Deletion of List of The Idolmaster characters

Comment: Firstly, there ''is'' no "parent article" for this to be merged to, as the article is a compilation of all characters in the ''Idolmaster'' series - yet each game in the series has its own, different set of characters. Secondly, ''Idolmaster'' is a franchise made in Japan exclusively for the Japanese market - so there's the |usual trouble if one searches for RS coverage only in English (which I suspect the nominator has done), as most sources will be in Japanese. After picking some characters randomly, a Google News search for "https://www.google.com/search?q=%E5%A4%A9%E6%B5%B7+%E6%98%A5%E9%A6%99&oq=%E5%A4%A9%E6%B5%B7+%E6%98%A5%E9%A6%99&tbm=nws 天海 春香" (one of the characters) nets plenty of sources. Similarly, so does "https://www.google.com/search?q=天海+春香&oq=天海+春香&tbm=nws 島村 卯月", another randomly chosen character. A case for  can easily be made here
