Also known as: 西寺郷太, 月曜先輩
Japanese musician, music producer and the vocal of rock band Nona Reeves.
(Unfortunately) associated with the Inmu and Cookie fandom for his resemblance to Yajuu Senpai, and certain shots from the band's MVs has been parodied, most famously LOVE TOGETHER, ENJOYEE! (YOUR LIFETIME) and this hilariously bad live concert featuring a disastrous guest appearance from You The Rock. Routinely appears in Inmu parodies in the form of Spinning Yajuu Senpai, a spinning record with his face on it. He used to be pretty upset about being associated with Inmu, but gradually came to an acceptance.
Also known as the Monday Senior, because he emcees for a certain informational program every Monday.
