When a girl gets kissed she gets with child...

Shigezane definitely wants -- and has -- a big brood of children

He is so, so, so thankful to MC for making this wild dream of his come true

He gives each of their newborns a smile so broad MC thinks he might burst

Her heart melts when she hears Shigezane softly singing a lullaby to their infant

He's the non-toxic sports dad -- he'll play every game with his children and encourage them to get out and get active, as long as they play fair

Honestly, Shigezane loves playing with his kids no matter what they're up to and doesn't have to be coerced-- MC has caught him making bracelets and holding faux tea ceremonies with them on more than one occasion

Everything they make is a masterpiece as far as he's concerned

He's also big on piggyback rides, the tickle monster, and carrying kids around in general. Has lost many a fake swordfight.

He likes taking his family on outings to see fireworks or join Tsunamoto on trips

He loves spoiling his kids and MC has to reign him in a bit

He is, therefore, the Cool Dad (TM) to his children's friends

Having said that: talking back to him? Bad. Talking back to MC? Absolutely unacceptable. Go muck out the stalls until you've learned some respect.

Under all that goofiness he is very, very, very astute about his kids' emotional state -- he's memorized his children's every gesture and expression over the years. There is no fooling this man. If a kid of his is sad, or scared, or angry, he knows it.

He won't force his kids' troubles out of them, but he wants them to come to him and he wants them to know that he wants that

Absolute master of the pep talk

He's a fairly relaxed parent compared to Kojuro or Masamune without being neglectful or overly permissive -- he thinks it's healthy for his kids to learn from minor scrapes

However, he will give his kids a heart-to-heart if he thinks they're about to do something unethical or injudicious or that will otherwise make them unhappy long term

He makes it clear that no matter how old they get they can always, always, always come home to Omori

He is very eager to teach his kids how to ride and starts teaching them a little younger than MC would have approved of, resulting in a minor argument that is resolved by her agreeing to join in if he does things on her terms

Shigezane actually cools it on the number and duration of visits to Yonezawa until his kids are up some age. He doesn't want to leave MC at home with a young child or one on the way, and he doesn't want to exhaust or endanger any of his kids on the road.
