Out of all of his siblings you are his number one favourite. He should you rotten no matter how much you protest. Its like he loves and sees you more like a lover then his biological little sister.
