This CD is part of the Limited Edition Joshiraku BD Vol.2. It has an alternate catalogue number, KIZB-90107, which is the companion catalogue number to the DVD releases.
First track, a character song, makes good use of Nozofis' cute voice. Second track, rakugo, has a surprising ending. I didn't find it all that interesting, but the KaneTomo imitation near the end is VERY impressive.
