Ending 1: After Kyousuke and Ai escaped the burning mansion and returned to his home, Kyousuke was still affected by the drug that Ai gave him, which he was still sexually attracted to Ai. Kyousuke later on brought Ai to a public park at night where she had sex with a dog and had semen squirted all over her from other people who were passing by.

Ending 1: After Mushizo killed Kyousuke, we was reincarnated into the body of the Kudan that Yukino gave birth to. The Kudan announces the prophecy in a cryptic language that Mushizo was able to understand which shocked him. The mansion then collapsed resulting in Yukino and Kyousuke (Kudan) to get barried in the rubble.

Ending 2: Yukino underwent various sexual actions with multiple men at the order of Mushizo, including with Kyousuke for the ritual to give birth to Kudan. Afterwards, Mushizo kills Kyousuke right in front of Yukino as he was no longer useful anymore.

Ending 3: (Biggest spoiler of all. Be Warned!) Kyousuke and Yukino were transported to a spaceship and Kyousuke learned the truth about the mansion after having his mind getting flooded with information by some kind of relay system. It turns out this Oshiro-sama that the cult was worshipping wasn't some God or spiritual being but rather an alien from a different universe. These aliens were the ones responsible for conducting these rituals for experiments that they have done for hundreds of years. Their experiment was about predicting the future which is associated to the Kudan that was given birth by the Shrine Maiden. In addition, these aliens manipulated the minds of the people living in the mansion to perceive time slower than normal, and prevent them from getting away from the mansion. The goal for these aliens was to manipulate the law of "cause and effect" by using the prophecy that is announced by the Kudan. Also, the aliens were the reason why Kyousuke and the shrine maidens in the mansion have these prophetic dreams whenever they sleep. They were implanted with "The Power of Enlightenment" and they were used as tools for their goal to manipulate the future at will. Kyousuke was enraged after learning the truth, and he tried to get Yukino back as she was being used as a sacrifice. As a result, the spaceship malfunctioned and the mansion was burning. Kyousuke and Yukino were teleported outside at the boat dock and they successfully escaped. Afterwards, Kyousuke was living happily with Yukino as her new detective assistant. Since Kyousuke was gone for an entire year because of the aliens manipulating his mind on percieving time, Momoko moved to a new detective agency. It was also revealed that Ruriko (Yukino's mother) was the one giving instructions to Mushizo and the cult memebers for the rituals, which was the reason why Yukino experienced those horrendous sexual acts at the mansion. Ruriko's time as a shrine maiden expired and she became jealous when she was replaced by her own daughter Yukino. Yukino was devastated after learning the truth about her mother, but she still managed to live happily with Kyousuke. In addition, Kyousuke promises to protect Yukino and always be by her side.
