From MangaHelpers:
Okitegami Kyouko is a famous detective who solves cases in a single day. In fact, she has to, since her memories only last for one day before they 'reset.' However, for important things, she writes messages for herself down on her body with a special pen. One of her common clients is Kakushidate Yakusuke, a man who is often wrongly suspected of committing crimes. There is also a live-action drama adaptation of this story.

Kurokami Medaka, a first year, is elected as Student Council President, and the first thing she does is establish a suggestion box. Since she was just elected as Student Council President, she's holding all the Student Council's responsibilities, and wearing their armbands. So she asks for her childhood friend, Hitoyoshi Zenkichi, for help.
After filtering through the suggestions, which were mostly ridiculous complaints or congratulations on becoming president, they find out the Judo Club needs one more member to participate. So, Medaka volunteers her and Zenkichi, who have both been practicing Judo for years, to help train the club and borrow Zenkichi for the match.
