Mad Hatters

The Mad Hatters is a local four-person rock group that was called to perform at the Marukane Department Store Live Event.

History
At some point, the four young men formed a rock band, which they named the "Mad Hatters." They have been noted to be skilled musicians, but it's unknown if they've ever performed at a concert as big as the Narufest.
