Kubiwan’s Ending

As Hideo and Inertia were invading a town, they are again faced with the mysterious White Knight who was sabotaging their plans. Since Hideo noticed that the White Knight was quite powerful, almost at the same level as Inertia, he then proposed to the White Knight to help him kill Inertia together. When Hideo created an opening for the White Knight’s sword to pierce through Inertia's chest, he then started to attack the White Knight, believing that he would end up getting slayed when Inertia gets killed.

To his surprise, Hideo found out that the identity of the mysterious White Knight is actually Kubiwan. Inertia, who then had her wounds completely healed ordered Hideo to finish her off but he couldn't bring himself to do it. As Inertia laughed at him, she revealed the truth between him and his sister Lilfina. Back then, Inertia casted a charming spell to Lilfina, causing her to get very sexually aroused which promoted her to commit incest with Hideo. This eventually became widely known to the villagers and most of them were disgusted. In addition, Lilfina also served as a prostitute for the villagers in order to gain some money to support herself and Hideo.

Given that Hideo believed that Lilfina got killed by demons, Inertia revealed that it was actually the villagers doing. She whispered to them that Lilfina was pregnant with a demon's child which prompted them to kill her. Inertia then explained that the reason why she did all of this was for the sake of her sadistic tendencies on watching Hideo suffer as he was merely used as a tool for her own entertainment while aiming to bring back the demon king.

Realizing that the enemy he swore to exact his revenge upon was Inertia all along, he planned out on how to kill her. Just then, Kubiwan slashed her sword on Inertia, injuring her again before receiving a roundhouse kick. Inertia then charged towards Hideo as he made his next move to defeat Inertia once and for all. Later on, Hideo is seen with Kubiwan who's about to meet the demon king that got resurrected. He, alongside the demons, starts preparing for a real battle.

Marika’s & Ririka’s Ending

By the time Hideo woke up after an intense battle from invading a town, he suddenly saw Marika & Ririka on his bed partially naked. They then started to express their love for him, which led them to have sex. Afterwards, Marika and Ririka sealed away the demons (Damsel and Zetro) from both of Hideo's hands. The scene then cuts to them going on a journey far North from the imperial capital to find the legendary sword called "Sonata Arctica" that can be used to destroy the Demon King. It has been revealed that both of these girls already sensed a demonic presence within Hideo long ago ever since he took residence in the castle. Back when they were having sex from that morning, they used one of their secret magical techniques where they surrounded Hideo in their magical circle to eradicate the demonic essence before he ended up being consumed by the demonic urges. Hideo then questioned about his past actions when he was still consumed with anger and plotted a revenge scheme for the sake of his deceased sister Lilfina. However, he acknowledged that both Marika and Ririka helped him redeem his life as they forgave him for his past actions. They happily continue on their journey to find the legendary sword while Marika and Ririka tease each other along the way.

Mutsuki Yukari’s Ending

At one point, Hideo admitted to Mutsuki that he was actually the legendary hero that she's been closely affiliated with back when they were fighting against the demons years ago. Mutsuki initially thought he was already dead, and she was completely flabbergasted that the man she loved was still here, alive in the form of a priest. He also admitted to her that he is now siding with the demons for his own personal goal for plotting a revenge, further devastating her.

Later that night, Mutsuki meets Hideo in his room and she sets up a magical barrier to prevent anyone from interrupting them. While she doesn't understand why he became a demon, she still loves him very much and she wanted to have sex with him just like how they did back in the past. Hideo felt a sense of nostalgia and he was overjoyed to have sex with her again. Afterwards, Mutsuki defected from the imperial capital and joined the demon army to stay by Hideo’s side.

Aneirinn’s Ending

After a long rest, Hideo realized that he overslept. It was already late at night and Hideo tried to find Kubiwan, but she was nowhere to be found in his room. He then walked around the castle to try and find her but when he entered the cathedral, he found Aneirinn performing a majestic dancing ritual. After having a brief chat with each other, they started to get intimate and have sex. As Hideo was enjoying the pleasure, the image of Kubiwan suddenly flashes in his mind which confused him. Later on, his body became paralyzed and Aneirinn had him confess about his desire to seek revenge for the sake of his sister Lilfina. Aneirinn then smiled and said that she will be with him for his support before erasing his memories and sealing away the demonic essences within his body. The scene then cuts to them as a married couple working at a tavern.

