Bleach Plot Bunnies for Adoption

The Hokioku abandoned Aizen when he was defeated by Ichigo Kurosaki. Causing the substitute’s shinigami powers to be temporarily sealed away in order to recover.This left his Hollow side to be left in full control.
Due to a combination of Ichigo's unstable reiatsu and the Hogyoku, the feral Vasto Lordre is transported to the land of Fiore.
After wandering for some time he comes across a small and very scared girl crying in the middle of a forest. The instinct driven being considers simply eating her. But he sees her crying face and something deep within his soul screams agents it. His instincts scream to ‘protect’ and so he does. Making sure she’s safe and fed. Wendy, as he learns the girl is called, eventually starts to think of and call him her big brother. For lack of any other name to call him by. Refusing to continue calling him “ Mr. Monster ''. And though he is a creature of pure instinct, it feels strangely familiar to hear someone call him brother.
Years go by like this. Ichigo protecting the territory he’s claimed as theirs. As well as helping to teach Wendy how to fight and survive to the best of his abilities. The best that a feral Vasto Lordre who can only communicate in demonic sounds can. A talking cat that Wendy names Carla joins the makeshift family a year later.
Ichigo grows to see both of them as his sisters. A term he doesn’t remember hearing before but seems to remember and instinctively know the meaning of. Carla comes to see both Wendy and Ichigo as family.
As an attempt to repay their brother for taking them in. Both Wendy and Carla take it upon themselves to teach Ichigo to speak. And though their efforts yield very few results. Ichigo is able to say a handful of simple words. His first words being their names. But even if he miss pronounces most words and they sound like they’ve come from the deepest pits of hell. It’s still an improvement. His voice stopped scarring them so long ago they don’t remember a time where his double toned voice didn’t put them at ease anyway. They continue like this for several years.
That is until their lives are interrupted by the Oracion Seis and the awakening of Nirvana. Wendy,Carla, and Ichigo are all separated in the chaos. Luckily, Wendy and Carla are found by the guild wizards instead of the dark guild. And though they are both terrified, this being their first interaction with humans. They eventually become friends.
Nirvana and the Oracion Seis are defeated much quicker and easier. Both As a result of a pissed off Vasto Lordre, an exceed and a more confident, strong and slightly feral herself then she was in the canon Wendy.
The meating between Ichigo and the guild wizards does not go well. The Guild Wizards believe that Ichigo is either another dark wizard or one of Zeref's demons. Going as far as to try and keep both Wendy and Carla away from him. Almost causing him to kill each and every one of them. And Ichigo seeing them as intruders(which they are) and a threat to his little sisters.
It’s only due to Wendy and Carlas negotiations and the fact that Ichigo's soul reaper powers are almost fully recovered( though not enough to awaken and regain his human consciousness) that they are able to avoid the bloodbath.
The wizards of Fairy Tail ask Wendy and Carla to join their guild. Meating and befriending others of her kind has made Wendy curious about what civilization is like. It takes a bit of convincing. But Ichigo eventually agrees to let her join on the condition that he does as well. The wizards begrudgingly accept. All except for Gray.
And so the makeshift family of an Exseed, a Dragon Slayer and a wayward Vasto Lordre join the Fairy Tail guild. Of course Ichigo already has a reputation. Being a SS-Class monster with countless kills to his name. The guild is rightfully a little more than on edge and borderline hostile.
When Grays had enough of the Hollows presence he confronts him in the middle of the guild. Yelling about how he’s a monster and how he killed all those people. Which Ichigo replies with a simple “ Trespassers” and “ Must protect”. His voice sends chills down the spines of all but the most seasoned members of the guild. To which Gray demands what is so important that he killed countless. Ichigo wordlessly looks at Wendy and Carla.
The only reason he doesn’t just kill Gray is that his soul reaper powers are starting to awaken. Giving him far more control than he’s had in a long time. It’s only a little bit later while walking up to the guild hall that his powers reawaken. But being in that form isn’t without its consequences. Waking up at Porlyusica’s cabin as an Arancar. Though he still doesn’t have the memories from his life as a shinigami, he remembers everything as a Vasto Lordre.
