Sumiko Kobayashi

Sumiko Kobayashi (小林 澄子), the Teitan Elementary School Homeroom Teacher of Class 1-B and the romantic interest of Ninzaburo Shiratori, is a recurring character in the manga and anime franchise Detective Conan.

Background
Sumiko Kobayashi attended Teitan Elementary and was in the 18th graduating class, two classes above Kazunobu Chiba. She became the new class teacher of Conan and the Detective Boys after Toya, their previous teacher, had married and retired. Her harsh behavior towards her charges had earned her the nickname "oni-baba" (hag) amongst her students.

Personality
Sumiko is very kind and fond of children, considering them the most wonderful thing in the world. Sumiko is also quite timid and sensitive, not to mention that she suffers from serious stagefright. Even though she has appointed herself the manager of the Detective Boys, the kids often leave her out of case or ignore her warnings. She was also quite hurt when she believed Inspector Shiratori was only interested in her because of her resemblance to Miwako Sato, a resemblance so striking it even fooled Sato's close associates Chiba and Yumi.
