Both show the main characters struggling to find their place among society.
Each has their own sub theme of romance, though each show explores that field in their own manner.
Both shows are heavy on use of symbolism and both carry themes regarding aspects of society.
Though Koukai no Kanata has a darker situation than Sakurasou no Pet na Kanojo, their central ideas remain very similar.
