HibariShikaru
Byakuran had always known from childhood that she was never meant to be normal.
She knew that somewhere out there in space existed alternate universes and galaxies,parallel worlds,and different planes of dimensions which hold different versions of herself.
She knew that she wasn't the only 𝐵𝑦𝑎𝑘𝑢𝑟𝑎𝑛 existing:there were many others like her,and all of them were also aware of her and the others' existence.
She knew the events or could see and even travel to those different world/universes in a spectral form and gain knowledge to improve her own world...after all,one world cannot have two 𝐵𝑦𝑎𝑘𝑢𝑟𝑎𝑛𝑠 or it might create a time and parallel world paradox and mess up the balance of the reality.
Byakuran knew that she wasn't the original-she knew that the original was male,in his mid-20's and was the Mare Sky as well as a close "brother" of Sawada Tsunayoshi...
Truly,it was a shame that her world doesn't have its own version of the Vongola 10th generation and Tsunayoshi--things would have been more fun if they existed.
Her world's balance was different,just like how other universes and parallel world differ from each other:there were worlds that had two to three crossovers of different "fandoms" and some that were more...original in their world system,per se.
Byakuran's world(her world,that is) however had a--surprise,surprise--a crossover of two...which was the infamous MCU and Harry Potter.
Hm,maybe everything wasn't as boring as she thought...
However,the annoying thing was that there would come a being that would interfere in her world's power balance as well as her universe:in short,she will have to find allies and borrow her original self's Tsunayoshi as this 𝑜𝑟𝑖𝑔𝑖𝑛𝑎𝑙 Tsunayoshi was the only one to defeat her original self.
Hah.Being a newbie in the line of work of a Mare Sky sure was hard-hopefully,she'd be able to subdue Thanos with Tsunayoshi and the others' help.
At least she won't
