【Ren】 (【蓮】) is an utaite who mainly covers VOCALOID songs, but sometimes also covers songs of other groups or singers like GReeeeN or KOH.
He has an extraordinary vocal range and the ability to sing in both high and low tones, fitting any genre well. He can sing heavy and dark songs like in his cover of "Leia" or light and quiet ones like in his cover of "Nee." .
His most popular single cover is "World's End・Dancehall" with over 1.2 million views and around 33K Mylists on as of October 2013.
He often collaborates with Dasoku and they released a CD called "1122".
At the end of May 2011, Mari-san, 【Ren】's girlfriend, had died in an accident. Eight days after the accident, he wrote on his Nico Nico Douga Community about her death and the torments she had endured from a fraction of his fans. But even though she was harassed, it didn't shake their relationship and Mari-san continued to support and encourage 【Ren】 to keep on singing. “No matter what happens, please don’t give up singing.”
In honor of Mari-san, 【Ren】 sang "Namae no Nai Uta", which can only be viewed in his community.
He often calls himself an "ossan", which is slang for a "old man".
Despite retiring from Nico Nico Douga on March 8 2017 , he still collaborates infrequently with Dasoku as DSK x REN, with uploads made on Dasoku's channel. In addition, he is slated to perform live at Chang Gero Sonic 2019, although it is unknown whether his return will be permanent.
