Jin Kobayashi 小林尽 is a mangaka. His most famous work so far is School Rumble, He began drawing manga seriously during his college years, and won the Weekly Shonen Magazine's Rookie Award in 2001.
Another good entry. One enjoyable feature of this series is that they keep mixing things up; some time is spent on one set of characters and then another story-line is explored. All are enjoyable.
I also appreciate the translation notes at the end; they help me to learn Japan's culture.
