artist: Yasamata Shiyami
artist: SHIYAMI

Masaya Miyashita is the real name of the artist using pseudonyms "SHIYAMI" or "Yasamata Shiyami". A few years ago, this artist had been arrested for publishing doujinshi. I don't know if the regulatory troubles had resulted in the artist using multiple pseudonyms or different ones since 2008 (how annoying!). An overview of what happened is at:

The circle "S-Plus" is the most stable doujin reference for this artist. The artist used various names such as "SHIYAMI" or "Yasamata Shiyami" for doujin and PC HCG works while maintaining his professional artist name as Masaya Miyashita.

See the artist's archived homepages for proof of the various names he used:

So, do all the different works by the artist as "shiyami" and "yasamata shiyami" get aggregated under the artist's real name of "Masaya Miyashita"? It would be quite a change for a bunch of entries.
