Choshinsei is releasing 3 new singles, All About You, J.P. -Reborn- and Magokoro. Each single will have three versions, a Regular Edition, a Limited Edition with DVD and a Limited Edition with postcard. There also seems to be some kind of promotion where if you buy three of the singles you get to go to a special event. It doesn't really specify on CDJapan though.
Magokoro will be released on May 12th, All About U will be released on May 13th, and J.P. -Reborn- will be released on May 14h.
