Is there a source for this character's tie to MGE? It seems to be an original character called Reri judging from the source of this post (as well as the source of her original appearance on Danbooru, post #2222023), though it was a commission. Compare to MGE's manticore design in post #1770915.
I found one artist stating that it is "an alternate version of the manticore monster girl" but that's about as deep as I got. I can't find anything directly from Kenkou Cross with the character looking like, yet Danbooru isn't the only place I see her associated with MGE, curious to know the origin here (as well as if the tags are as they should be).
She's an original MGE manticore. A manticore with a different appearance. While that might deserve alternate_hair_color/hairstyle/etc. tags, keep in mind that MGE profiles are supposed to depict an average member of the species, not their "one and only appearance".
