TBT&TWT

While Three doesn't usually feel anything for humans, he is trusting of Black Suns, partly since they are both murderous evil spirits and they have ben together for quite some time. However, as evil spirits, Three is aware that someday, it may be the time when he gets betrayed by Black Suns.
While close, their friendship is also very closed, being an untrusting pair, their friendship revolves about fun rather than on emotional support. Neither want to show their weakest emotions to one another, but it's not like evil spirits have emotions anyway, riiiight?

Three and Black Suns both enjoy messing with mortals and one of their very own ways to do so is to force them to play killing games, where everyone gets to have fun or end up dead!

Sometimes one of them would act as the organizer, while the other acts as a victim, some other times, both would be the organizers and other times both of them would play as victims. They always have fun either way!
