Yamabuki, Midori

Arale's beautiful teacher and Senbei's dream girl. After a long period of unrequited love and nervous misunderstandings, Senbei proposes to her while thinking she is out of earshot. Surprisingly, she accepts immediately (while on the toilet, no less) and they are married in the next manga panel, resulting in a name change. Despite Senbei not knowing how kids are made, she becomes pregnant and gives birth to Turbo. She is 23 years old at the beginning of the series.

Also known as: Midori Norimaki (則巻 みどり)
