i will admit i'm not at all familiar with Kisumai, but i if they're similar to my favorite JE group ever, KAT-TUN, i should give them a try!!
but i have heard good things about them from the JE fanbase. also, i really want JE to debut a group or whatever who's average age isn't like...14 or something.
but there are rumors spreading around for a debut from these guys. i hope it's true!!
