and then these three children grew up fucked up and codependent and murdered lots of people together, until they were finally captured and forced into prison at age 14
and they essentially dedicated their lives to him to the point that they willingly allow themselves to be possessed by him even when it horrifically damages their bodies
... Hakkai would treat him precisely the same, although, frankly, he'd probably feel much more kindly disposed towards Chikusa after that, because horribly abused, unhealthily dependent kid who rebelled and murdered a bunch of people is the sort of backstory that makes him feel much more positively towards somebody
Ken, the kid who that is happening to, has an ability where he can insert different "cartridges" (aka fangs) into his mouth, and he gains abilities based off of the animal it belongs to
He's the son of a prostitute, but she abandoned him at an early age and didn't even give him a name. He was either born with or lost his right arm completely, so... yeah
Him and a group of six other kids basically made their own family on the streets of the super bad East End, but didn't have a home or any way to reliably make money, and were basically slowly starving to death
...until a nobleman found their group and took them to an orphanage/workhouse where a bunch of other orphans lived. There were green fields, and gardens, and everything was great! :'D
Joker and his particular 'family' were taken into the nobleman's service for working in a manor, and Joker in particular got the "honor" of being his butler... as the nobleman started getting in deep
Joker was forced to do a lot of unsavory shit (like murder), and had no way of refusing or else his family and also all the other kids at the workhouse would be fucked
His family is forced to go around England under the guise of a traveling circus while kidnapping kids all to find the one kid that the Baron is SUPER obsessed over
I'm pretty sure I've seen at least one headcanon where that eye had passed through the bodies of other people and that's where Mukuro gets his Paths bullshit from
my headcanon past fic thingy basically hibari's father had colluded with a weapons dealer who were like 'lol lets try this shit out on a person' and thats what happened
but yeah this is what Chikusa and Ken let happen to them, perfectly willingly
hey look in my headcanon past theres a group who deals with human weapons and got involved in this shit okay but i didnt fully flesh it outI'm pretty sure I've seen at least one headcanon where that eye had passed through the bodies of other people and that's where Mukuro gets his Paths bullshit fromthat makes a lot of sense actually
