Shinobu Takeuchi (Mikako Tabe) becomes a homeroom teacher at Ooki Elementary School in Osaka, Japan. Shinobu loves mystery novels and can't stand things when it doesn't turn out right. Shinobu then attempts to solve a difficult cases that even detectives can't solve.
This was a hilarious detective story that Mikako showed us beside "Deka Wanko". I just realized Fumino and cuite Minami also were there 😁. .
The bickering between Koike and Mikako was one of the show. It's simple story to follow. Mikako wanted to get her licence buy always got trouble while the called real detective Koike always got trouble by her and her persistent to be like detective.
Not only the two of them but also the students got involved.
Such a nice detective story with comedy in it. Well of course too much trouble in it too. That was because the main character was too naughty. Each episodes had it own cuteness and clumsiness. I couldn't reject the deduction Mikako gave us.
