Tentama tells the story of an angel in training that to become a full angel. He has to visit Hayasegawa Shiina and his schoolmates and helps him to be happy, and to do that he has to find a girlfriend in this adventure dating interactive game. In this game, Kid introduced a very interesting system, where you can see the Tentama world from different characters' perspective and their thoughts/feelings at the moment. The player will see most of the time the world from Hayasegawa Shiina perspective, and the angels just tell him if the girls like him or not. The main female character of the game is Enoki Rikako, a first year highschool student that goes to the same highschool as Shiina. She hates ghosts. If the player wins Rikako-chan's heart, he will unlock an omake scenario for Eri-chan that will tell Eri-chan's side of the story.
