This here's story will be different! I had lots of ideas of what the next Helluva Boss story would be next, but I can't settle which I should do, so I decided to mix in 3 stories in one! This will probably be the longest I've made, and this is gonna be fun! ------------------ ~Blitzo and the others next assination for today is something different than usual, they all encounter not just one, but three cilents, who all have different tasks for them to kill, one who died from a kid's entertainment place, the other died from a bully at school, and the last who died from his Boss and her greedy instincts, so it's up to each of them to help them out on their problems and kill their targets, the adventure each have will be interesting~

~Helluva Boss : Sister Spotlight~ by Cyrilwolf

After years passed by, Blitzo gets a call from someone that he didn't think it would ever happened, a call from his older sister, Tilla, since tomorrow is her birthday, she wanted him to visit for her as a family reunion to have Blitz meet her own family, so Blitz, Moxxie, Millie and Loona go off to meet one of Blitz's sisters and learn that Tilla is now a rich and a famous girl in parts of the cities of Hell, they then meet her family inside, including her husband, who seems to not take a liking to Tilla's revealed brother and also supposedly Brother-in-law, he doesn't seem to trust him or his partners either, what he has planned for them will probably have to keep hidden for Tilla, to avoid any suspicious activity. -------------------------------- Yes i know Tilla was written off from the fandom, but it is once again my headcanon idea to make something in the fandom, to have Blitz meet up with his big sister after some time not seeing each other for so long, what better not to do that on her birthday!
