Daniel's a personal demon to gun, no I don't mean personal demon as in those bad thoughts telling you to act on your homicidal ideation, or a repressed trauma memory or whatever,
Daniel being a personal demon to gun means whenever gun needs help or gun calls out to him, Daniel will immediately be by his side. Willing to do whatever gun asks.
If gun is dealing with mental issues that he will never admit to absolutely anyone, Daniel will take action and try to talk.
And if gun needs a relief from stress or someone to dispose of..Daniel will be there to help.
Easier way of putting it, Daniel willingly works and helps gun without asking for anything in return, it seems.
Oh, And Daniel IS an actual demon.
