This CD+DVD package contains the fourth single by Nonaka Ai (野中藍).
The tracks are as follows.
Happy Material is a cover of the Mahou-sensei Negima OP.
The DVD contains a promo video of Cheer Ruga. EXTREMELY cute video! This is one of my favorite PVs of all time.
This CD comes with a ticket to send in for Nonaka Ai's "Triple Release" events in December 2007 (Osaka 12/8, Nagoya 12/9, Tokyo 12/16).
Unfortunately, I didn't get a ticket to the Tokyo event.. (;_;)
