all the people here didn't get that the quints don't wanna talk to the dude because he left her mother before they were even born?
man, if that old guy comes one day saying he's my father an saying such nonsense about my mother I would tell him to fuck off and go on with my life, more the like when Maruo, althought not a caring father figure, has been more than enough for them since her mother died.
He's totally a bad character, is 2 dimensional, and is obviously a device plot for itsuki, but I can totally get the quint's stance in this 3 chapters as something possible.
Is not something Negi properly show to us, but her father was never dead or missing, is a shock for us readers because it was never explained, but I know a lot of people who comes to meet their biological father and go "meh" because it was never there, more the like if they come all high and mighty about knowing better than them about their life
