Seiko Yoshida

Seiko Yoshida is 161 cm tall.

She has long black hair, usually tied in a single ponytail.

Her signature outfit is a white apron, giving her the "traditional mom" vibe.

Even though her age is unknown, she looks very young and lively.

She says that after becoming part of the "clan of darkness," she stopped aging.

Seiko is a strong, kind, and playful mother.

She always tries to stay positive, even when money is tight.

She’s thrifty and great at saving money, making sure her family has what they need.

She loves to make jokes and has a cheerful spirit.

Seiko is also clumsy sometimes, which is where Yuko gets her own clumsy side.

She is forgiving and doesn’t sweat the small stuff.

She can be a bit careless, like using their demon ancestor statue as a doorstop or meat tenderizer.

Seiko is the wife of Joshua and mother of Yuko and Ryoko Yoshida.

After Joshua went missing, a curse placed on her family by the Light Clan took away their power and luck.

She is in charge of raising her daughters on her own with a tiny monthly budget (only 40,000 yen, not counting medical and school costs).

She hid the truth about Joshua’s identity and the family’s situation from her daughters at first, especially from the weak Yuko.

Seiko does not age after joining the clan of darkness.

She is skilled in using cheap ingredients to make tasty meals.

She is very good at finding the best deals at supermarkets and using time sales to save money.

She is very close to her daughters, Yuko and Ryoko.

They call her “Mom.”

She cares about her family a lot and always tries to keep them happy.

She sometimes jokes around with Lilith and even plays little tricks to keep her quiet.

Seiko used to enjoy entering contests and collecting stamps, but she never won anything—possibly because of the curse.

She loves using point cards from the Tamazakura Shopping Street and saved up for nice dishes.

She can make beautiful art from flyers, such as folding them into a phoenix sculpture or little trash boxes.

She does a happy dance when something nice happens, like winning new plates or getting a new fridge.

Managing Family on a Tight Budget

After Joshua disappeared and the curse hit, Seiko had to run the family with very little money.

She became an expert at saving and using food wisely.

She taught Yuko how to help with cooking and used tricks to make meals bigger, like adding tofu or okara to pancakes and okonomiyaki.

Secrets and the Truth About the Family

Seiko kept the truth about Joshua’s past and what happened to their family hidden from her daughters.

She didn’t want Yuko to worry, since her daughter was sickly.

When Yuko awakens as a demon girl and grows horns and a tail, Seiko finally tells her everything about their family’s story.

Fun and Silly Moments

Seiko has many funny scenes, like forgetting to measure the door when buying a fridge, so it couldn’t fit in their apartment.

She sometimes puts the family’s ancestor statue in silly places or uses it for odd jobs around the house.

She even offered Lilith drinks to keep her quiet when she tried to act like the family boss.

During a welcome party, she wanted to mix up boxes containing Joshua’s remains for a silly quiz, though this idea was stopped in time.

Dealing with Others

Seiko welcomes new neighbors like Momo Chiyoda and Mikan Hinatsuki warmly.

She even asked for rice vouchers as a greeting gift.

When Momo brought beef as a gift, she made everyone stop and admire the beef before making sukiyaki, since it was such a rare treat.

Staying Playful

Even after the curse is broken and there’s more money, Seiko keeps shopping for cheap food and never wants to spend too much.

She keeps a light and cozy feeling at home, making the most out of small things with her family.

Seiko is famous for her flyer art—she can fold flyers into birds, boxes, or even paper gun toys.

Yuko learned how to make these small boxes from her.

She and Lilith sometimes share drinks, and when she’s had a little to drink, Seiko gets even more silly and fun.
