Shu's children

This is a 10+ year time skip.

Shu and Shinso got married relatively early at 21 after a 5 year relationship. Sayaka at 23, the twins at 24 and Saeko at 25. Ryota and Ryoba don't count, as they were adopted when Shu turned 21 since her grandparents ed away. Shu is only having these 6 children, as it appeased the chairmen and people of her clan AND the HPSC.

As you can tell, Shinso's genes fought tooth and nail. Especially in Sayaka and the twins. This is primarily because Shu is an albino. Sayaka has Shinso's hair but Ryoben's eyes and skin (Shu's biological father). The twins have Shinso's hair color but in a darker shade like Shu's mother's, but Shinso's eyes and skin. Saeko has (whom I headcanon) Shinso's grandfather's hair and Shu's eyes and fair skin but not pale.

Ryota and Ryoba inherited subversions of their biological mother's quirk (Wagamama=poltergeist). Sayaka can create illusions from mist (which I'm not sure who leads that in of genetics. Likely Shu). Shoichiro can control dolls while Shousuke can control people's bodies (Coming from Shinso's brainwash quirk.) And Saeko is a mermaid, (which is definitely from Shu.)

Technically Ryota, as the oldest, and male, would become the fated master of the clan and take Shu's place. However, Shu is training Sayaka instead. Likely because Ryota isn't Shu's biological child, instead Wagamama's who is long ed. And Shu is the last living heiress.

Shu does everything in her power to keep the HPSC and hero affairs away from her children and marriage. For fear of one crossing over the other and somebody getting hurt, or her children becoming a target for villains, or her husband having a harder time with work. Keeping a fine line between work and home. Choosing home over work. And doing whatever she can to make life easy for her kids and husband.

Surprisingly, after Saeko, Shu became a stay at home mom. Sorta. She took up an offer to work from home to be around her kids while Shinso went out and worked. But not to be mistaken Shu as a housewife. She still holds high power and position in the HPSC as vice president and ambassador. She just does paper work at home now where she can keep her eyes on her kids.

Shu has a relatively calm life, stay at home worker, happy husband who was her high school sweetheart, 6 kids, 2 seniors. Shu's been doing well.
