Pretty simple. Japanese singer's name (Merami(pop), or めらみぽっぷ) + fan. Incredible treble, top-notch skill, good range, very wide variety, and quite prolific (over 1,250 songs across 500+ releases). Was signed to a label for some years, but is mostly active in non-commercial, self-published works. Some samples:
Sample 1
Sample 2
Sample 3
Sample 4
Sample 5
And of course, she has real talent.
Live recording here. She was still improving at this point, too (10 years ago). Notably better live renditions compared to some of the album versions of earlier songs.
You can read more about her on my blog, linked in my Twitter bio (@Merami_fan).
Different names for different places, although I use this name for Twitter and other forums with next to no personal info attached to it.
