Another theme is the power of love to overcome obstacles. Whether it's the difference in species, like in 'Ponyo on the Cliff by the Sea' where Ponyo is a fish - girl and Sosuke is a human, or environmental challenges, love is often portrayed as something that can bridge the gap. Love gives the characters the strength to face difficulties and find a way to be together.
One common theme is the contrast between the two different worlds. In most of these stories, there is the world of the sea and the world of the land. The characters from these different worlds often face challenges in their love due to cultural or physical differences. For example, in 'Nagi - Asu: A Lull in the Sea', the sea - people have different traditions and ways of life compared to the land - dwellers.
Another theme is the power of nature. The ocean can be both a beautiful and a dangerous force in marine love stories. It might bring the lovers together, like when they meet on a beach during a storm, or it can test their love, such as when a character is lost at sea. In 'The Perfect Storm' - related love stories, this is quite evident.
One common theme is the 'forbidden love' aspect. Since Tails is from the land and Marine is from the sea, their different habitats can be seen as a barrier, like in Romeo and Juliet. Another theme is discovery. They discover new things about each other's worlds and themselves through their relationship.
Another theme is sacrifice. Characters might sacrifice their own desires or even their future for the sake of their loved ones. In some action - oriented anime love stories, a character may give up their power or a chance at something great to protect their lover.
One common theme is unrequited love. In many anime, a character loves someone who doesn't initially return those feelings, like in 'Kimi ni Todoke'. Another theme is sacrifice. Characters might sacrifice their own desires or even safety for the sake of their loved ones. Also, growth through love is common. As the characters fall in love, they grow as individuals, like learning to be more confident or understanding in 'Lovely★Complex' where the two main characters with height differences grow together in their relationship.
One common theme is friendship. Just like in the story of Nemo and Crush, marine animals often help each other out in times of need, which shows the importance of friendship in their world. Another theme could be survival. Many stories involve a character facing a difficult situation like a storm or getting lost and having to find a way to survive.
One common theme is adventure. Marine girls often embark on exciting journeys in the ocean, exploring unknown areas. Another theme is friendship. They might form strong bonds with other characters, whether they are other marine girls, sea creatures or humans. And the theme of self - discovery is also present, as they learn about their own abilities and place in the world of the ocean.
One common theme is adventure. For example, sailors going on long and dangerous voyages, exploring uncharted waters. Another is the power of nature. The sea can be calm and beautiful one moment and a terrifying force the next, as seen in many stories about storms at sea. Friendship also often features, like the bond between crew members on a ship.
One common theme is self - discovery. The characters often start out not fully understanding their own feelings or identities, and through their relationships, they learn more about themselves. For example, in 'Citrus', Yuzu has to come to terms with her new - found feelings for Mei.
One common theme is the 'opposites attract' concept. In many anime love comedies, the main characters are very different from each other in personality, appearance or social status. For example, in 'Toradora!', Ryuuji and Taiga are like night and day. Another theme is the struggle with expressing feelings. Characters often find it difficult to confess their love directly, which leads to comical situations as in 'Kaguya - sama: Love is War'.
One common theme is loyalty. In many anime wolf love stories, the wolves are shown to be extremely loyal to their mates or pack members, which is often intertwined with the love aspect. For example, in 'Wolf's Rain', the wolves are loyal to each other during their journey, and this loyalty is part of their love for one another.
