Hell is a chaotic place-Demons battling for territory, excessive temperature, and overpopulation, coupled with a yearly purge to lower said population.
In this place of misery and despair, it would be inconceivable that a pure heart could exist. But indeed there was one in Charlotte Magne, or as she is known by friends, "Charlie." The young princess was rather naïve, but she believed that deep down, everyone held a small shimmer of light that could hopefully be brought out. Charlie was quite invested in the wellbeing of the denizens of Hell, despite the fact that a good majority of them were violent, indifferent, or downright hateful and evil.
She saw the angel's extermination as inhumane, and downright cruel. While the sinners had already died, their weapons could destroy their souls, and extinguish even their spiritual life. So in the hopes of redeeming them, she opened the Happy Hotel, a place she believed could make a difference, and maybe see a few souls off to Heaven and end the "cleansing."
So far their only client was an effeminate spider demon named Angel Dust, who actually had little to no interest in redemption, really only milking the Hotel for free habitation.
So far, nothing compared to what a young saiyan went through. Several years after killing Future Dabura and Future Babidi, and nine years after the fall of the Future Cell, Now Age 796 an enigmatic man named Black goes berserk and causes humanity to be on the brink of extinction. Trunks attempts to stop Black, but fails. Bulma suggests that they should receive help from Goku and Vegeta in the past. Six months later, Bulma gathers enough fuel for a one-way trip to the past for the Time Machine, when all of a sudden, Black gets in their way. Future Trunks shields his mother when Black destroys the lab. Future Trunks is shocked to see that Black has Future Bulma. Future Bulma then tells him to go on without her, and that getting back to the past is the highest priority. Black then fires another ki blast, destroying the lab and Future Bulma, much to his horror. He then shakes it off and runs to find Future Mai, knowing that getting back to the past is their highest priority.
Future Trunks manages to escape from Black and get the time machine 16 years into the past traveling from Age 796 to Age 780, where his time machine is found by a woman and he is located unconscious inside by his present counterpart. He is then rushed onto a gurney, where Trunks gets to see him, and is shocked by Future Trunks' arrival. He is then with Bulma, Vegeta, Goku, and Trunks, where they see him in his current state, much to their corresponding concern. Trunks eventually wakes up. Upon seeing Goku, Future Trunks begins suffering from PTSD and mistakes Goku for Black. Future Trunks suddenly rushes out of his bed and attempts to attack Goku in anger, much to Goku's confusion.
"Where am I?" I can't sense Zamasu… What's going on?!" Trunks asks himself as he gets himself up. He then sniffs the air. It's… surprisingly not different then he is used to. Meaning, he thought he was in the future until he saw the landscape. Yup. No capsule corp buildings in sight, and no Black or Zamasu. Where was he? He then felt something sharp press his throat. Trunks looks behind him to see a hellhound pressing his knife against Trunks neck. Trunks rolls his eyes as normal things like knives do jack squat to him.
"Let me guess, you want my money." Trunks said with a tired tone. Truth be told, in his coat he had twenty bucks. But that was until Black showed up…
"No shit! Now hand it over!" He then sees Trunks' sword "And the sword! I don't have all day!" Trunks sighed and grabbed the knife and crumpled it.
"Look, if you haven't figured it out, but I have more things to worry about. So tell me where I am please." Trunks is NOT in the mood. After killing zamasu (or destroying his physical being), he is left tired, worn out, and most of all, emotionally scarred. The hellhound growls and tries to scratch him. He grabs the hellhound's arm and snaps it in half. The hellhound screams, attracting another canine's attention, impressive in it's own right because her face was glued to her phone half the time. She peeks and sees Trunks.
"I would say welcome to hell, but," He looked at her confused "I think you already figured out." She said.
