eMu or DoM (ドM, read as de eMu) is a fairly new utaite who has just started from March 2016 with the first cover.
He has a soft, warm and calm voice which is mostly suitable for ballad, romantic melodies. It is noted that he can convey the song emotionnally with his beautiful vibrato. Those thing can be heard in his most popular cover "DAYBREAK FRONTLINE" which entered Hall of Fame (100k views) on January 25, 2017.
When nameing his covers, he always writes 【天性のドMが】 ... 【歌ってみた】 which means The instinct DoM tried to sing.
Along with uploading covers on NND, he also posts many short version covers on his Twitter and is active on TwitCasting.
