Kunihiko IKUHARA (幾原邦彦) is a Japanese director, writer, artist, and music producer. He has created and collaborated on several notable anime and manga series, including his early works Sailor Moon and Revolutionary Girl Utena, and his later works Mawaru Penguindrum, Yurikuma Arashi, and Sarazanmai. He has done various collaboration with other artists, such as Asumiko Nakamura (Nokemono to Hanayome THE MANGA).
The last book was marginally better than the first two, as it finally decided to go into a little more detail about certain scenes and add more flavor to others, instead of simply recounting scenes from the anime with the blandest tone. However, some of the changes made to the narrative were not to my liking. In the end, the anime is the better experience 100%.
