Childe

Falling into the abyss was a massacre of Childe's childhood. He grew up quickly mentally after the period of time he was in the Abyss, three months of being hunted by abyssal monsters and learning to survive. Soon, he was a Fatui, then one of the Fatui Messengers known as Tartaglia. Despite being a rude killer, he believes that children's innocence should be preserved and protected. Therefore, not long ago, he began practicing age regression in secret.

When he practices age regression, oddly enough, Childe is very sensitive. He cries easily and becomes very sad and scared if left alone. He loves drinking milk and stuffed animals, things that make him happier. However, he sucks his fingers a lot and is distressed about not having a pacifier.

Childe has red hair, pale skin, and dull blue eyes.
