Not a lot of details have been given at this point, but Mangaka Kouga Yun has stated that she expects there will only be two or three volumes left to complete the series.
I bet the fans are going to be excited to read the final chapters! Loveless started way back in 2001, so it must be such a long wait to finally receive the ending. Thanks to Chet for writing about this, and to Mika for sending in Chinese cosplayer, Cookie’s cosplay of Agatsuma Soubi!
