ChiLumi

Chilumi is the het ship between Childe/Tartaglia and Lumine from the Genshin Impact fandom.

Canon
Lumine first meets Childe in 'Archon Quest Chapter 1 Act 1'. Lumine is escaping to avoid suspicion of being the culprit of Rex Lapis' murder. When she was at the stairs she stepped on shard of glass accidentally grabbing the guards attention. Unfortunately, she gets surrounded by the guards until she hears Childe's voice saying "Hey girlie-- Hold still," or in the JP dub Childe calls Lumine "ojou-chan". Childe then knocks all the guards unconscious and escapes with Lumine. After both Paimon and Lumine are exhausted from running, Childe formally introduces himself. Of course, that wasn't his real name but an alias of sorts. Paimon and Lumine figured that Childe is one of the Fatui. Childe claims he isn't here for trouble, but is here to help them. Childe trust Lumine for not killing Rex Lapis since he's been keeping eye on Lumine. Childe has gave Lumine a fake Sigil of Permission created by the Fatui, and the story continues.

Fanon
This became a ship by the fandom seeing their relationship between each other by then, fanarts, comic dubs and fanfictions has been created by it. It also resulted about lots of them which means it has became a popular het ship in the fandom.

With the ship Aether (Lumine's brother) is portrayed as very overprotective of his sister. Same goes with Childe.
