Quick translation I've done.

They are Babymetal. They're 3 little wild girls from Japan, who became a worldwide musical phenomenon.

Jaunty pigtails, lolita miniskirts and an unexpected heavy metal soul. They don't make 50 years in three, Su, Yui and Moa (Hello! We are Babymetal).

A little bit manga, a little bit dark. They are Babymetal, the japanese band that after conquering the east they became a truly worldwide phenomenon.

10 singles on top of the charts, MVs with millions of views on the web and millions of fans all around the world. These are the record numbers of these little stars that look like they came out from a cartoon (sic!). But it is known that appearances can be deceiving, and when they take the stage the real show begins.

Skulls playing the drums, rigorously gothic scenography and a completely original musical genre. A mix between Japanese pop and idol that they call "Kawaii metal", metal that's not heavy but cute and makes people dance in venues and even whole stadiums. And during the word tour the wonders' trio stopped in Italy as well, in Bologna, with a sold out concert at the neat pop festival [not sure what they meant here, I've never heard of such festival in Bologna, and Babymetal date wasn't part of any festival or open air].

The Fox God, the god of the heavy metal, personally appointed them. Bringing back this now lost music it's the mission of the trio, explains their visionary producer, while the critic say this is a marketing operation really well done.

In the mean time Babymetal fans are multiplying, from the States to the Europe. An unrestrainable success, until the next hit.
