Dan Heng

A character in Honkai Star Rail who is the resigned babysitter of March 7th and the Trailblazer. Not-so-secretly a dragon, just like Neuvillette and Zhongli in Genshin Impact. His dragon title, "Imbibitor Lunae," roughly translates to, "To Drink the Moon," just like Chinese folklore for dragons.
He's an introverted individual who has occasional sarcasm, particularly with March 7th. He's quietly kind to all, but he does get irritated when people only see him as his past life, Dan Feng.

Dan Heng's such a sweet guy. He fits the deuteragonist stereotype, but his writing is impressively fleshed out.
