"Plot"-Diary System
A young man awakens in an unfamiliar room. He neither knows where nor who he is.
A mysterious diary, emitting a soft purple glow, resides in the space of his mind. Upon it is the name Ryu Seiya.
After realizing his name, the diary activates the System Integration, and stories of all kinds enter his mind space, filling it like stars and galaxies.
The "Plot"-Diary System tasks him with altering the original progression of the stories. This allows Ryu Seiya to steal the "Fate" that is bestowed upon the Characters from the "Will of the World". This stolen "Fate" is used by the System to grant its Host random abilities in correlation to the characters whose plot has been altered.
To facilitate a subtle method of altering "Fate", the System also grants Copies of the Diary that its Host writes to female characters in the world he enters. Through revealing secrets and future events to these characters, their actions and mindset can be influenced. To further incentivize the so-called Copy Holders to assist the "Plot"-Diary System Host, they receive the same regular rewards as Ryu Seiya.
Join Ryu as he tries to navigate sometimes perilous and sometimes perplexing stories, beginning with "Monster" by Naoki Urasawa, where he tries his best to stop Johan Liebert and other serial killers from harming the innocent.
Experience the romance between a young man and the female characters in various stories that you either love or hate. How will he handle having loved ones in multiple different worlds?
This novel will be slow-paced, and the action will take a backseat compared to his planning and interacting with the Copy Holders. Although the diary in their minds helps forge an emotional bond with Ryu Seiya, the romance will be pretty slow unless the female character is known for forming relationships quickly. For example, Elsa in "Monster".
The chapter length averages around 3.000 words, and due to the way Ryu Seiya interacts with the story worlds, there will be longer pauses for research between arcs. So don't expect extremely fast updates.
I'll try my best to forge a comprehensive narrative with distinctive arcs around the original works, while regularly revisiting the already completed ones and how the members of the Harem use their System-given powers to alter their original world after Ryu is forced to leave for the next story.
There will be lemons, but not frequently. Primarily focusing on the first time Ryu spends with each particular woman. Please note that Ryu loves his wives deeply, and there will be no hierarchy in the Harem, as well as no forced sexual interactions on the side of the main character.
Except for some of his wives who like various styles of play, Ryu will never degrade or talk down to his wives. They are an integral part of this work due to how the "Plot"-Diary System works. So if you want to see a main character who practically enslaves his Harem, this is not the story for you.
Often, Ryu Seiya will also diminish the original protagonists and other male characters in the stories he enters. He has to steal their "Fate" after all, which entails their opportunities, such as finding resources, teachers, and romantic partners. Due to this, he often disparagingly portrays other male characters in his Diary to dissuade the Copy Holders from supporting them as much as possible. This will lead to many pairings of the original works not forming or even breaking up.
The System is non-interactive and has no true intelligence. Except for the introduction and distribution of rewards, its only function is to facilitate the Copy Holders and display of a status page. There will be no System-assigned missions, and the Host has complete freedom in how to tackle each story.
