Approximately 20 years ago, Deejay, NATURAL WEAPON, and ARARE, who are the same age, suddenly burst onto the scene and quickly made a name for themselves all over the country with their outstanding sense and ability that belied the fact that they were teenagers.

The positive messages the two of them speak to each other as kindly as if they were speaking to a young child, gently warms the heart like a pocket warmer.
