Part of the Matsui x Shingo series.

Sae Aikyou is a 30-something woman, and an immense "sumo fan" who just can't get enough of professional sumo wrestling. Between touring the areas that are hotspots for sumo, attending official sumo tournaments, and watching the sumo wrestlers practice, you'll find Aikyou-san anywhere there's sumo wrestling! Because pushing is the foundation of sumo, sumo wrestlers wake up very early every morning so the can charge ahead in their persuit of proper pushing strength. So let's all chant "Dosukoi!" with Aikyou-san in this everyday comedy that's brimming with love for the sport of sumo wrestling! Source: Earth Star Entertainment
