Isan Sozoku Bengoshi Kakizaki Shinichi

Kakizaki Shinichi is a lawyer specialized in inheritance law. Being riddled with debts, he often jumps at every opportunity to meddle with inheritance cases that he could makes some money from, accompanied in his quests by his greedy-but-lovely girlfriend Miki, by his even-greedier-but-oh-so-funny assistant Hana, and by Kawarai, the loan shark with a golden heart and a penchant for guns. The quirky quartet manages to solve all cases with huge doses of comedy and humaneness.
