The author could try to justify it by some kind of mind - control or dark magic. Maybe an enemy has taken over Naruto's mind and forces him to do it without his full awareness.
This type of fanfiction often dives into the psychological aspects of the characters. The kidnapped mate may experience a range of emotions such as fear, anger, and confusion at first. As the story progresses, they might start to see Klaus in a different light. The writer could also introduce other characters who react to this situation, either trying to rescue the mate or siding with Klaus, which adds more layers to the story.
Klaus shows his love by protecting Caroline. He would always be there to save her from any danger, whether it's from other vampires or supernatural threats.
The following are a few recommended novels where the protagonist kills the enemy with a heavy halberd:
1. " I Possessed Lu Bu ": The main character becomes Lu Bu, wielding the Heavenly Halberd, and becomes famous in the dynasty struggle.
2. [Evil Martial Divine Emperor]: A down-and-out young man awakens his bloodline, wields the world-suppressing Evil Halberd, and with a single halberd, he suppresses all directions, ruling the nine heavens and ten lands as the emperor.
3. [Poison Seizes the World]: The story of the protagonist fighting against the world with a halberd hidden under his sleeve.
I hope these recommendations will meet your needs.
I recommend "The Broken Clan". It's a traditional wuxia novel. The main character, Li San, killed his own mother when he was very young. Later, he was brought into the Broken Clan, an assassin organization that had been passed down for thousands of years in the Divine Dragon Continent. He helped the clan to become rich, eliminate traitors, and solve many problems. After that, he began to travel the Jianghu. He was captured by the Horse Gang, pirates, and bandits one after another. Then, he escaped death again and again through his own wit. In the face of the continuous pursuit of the Ancient Tomb Sect, could he still turn danger into safety? Facing the girl they loved, could they finally be together? The road to Jianghu was long, and there was still a long way to go. I hope you like this fairy's recommendation. Muah ~😗
It could be Caroline. They had a complex relationship on the show. Their interactions were filled with tension and attraction, so it's possible that in the fanfiction, they had a child together.
There were a few novels that met the requirements of the main character to kill enemies. Among them," I Can Obtain Proficiency " was a recommended novel. The protagonist collected the martial arts proficiency of the dead by killing them and used it to improve his own abilities, including agility, spirit, internal energy, and so on. In addition,'One Man Killing Doomsday: I Kill the Enemies to Burst Attributes...'
" The Book of the Confucian Sword " was a traditional martial arts novel. It told the story of the protagonist's revenge after his family was destroyed. In the beginning, the protagonist's parents were attacked by enemies, the protagonist's father was killed, and the protagonist was hidden in a cellar when he was young. This novel was in line with the given storyline. It was a well-designed novel with ups and downs and bizarre twists and turns. He believed that it would bring the readers a full pleasure in reading. I hope the readers will like this novel.
The novel I recommend to you is The Strongest Immortal Emperor in the City. This book belongs to the category of urban supernatural novels. The main character was an abandoned young master of the Yuan family who was called a good-for-nothing. When he was investigating the cause of his mother's death, he accidentally transmigrated to the immortal cultivation world. When he returned to the city, what kind of bloody storm would he set off? After he became stronger, he came back and saw that his mother was being bullied. He decisively killed the woman who bullied him. I hope you like my recommendation.😗
The female protagonist was reborn and lived and grew up after she was two years old. The male protagonist was the female protagonist's unrelated brother, the stepmother's child, and the female protagonist's father. There were space, supernatural powers, and love in the story. I hope you like my recommendation.