Iria Regate’s Ending

Even since Hideo took over the body of Iria’s brother Andersen, the memories of Andersen ended up getting merged into Hideo’s mind which greatly influenced him to be more loving towards her. By dawn, Iria who is still oblivious to the fact that Hideo is disguising himself as her brother, meets him in his room where they start getting intimate towards each other. Iria mentioned that she believed that her brother Andersen would’ve been a suitable knight to protect and serve the country. However, Andersen threw away his sword for the sake of his sister Iria which is what she truly loved about him. Hideo is fully aware he is not Andersen and he recalls his desire for revenge for the sake of his deceased sister Lilfina. However, he was greatly touched by Iria's love and compassion which reminded him about his moments with Lilfina back then.

After having sex, Iria mentioned that her father had organized an arranged marriage for her with another man. With a strong desire for both of them to be together, Hideo and Iria made preparations to flee from the imperial capital. Hideo also wrapped both of his hands with bandages as a temporary measure to seal away the two demons (Damsel and Zetro). He doesn't know how long he'll be able to keep up posing as Iria's brother Andersen, but if a moment ever arrives where his mind gets completely consumed by demonic urges, he will greatly accept Iria to slay him. They then proceeded to go somewhere that no one will ever find them and they promised to each other that they'll always be together. Hideo ensures he’ll do whatever he can to stay as Iria's brother until the very end.

Tristyna Eltorlida’s Ending

At night, princess Tristyna noticed that the demons were attacking the castle. She quickly rushed over to Hideo's room, guiding him to a secret underground passage to flee from the castle. While she was oblivious to the fact that Hideo was actually aiming to use her as a sacrifice to resurrect the demon king, Tristyna started to realize that Hideo who was posing as a priest is actually the legendary hero that fought for her country against the demons long ago. 

When they started to rest at a nearby room, Tristyna’s kindness and compassion was touched by Hideo as she understood the tough times he’s been through back then while protecting the country. He gradually became more attached towards Tristyna and he knew that if her virginity gets taken, she will no longer be eligible to be used as a sacrifice to resurrect the demon king which he later admitted about this to her. Tristyna then offered her body to him as she understood the situation.

Afterwards, Hideo became the new emperor of the imperial capital and married Tristyna. It was implied that because Hideo took Tristyna's virginity, the resurrection of the demon king was simply delayed which implies that the demons are searching for a new sacrifice. As the battle against the demons goes on, Hideo and Tristyna happily serve as the new rulers of the imperial capital.

Creole’s Ending

At dawn, Creole with her body temperature being abnormally high, meets Hideo in his room. She explained that her body is currently in a state that has a strong desire to copulate with the opposite gender. This normally happens to all demi-humans like herself whenever the moon is at certain phases, however Hideo suspects that Creole’s state is also caused by his actions on weakening the magical barrier of the castle. Hideo then asked Creole why she specifically came to him, and she said that she did it out of instinct. They eventually became intimate towards each other and ended up having sex to satiate Creole's lust.

Afterwards, Creole talked about her past life being rough as a demi-human ever since she was a child. People shunned her especially when her body became sexually active which coerced her into holding back her urges. However, Hideo was different from most people as he accepted her for who she is which is the main reason why she dedicated herself to him. This suggests that Creole really is in love with Hideo.

Creole also mentioned that her services as a maid are no longer needed in the castle and she's been ordered to leave. Touched by Creole's warmth and kindness, Hideo doesn't want to leave her side, especially after learning the harsh treatments demi-humans normally get in the country. He then decided to seal away the demons (Damsel and Zetro) from his hands with the help of Marika's magic and spent the rest of his life as a real priest, working at an orphanage in a rural area with Creole. They happily live together as a married couple with their demi-human child.
