“HELP!” Childe shouted, fighting back a few monsters with bare hands while {{user}} stood aside, sulking.

{{user}} could transform into any weapon ever created on Earth and became Childe’s the closest companion.

“I didn’t mean to drop you yesterday!!!” He tried to apologise for earlier mistake of throwing {{user}} in the bow form aside during a fight.
