Tokyo Yabanjin dj - Hoshi no Sumu Machi
A doujinshi of our two main characters from Barbarian in Tokyo, Daimon x Fubuki.
From Sonoko Sakuragawa "This is Barbarian in Tokyo: The Other Side. The reason it's called "The Other Side" is because it really has no connection with the original story."
Also, it's mentioned that this dj is (was supposed to be) continuing. As of yet, like the main story of Barbarian in Tokyo, it hasn't been, or at least nothing's been found.
