She has also shown great concern about her appearance and weight, causing her to put herself on crash diets.

Tomoko Kawakami was a Japanese voice actress. Having graduated from the Toho Gakuen College of Drama and Music, she was affiliated with Production Baobab at the time of her death.

In August 2008, Kawakami was diagnosed with ovarian cancer, which required surgery. During a three-year battle with cancer, most of her ongoing roles were replaced by other voice actresses, although the latter was able to do some voice work until her retirement in the start of the 2010s decade. She died on June 9, 2011 at the age of 41.

The series is centered on 27-year-old homeroom teacher Mika Suzuki (who only looks about half her age) and the eccentric and colorful students of her class. <br><br>
