Becoming the Reiwa Tea Sage in Tokyo

Lu Ya, an inept descendant of Lu Yu, the Tea Sage of the Tang Dynasty, is reborn as Sen Choyusai Ringa, an eighteen-year-old descendant of Sen no Rikyu, the Tea Sage of Japan, and heir to Tokyo's Mutaian teahouse. The teahouse is on the brink of bankruptcy.

Just before he's forced to sell it, he awakens a strange System.

This is the story of how he draws on the grandeur of the Han and Tang dynasties, takes on masters from every school, and step by step becomes the Tea Sage of the Reiwa era.

(No angst, no tragedy, full of passion and sweetness)
