Hagane no Tamashii presents: A very rare collection of music from anime Kurogane no LINEBARRELS. By conish (of later Yuugi Ou!-fame) and others. Not my rips but I searched quite long for these myself..

Someone seriously named "Kitei no Tsurugi" as "Keitai no Tsurugi" (Blade of Mobile Phone... man I laughed!) It's fixed here.

Also, excellent series!
