In addition to their new costumes, as shown above, the band is also embarking on a fairly extensive free one-man tour. From the bits and pieces I could understand from their article on Visunavi, it seemed like they were disappointed that some fans couldn't afford to see them all the time, so making their shows free is an effort to reach out to others who might not have been able to see them otherwise. I guess Yuuga's getting soft in his old age ;)
Full details about their tour, as well as an interview with the band can be read in native Japanese here.
