傾福さん

《Keifuku-san》 is a short anime produced by the doujin circle irodori, directed by Tatsuki, and voiced by Yumiri Hanamori. The anime was first released on Tatsuki's Twitter in August 2017, followed by a sequel in October, and a full version on YouTube in December. Known for its unique visual style and mysterious world, it combines 3D modeling with hand-drawn backgrounds. The story revolves around a station attendant-like girl and her talking, translucent manta ray companion as they collect mysterious objects called 'tama' along a tilted railway and transport them using sea turtles. Despite its simple plot, the anime is filled with details that have sparked various interpretations among viewers. The work was also commercially successful, with DVD sales topping the Amazon and Oricon charts. Some critics believe the work is a form of support and donation by fans to director Tatsuki after the 'Kemono Friends' controversy. The origin of the name 'Keifuku-san' is still unknown, but some speculate it may be related to producer Yoshimasa Fukuhara, and that the plot may be linked to the production process of 'Kemurikusa'.
