Identify Name of an old game with main girl in parts

[KageJester]

Hello,

I'm looking for the name of an old hentai game fully in japanese, you play a guy and the main girl on the poster is only a head, probably with red or pink hair but I'm not sure I remember correctly.
There was a magic circle bellow the head as if it was cut by magic and in the game you can retrieve the others parts of the girl to make her whole again.

Thank you in advance

This came in mind.

Thank you for the proposal but it's not this one, I don't even think it is translated in english. I also remember that was made by an official japanese game studio, not an independent one.
