An angel to save the earth
Kyoto, end of 20th century. You are Kusakabe Makoto a student and Christmas is coming. A evil monster came back to the earth and is going to be attacked... Well, actually it seems more a story of Duke Nukem games, but it's an hentai. Finally the game is not bad at all, as usual, you will meet several cute girls and to see quite good manga. The style is quite similar to Nocturnal illusion and Paradise Height saga.
