Just last week it was revealed that ex-Shounenki vocalist, Kou (now known as Sera), had started a new band with fellow ex-Shounenki member Eiki (now known as China), called Hakujitsu no Yume. However, just a week later, vocalist Sera has announced the start of yet another band, and with another ex-Shounenki member as well! Just like Hakujitsu no Yume, this new band also has a rare and peculiar name for a band: Kurohime no Muyuubyou (黒姫の夢遊病). This band included, as previously mentioned, another ex-Shounenki member, namely guitarist Nao.
In Kurohime no Muyuubyou, Sera will be going under a different name than that of his other band. His stage name for this band will be Riiza, meanwhile Nao will also be changing his name; he will now be known as Zeru.
Not much information is known about the band yet, other than their first live, which will take place on May 13 at Shibuya REX. Perhaps more information about a first release will be revealed then. For now, you can check out the band’s profile pictures below, as well as a prologue video the new band uploaded to Youtube.
 Vocalist Riiza, formerly know as Kou in Shounenki, and currently under the name Sera in Hakujitsu no Yume. |  Guitarist Zeru, formerly known as Nao in Shounenki. |
