Adventure could also be a theme. Maybe their love stories are intertwined with quests or travels. As half - elves, they might embark on adventures together, facing various challenges that test their relationship and help them grow both as individuals and as a couple.
Well, the half - elves themselves are surely main characters. There might be a male half - elf who is brave and kind, with his elven grace and human tenacity. And a female half - elf who is perhaps intelligent and beautiful, with a unique charm that comes from her mixed heritage.
Power and power struggles are significant themes. Different groups or individuals may be vying for power, which can lead to conflicts. Additionally, the theme of discovery is there. The characters are constantly discovering new things about their world, whether it's a new place, a new ability, or a hidden truth.
One of the main themes could be survival. In a post - fall world, characters likely have to fight for their lives against various threats. Another theme might be the re - building of society. As the old world has fallen, there's the process of starting anew. And also, there could be a theme of self - discovery, as the characters navigate this new and dangerous world and learn more about themselves.
It could be because humans have unique qualities that attract elves, like bravery or kindness.
One of the main themes is the struggle for survival. Just like in the main 'Attack on Titan' series, characters in 'Before the Fall' face the constant threat of Titans. Another theme is the exploration of human nature. We see different characters react in various ways to the extreme situation of living in a world with Titans. Some show great courage, while others are consumed by fear.
Power and ambition are common themes. The dark elves are often depicted as being highly ambitious, constantly vying for power within their society. Another theme could be loyalty and betrayal. Characters may have to choose between loyalty to their kin or following their own desires, which can lead to acts of betrayal.
Typically, themes of family relationships might be prominent since it involves a half - sister. There could also be elements of adventure as is common in many light novels.
The main themes include love, of course. Rito's harem - like situation where he has feelings for multiple girls and they have feelings for him in different ways is a big part of it. There's also the theme of acceptance. The humans in the story have to accept the presence of the aliens, and the aliens have to accept human ways. This creates a lot of interesting scenarios and character development throughout the 'To Love Ru' light novel.
Well, often in such a light novel, the exploration of human nature could be a theme. The concept of a 'parasite in love' might lead to an examination of how people act and react when they are in a relationship that has an element of 'parasitism'. It could show how self - interest and the need for connection coexist. For example, one character might be using the other in some way, but still have genuine feelings of love, creating a complex emotional and moral landscape.
Love is the obvious main theme. It likely explores different aspects of love, such as first love, unrequited love or the development of a romantic relationship.
