This site was one of the best Yami no Matsuei resources out there, offering LOTS of Hana to Yume and doujinshi scans, along with the her brilliant "Continuity Errors" and many, many other goodies.
Sadly, it would APPEAR that people have been helping themselves to the contents of Kohakutenshi's site and distributing the contents without permission or giving her credit. As a result of this, she has taken her site down.
