As a spirit medium, Seiko's duty is to eliminate the evilness of the yokai spirits swarming around the Kamigoe City. Not only that, she also helps her grand-daughter, Momo, her friend, Okorun too, and recently a new member onto the friend group, Aira...or, if she even gets along with Momo of course. However, with Okorun, she gets along with "very" much, making Momo very jealous about it. With that said, she then looks after her grand-daughter, and her friends as she invites them to their home any time, any day, free meals, and doesn't mind staying over as well. Despite Seiko having such uncouth manner of speech, deep down her heart, she's selfless and empathetic towards others in need it's within her power. On top of that, after helping others in need and accepting them, she awards them by letting them stay over, feed them, and helping them in any occasion. And now, she soon awaits a visitor to help in need, but before the help arrives...she then encounters someone who is possessed, but not a yokai...but, an unimaginable, and a way urban legend than Turbo Granny.
