売ったれダイキチ！

Daikichi Sagano, a middle school student with dreams of becoming the greatest salesman in the world, lacks the know-how but makes up for it with enthusiasm. His life changes dramatically when he encounters Nekomister, an 800-year-old cat with a knack for business, who recognizes the potential in Daikichi's "Thousand-Ryo Eyes" to see what others desire. Together, they embark on entrepreneurial adventures, tackling local market challenges and school fundraisers, turning Daikichi into a budding merchant with each deal. As Daikichi grows under Nekomister's tutelage, he learns not only about commerce but also about friendship, responsibility, and the joy of helping others.
