Description of Anomaly:
The Pretenders are a group of entities that target Seekers of the Heart of Little Tunes through the mimicry of the whistling calls of the Heart of Little Tunes. Seekers who respond will immediately get physically attacked by the Pretenders and will find themselves unable to harm the Pretenders in any method, with all their attacks seeming to have no affect on them.
According to survivors, various humanlike beings consist of the Pretenders (whether this is based on any form(s) of the Heart of Little Tunes is unknown, given that the latter has not been seen by anyone, not even deities).

Their music have been a great contributors to the Public Domain: glorious tunes that have been rendered by many in their own way.
Well, I have measured the Song Essence of the music notes of the Pretenders. And it is clear:
They all share great similarities with that of the notes of the Heart of Little Tunes
Maybe it's a tribute.
Or maybe it's a cruel mockery.
Maybe they want the Heart of Little Tunes to meet them.
Maybe this is an attempt to lure out Little Tunes.
Maybe they all want to be the Heart of Little Tunes and this is all their individual attempt to take over the Conceptual Essence of the Heart of Little Tunes through a Song Essence Supersede Ritual.
Or maybe it's just their fancy.
The Heart of Little Tunes is a mystery; even the Wanderer's Library does not say much.
I guess it is fitting then for the Pretenders to be a mystery too.
