Ajin: Shoutotsu

Ajin: Shoutotsu, also known as Ajin: Collision, was produced by Polygon Pictures as the second installment in a cinematic trilogy based on Gamon Sakurai's dark fantasy manga. Released in 2016, the film serves as a direct continuation of the first entry, transitioning the episodic narrative of the manga into a feature-length cinematic experience. This project marked a significant moment for the studio, as it utilized their distinct 3D cel-shaded animation style to capture the visceral, high-stakes combat and ethical dilemmas inherent to the Ajin universe.

The animation was directed by Hiroyuki Seshita, who sought to maintain the gritty aesthetic of the original manga while navigating the technical challenges of 3D character modeling. The production was largely praised for its fluid action sequences and technical ambition, standing out at the time as a bold experiment in translating long-form seinen manga into a high-fidelity digital format. The film was well-received by audiences for expanding the supernatural world-building and deepening the antagonism between the protagonist, Kei Nagai, and the series' primary antagonist, Sato.
