The main character in the 'Regressor of the Fallen Family' novel is typically the one around whom the story revolves. They are likely to be the one with the regressor ability. This character probably has to face a lot of challenges related to the downfall of their family, like dealing with debts, family feuds, or loss of status, and uses their regressor power to try and turn things around.
Probably family restoration. Since it's about a regressor in a fallen family, trying to bring the family back to its former state would be a main theme.
One of the main themes is redemption. The regressor is likely trying to make up for the downfall of their family in the past. Another theme could be power struggle as they might need to gain power to restore their family's status.
Power and growth are also significant themes. The main character has to gain power to change the fate of the fallen family. There's also the theme of facing challenges. He has to deal with various obstacles in his regressed journey, which shows his struggle and the will to overcome difficulties.
A novel named 'Omniscient Reader's Viewpoint' might be relevant. It has a unique premise where the protagonist uses his knowledge from reading a web novel to survive in a world that has become like the novel he read. Just like in 'Regressor of the Fallen Family Raw Novel', the characters have to adapt to strange and difficult situations using their own abilities and knowledge.
Well, 'The Beginning After the End' might be a good recommendation. It shares the theme of a character with special abilities and a journey of growth, much like in 'Regressor of the Fallen Family'. There are also elements of strategy and development in both.
In a 'past life regressor novel', the main character is, of course, the one who can regress to past lives. This character is usually on a quest of some sort. There could also be a love interest, someone who has a connection to the regressor's past and present lives. And then there might be an enemy, perhaps someone who fears what the regressor might change in the past that could affect the present or future. For example, in some novels, there could be a powerful wizard or a corrupt noble who wants to keep the status quo and thus tries to stop the regressor.
The main character is likely to be the one who is thrust into the situation of past life regression. They would be at the center of the story, facing challenges and making discoveries. There could also be supporting characters such as friends or family members from the current life who react to the protagonist's new - found knowledge of their past. And perhaps there are characters from the past lives who play important roles in the overall plot, like old enemies or long - lost loves.
I don't know specifically since I haven't read this light novel. But typically, there would be the main character who is the past life regressor. There might also be characters from their past life like friends, family, or foes that they interact with during their regression.
I recommend " The Blood Clan's Love: The Demon King Dotes on His Wife " and " Slaughter: Angel of Revenge " to you. These two novels were otherworldly novels with fallen angels as the main characters. " The Blood Clan: The Demon King Dotes on His Wife " told the story of a girl who accidentally became a vampire hunter and the legendary fallen angel, Satan, while " Slaughter: The Angel of Revenge " told the story of a fallen angel who carried the goal of revenge. I hope you like my recommendation.
I recommend "The Blood Clan: The Demon King Dotes on His Wife" and "Slaughter: Angel of Revenge." The former was about the love story between a fallen angel and a vampire girl, while the latter was about the revenge of the last fallen angel with black wings on his back. I hope you like this fairy's recommendation. Muah ~😗
