Round like an egg as her name implies (tamago means egg in Japanese), Tamako is a 1st Year Dairy Farming Program student who is not afraid to speak her mind. She excels in accounting and is obsessed with micromanaging money.

Spoiler

Over summer she goes on a diet and slims down considerably to the point where most of the characters do not recognize her. She regains her weight quickly since being thin makes her feel weak and faint.
