Mawaru Penguindrum, Sarazanmai Recommendations
If you like any show directed by Ikuhara and want something similar, you have to watch another show by Ikuhara. This is because his anime isn't similar to anything else besides his own stuff.
Mawaru Penguindrum is a surreal story of two boys doing his best to save the life of their little sister - full of metaphores, great animation and beautiful magical girl-like sequences. It's a story about destiny.
Sarazanmai is a surreal story of three boys who are trying to keep connections with other people. Also full of metaphores, great animation and beautiful magical girl-like sequences. It's a story about connection.
Both shows are equally
Both anime have a similar, colourful and surreal artstyle. The humour in both is also pretty similar. They both have outlandish visuals, and a storyline that seems to focus on relationships and people's insecurity in themselves.
Both series also seem to have quite a lot of symbolism and foreshadowing.
The artstyle, the way it's directed the comedy that has a deeper meaning hidden behind it are all similar.
Both of these shows share the same wild director that is Ikuhara, thus it speaks for itself that these two shows would be similar. However, if you are interested in Ikuhara's work you would find that these two shows are the most similar. Sarazanmai and Penguindrum share the most striking similarities out of all his work. Worth a shot if you like one or the other!
