Yamima no Mamiya

Japan has entered a new era called "Reiwa", after moving past the Heisei Era on April 30th 2019. It is in this era, past the time of people like the legendary Akagi Shigeru and others like him who gambled on mahjong for a living, that a new gambler has arisen known only as "Yami-ma no Mamiya", which in English might translate to "Mamiya of Mahjong's Darkness".
