Thank you, I'm glad you liked it! Lol Isshin is very much the outsider to his own family after Ichigo neutralized him, they're basically like two strangers who happen to live in the same house, and even then, Ichigo went and got his own apartment once he had the contacts for it. I wouldn't say he set out to alienate his sisters from Isshin, so long as Isshin wasn't hitting them too, he doesn't really care what their relationship is like, but considering Ichigo's also been pretty much raising them single-handedly for the past 6+ years, they're bound to learn from him when it comes to Isshin too. Plus they do remember the way Isshin used to smack Ichigo around before Ichigo put a stop to it. So anyway, the twins still talk to Isshin and let him be his loud dramatic self around them but there isn't really any love coming from their end when it comes down to it, and they live with their brother at the apartment half the time anyway. As for Ichigo, he actually doesn't hate Isshin or anything either after the man left him to his own devices and doesn't bother him anymore. And yeah, the fact that he's the nominal adult of the house is still useful since Ichigo's still underage. It's just that he also very much wouldn't care if Isshin kicked the bucket tomorrow.
The Urahara/Ichigo/Shinji is also a surprise to me lol. Tbh, I didn't really have a ship in mind when I first started this AU, but UraIchi is my otp so naturally if there is a ship, I'd go for that. But then I wrote Shinji, and suddenly ShinIchi became a lot more probable, and then I wrote the Yuzu POV and Urahara elbowed his way back into the race. So the most likely ship now would be UraIchiShin lol.
The UraIchi dynamic actually turned out pretty interesting in this 'verse cuz this Ichigo is the type to get rid of anything that irritates him. If it's annoying and cuts into his time, he's not the sort to put up with it. And yeah, Kisuke's strong enough with enough connections that if Ichigo wanted to off him or even just threaten him like he did Isshin, it would be really difficult at the moment, but at the very least, he'd still work towards it, and he wouldn't spend any time with the guy. But here he is inviting him over for dinner and letting him properly meet the twins and just generally tolerating his presence, something he's never done with anyone else before, and it's a toss-up whether he's even really aware of the exception he's making. And on Kisuke's part, he doesn't know Ichigo well enough yet to realize how much leeway Ichigo's given him.
This Ichigo is just Grudgingly Fascinatedᵀᴹ by this cryptic bastard making his life a lot more complicated than he'd like, but is also strong and smart and offered his life up on a platter the moment Ichigo asked for it like it's tradeable currency so whatever he wants Ichigo to do in exchange has to be something even Urahara can't do himself, and Ichigo has just enough curiosity for that to add to the fascination pile just as much as it adds to the annoying asshole pile. Meanwhile, Shinji's just chilling with his poison rice, and Sakanade thinks Ichigo is yum with an adorable kitten for a sister. TLDR they're a trainwreck in the making but a pretty entertaining one.
I'm not sure what I really want to do with Mizuiro here yet but I'm definitely giving him a powerup in the future, he's Ichigo's best friend here, as much as Ichigo or even Mizuiro can have friends, and Mizuiro is absolutely ride or die enough to invade Soul Society with him. Plus I'd like to see what I can do with a character who's not exactly a frontline fighter but not a healer either like Ichigo's canon friends.
