This page is about the duet unit between Dasoku and 【Ren】, also known as Dasoren , DSKxREN, or simply 1122. They often collaborated with each other from 2010, although 【Ren】 stopped uploading songs after 2014. They released one album together named "1122".
Despite 【Ren】's retirement, the duo still collaborate infrequently, with uploads made on Dasoku's channel.
Their original unit name was 1089, the square of 33, as both of them were 33 years old at the time. However, on【Ren】's 34th birthday, they uploaded Yogoreta Prism" and announced that their unit name from then on would be 1122 (33*34). 
1122 is a Japanese pun for "いい夫婦 ii fuufu" ("Good Husband and Wife") and November 22 is known as Good Couple Day in Japan. Dasoku and 【Ren】 often upload on November 22 to commemorate the occasion.
