In my opinion, 'Hellsing' can also be considered. While it's more action - packed, the relationship between Alucard and Integra has some elements of a love story. Alucard's loyalty and his unique connection to Integra add a different kind of love - like aspect to the anime, set in a world full of vampires and other supernatural beings.
Another great one is 'Diabolik Lovers'. It tells the story of a girl who gets involved with a group of vampire brothers. The relationships are intense and there's a lot of dark romance as she tries to navigate her feelings for each of them.
'Seraph of the End' also has elements of a vampire love story. In this post - apocalyptic anime, the main character Yuuichiro has a relationship with Mikaela, who becomes a vampire. Their bond is tested throughout the series as they are on different sides of the human - vampire conflict.
Another is 'Diabolik Lovers'. It focuses on a girl who finds herself in a house full of vampire brothers. There are a lot of intense and sometimes twisted love - hate relationships among the characters that make for an interesting love story in the vampire setting.
Another one is 'Tsuki ga Kirei'. This anime presents a very realistic and relatable love story. It follows two junior high school students as they gradually fall in love. It shows the small, everyday moments between them, like sharing a book or waiting for each other after school, which makes the love story feel very genuine.
'Clannad' is also an excellent anime with a love story. It focuses on the life of Tomoya Okazaki, a delinquent - like student, and Nagisa Furukawa, a shy girl. Their relationship blossoms slowly as they face various challenges in life together, and the anime also delves into themes of family and friendship along with their love story.
Another is 'Clannad'. The love story in it is complex and heartwarming. Tomoya and Nagisa's relationship develops gradually. They face many difficulties together, and their love grows stronger through all the hardships. It shows how love can be a powerful force for change and growth in people's lives.
A good vampire anime love story often has a strong and unique setting. For example, a world where vampires and humans have a special coexistence rule. The characters should be well - developed. The vampire characters usually have a mix of alluring charm and a hint of danger. And of course, the love story itself should be engaging. It could be a forbidden love, like in 'Vampire Knight' where a human - vampire relationship is not fully accepted in their society.
Probably 'Vampire Knight'. It has a large fan base. The love story in it is very appealing as it combines the allure of vampires with the classic theme of a love triangle. The characters are well - developed and the story has a lot of twists and turns that keep viewers engaged.
Another anime with a great love story is 'Clannad'. The relationship between Tomoya Okazaki and Nagisa Furukawa is really touching. Tomoya is a delinquent at first, but Nagisa, a shy and kind girl, changes him. They go through a lot of difficulties together, including Nagisa's health problems. Their love grows over time, and the story also shows how their love affects their families and friends. It's a story that not only focuses on the romantic love between the two main characters but also on the broader concept of family and love in a community.
