Risky Game actually does not go super low, and is within the range of many female singers. The other component of being a ryouseirui, masculine tone, was not present either - her tone is markedly feminine, even on low notes. Finally, none of the ryouseirui-related tags were present on her NND video.

By the way, "reaching Len's range" would not be an indicator of any female ryouseirui because his voice is most known for being a "high male voice" and thus more impressive for males to reach, rather than females.
