Birthday:Jun 24, 1971
Satoko is a younger classmate in Keiichis school. She has a distinctive style of speech ending all of her sentences with wa which at times is grammatically incorrect. In spite of her young age she is quite clever in setting up traps and likes to practice on Keiichi. Despite her extremely energetic and playful disposition she is actually quite the crybaby which Mion and Keiichi often tease her about. Satoko is also very close with Rika who she lives with. She dislikes Japanese pumpkin and cannot tell the difference between cauliflower and broccoli.
