~Helluva Boss : Sister Spotlight~
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!
