Since we don't have much information about this specific'shuumatsu visual novel', it could be about various things. It might be a fantasy - based story set at the end of a magical age. The characters could be dealing with the decline of magic and having to adapt to a new world order. Or it could be a psychological exploration where the 'end' is more of an internal state for the characters, such as the end of their beliefs or values, and the visual novel follows their journey of self - discovery and transformation in the face of this internal 'end'.
Another interesting plot could be a love story. Picture a character from RWBY falling in love with a character from Shuumatsu no Valkyrie. This would face many challenges, such as the differences in their worlds, cultures, and the fact that they are both often in the middle of dangerous situations. But their love could be a force that brings their two worlds closer together.
The Disney story of Hercules has some basis in the real myth. The core idea of Hercules being a heroic figure with extraordinary strength is there. But Disney simplified and modified a great deal. In the real myth, Hercules had to complete the Twelve Labors which were often quite dark and difficult. Disney took that concept and made it into a more upbeat and less gory adventure for kids. Also, the way Hercules' character is developed in Disney is different from the more complex and often flawed character in the original myth.
One of his main adventures was the Twelve Labors. He had to perform tasks like slaying the Nemean Lion, which had an impenetrable hide. Another was cleaning the Augean stables in a single day. He also captured the Erymanthian Boar.
Well, a big spoiler in the 'Shuumatsu Nani Shitemasu' light novel is that some of the main characters' backstories are far more tragic than you might initially expect. Their pasts are what shape their actions and decisions in the post - apocalyptic world. For example, one character has a past that involves a great loss which makes them extremely protective of the group they are with later on.
One unique feature could be its complex characters. The characters in shuumatsu light novel are often multi - faceted, with their own motives and backstories that drive the plot. For example, the main character might have a hidden past that gradually unfolds throughout the story, adding depth to the narrative.
There might be a mentor - like character as well. This character could be an older and wiser figure who guides the protagonist. They might have special knowledge or powers that are crucial for the protagonist's development. For example, they could teach the protagonist how to use a certain magic or skill.
It's about a battle royale - style setup where gods from different mythologies battle against humans. The Valkyries play a role in setting up these battles.
The 'Shuumatsu no Harem' light novel is set in a world where a virus has wiped out most of the male population. The story follows the remaining male protagonist as he navigates a world filled with various female characters. It involves themes of survival, relationships, and the rebuilding of society in this new, male - scarce environment.
I'm not entirely sure as I haven't read it in detail. But generally, it might be a novel that involves a harem theme, perhaps set in a unique or fantastical world. Maybe it has a male protagonist surrounded by multiple female characters with various relationships and adventures.
