A shitty dad through and through.
I wouldn't say that.
He was just more concerned for Hikari, because of her condition.
He scolded Yuriko from leaving her alone while knowing she was sick.
Which is still deserved.
As much as we know Yuriko was a kind and loving older sister, she still was wrong for just leaving her sick sister while no one else was around to watch over her.
You can't just say the dad was shitty, when he was just doing his job as a parent and scolding his eldest daughter for doing something so irresponsible.
Yuriko may have felt like she was ignored and not loved, but a parent won't just leave their sick child to someone if they don't trust them.
We have no information on if the dad was really bad or not.
But from what we were shown and told, it was Yuriko at fault.
She should have waited for his parent to arrive before asking permission to go out.
She should have stayed and held back her desire to leave in order to look after her weak sister.
And at the very least, she should have at least brought her sister with her (although this is not a very good idea)
The father still works hard for his family, Yuriko from her outfit still goes to school which shows his father still provides for her education.
Again, would a shitty parent put all this trust on her instead of just asking a friend to look after Hikari?
Yuriko was also a very quite and self kept girl, that's why her power became greed, because she used to hold back all her wishes.
Which means she never tried requesting anything or seeking attention from her parent.
Not every person is perceptive enough to be able to tell someone's emotions or desires.
If you don't speak them out they could possibly never know.
So her father might have thought Yuriko was a strong mature girl, who he could trust with Hikari.
And may have never known Yuriko was actually weak and wanted attention and validation.
Sure it may mean he didn't fully understand her, but that doesn't necessarily mean he ignored her.
They are both at fault.
Her father never asked, and Yuriko never said anything.
But that's normal for families, sadly enough, people can only guess and speculate unless told to them.
Her father was too busy with work, I wouldn't blame him if he couldn't find time to bond with them.
And Yuriko was too afraid too be a burden to her family that already had it hard.
Maybe in a different scenario, one where Hikari never got sick, maybe their father could have been less active in work, and spent more time with them.
Maybe we wouldn't have needed to earn so much for her medication.
And maybe they could have been a happier family, spending time together, all 3 of them.
