Easily pleased fan here. Didn't enjoy the ending too much, but I do like the idea of a parent bleach characters. So much so, I've been writing an entire series about them when their kids are in highschool in my head all day.
Couple fun bits I think people would enjoy in this possible fan fiction I might write.
Ichigo's kid grows up with a baby face and gets easily bullied. He has a very pushover attitude. Ichigo's parenting advice is "punch em in the face, stand up for yourself," but the kid takes after Orhime more a pushover and is kinda a moma's boy. Also easily frightened He tries to have girlfriends over, but everytime they do, they just fall for ichigo cause he's a hot dad. He's got a bit of a dad complex.
Ichiko(Rukia's kid) stays in the Kurosaki household to go to highschool cause Rukia had a fun time, so her kid will too. She goes to the shinigami realm on weekends and shit, knows everything about the human realm from Rukia dated information, and whenever anyone asks what her parents do "She's a captain" so people immediately think pirate. Also she has a crush on Ichigo cause hot dad. Basically more Rukia, cause let's be blunt, Rukia was hands down the best character in Bleach.
Ishida has a daughter with some girl he met in medical school. She's super smart but also has kinda a punk 'i'll fight you' attitude but is actually terrible in fights. She's also a terrible quincy. All her violent tendencies she got from her mother, and Ishida is always in a panic cause he doesn't know what to do.
Some weird plot points/head cannons for me.
Ichikia is actually Ichigo's daughter. They had a brief affair(Of which he told Orhime because Ichigo is the kind of person to own that, and Rukia doesn't tell Renji cause shit's hard. Ichigo doesn't know it's his kid though. Orhime suspects, which makes her staying there kinda awkward. Also Rukia is gently pushing her away from a crush on hot dad ichigo cause kinda awkward.
Ichigo's kid inherits the Almighty and seeing multiple futures at once is really too overwhelming to ever actually use.
At one point, to boost Ichika's sprits, Renji finds every eligible kid in his division and widdles them through various trials before they can go on a date with his daughter, making sure they're cute(but not too cute otherwise they might be womanizers) and strong(but not stronger than her otherwise she might get insecure)
Ishida's daughter asks Chad to teach her how to be a fullbringer so she can beat up a girl she doesn't like. He says he can't shes a quincy? "Why can't I be both?" "Well you gotta be attacked by a hollow." She then runs off to try and be attacked by a hollow and Chad has to chase after her.
I dunno, I would really like a manga where the characters are just trying to live in a post manga battle world as adults, with adult problems that go with that. Say what you will about Boruto, atleast Naruto is a shit dad and that in and of itself is really interesting.
