It could also be due to a malfunction or some form of corrupted programming. Maybe a virus or a glitch in his system has made him misinterpret the other pet AIs' actions as hostile, causing him to attack. For instance, if his perception algorithms are faulty, he might see an innocent gesture from another AI as an attack and retaliate.
I'm not sure specifically as it could be a very niche fan - created story. It might be a fanfic that involves Riki from 'AI no Kusabi' in a situation where he is being punished in some way, perhaps related to the power dynamics and complex relationships within the story's setting.
There could potentially be some fanfiction out there with such a theme, but it's not something that is widely known or promoted. 'Ai no Kusabi' has a rich world and complex characters, and while some writers might explore darker themes, it's hard to say for certain without a thorough search of all the available fanfiction platforms. And if such fanfiction does exist, it should be approached with caution as the topic of abuse is a sensitive one.
Love and sacrifice are also common themes. Riki has relationships that are full of challenges. Fanfictions often explore how he loves others and what he is willing to sacrifice for those he cares about. It could be his freedom, his status, or even his life in some extreme cases. These themes add depth to the character and make the fanfiction more engaging.
First, understand the character of Riki well. Know his backstory, his personality traits like his determination, his vulnerability, and his loyalty from the original AI no Kusabi. Then, create a unique situation for him. It could be a new adventure, a different relationship dynamic, or a personal crisis that he has to face. For example, you could put him in a situation where he has to make a difficult choice between his friends and his own beliefs.
Some characters might be shocked. They may not have expected Riki to be so aggressive. They could try to stop the fight immediately, fearing that it could lead to more chaos or damage in their environment. For example, a peace - loving character would be horrified at the sudden display of violence.
You can try searching on some well - known fanfic platforms like Archive of Our Own (AO3). They have a large collection of fanfics from various fandoms.
One common theme is the complex relationships between the characters. For example, the power dynamics between different castes in the 'Ai no Kusabi' world are often explored. Another theme is the struggle for freedom and identity. Characters like Riki are often depicted as trying to break free from the constraints of the society they live in. Also, the exploration of the unique culture and settings of the 'Ai no Kusabi' universe is quite common, such as the different regions and how they function.
One possible motive could be mind control. Maybe an enemy uses some kind of jutsu to make Naruto lose control and attack Sakura. Another could be a misunderstanding. For example, if Sakura was framed for something really bad, and Naruto in his hot - headedness believes it and attacks her. Or perhaps in a dark, alternate universe version of the Naruto world where the characters' personalities are twisted, Naruto might have a reason to attack her based on that altered personality.
One possible motive could be that he's been mind - controlled. There are many villains in the Fairy Tail universe who have the ability to control others. Another reason might be a misunderstanding. Maybe he thought Fairy Tail had betrayed him in some way. It could also be a result of some dark magic that has affected his judgment.
One common theme might be the relationships between the characters. Given the nature of the original work, themes of loyalty and power dynamics could also be prevalent.
