Shizuka-chan (静香ちゃん) is a smart, kind, and pretty neighborhood girl. She is just unlike Nobita: being quick and very good at studying. Shizuka takes baths several times a day due to it being her passion.
Shizuka is very kind. She cares for weaker people and neglected dolls. She wishes to be a nurse, or an airhostess when she grows up. The jobs all reflect her kind nature.
She is also known for taking piano lessons so she can refuse to hang out with Nobita. Her true passions are sweet potatoes and the violin, in which her playing is as atrocious as Gian's singing.
Shizuka has a split personality. There are scenes that show her sleeping and eating at the same time, stealing her mom's lipstick for her to play with, and slipping over a banana peel.
Shizuka's mother is a kind woman. Shizuka's father appeared in only a few episodes, so not much is known about him.Shizuka's mother is shown in a few episodes telling Shizuka to have a bath or eat or go to her piano lessons.
Nobita - She loves Nobita more than any of her friends, but she gets angry when he looks at her bathing. She will marry him in the future, and their child's name will be Nobisuke Nobi.
Gian - Shizuka and Gian are friends, but Shizuka gets worried when Gian invites her to his music concerts along with her other friends.
Suneo - Suneo and Shizuka are very good friends. He invites Shizuka, Nobita, Gian, and sometimes Doraemon to his house and tries to ask them to come with him at trip (in which Nobita rarely gets a chance to come with them).
Doraemon - Shizuka often invites Doraemon and Nobita to taste the cakes and cookies she made, which taste very good. Sometimes she ask Doraemon to borrow his gadgets, which he happily agrees to do so.
