Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core

Lore & Background

The film is split into three parts. The Kamen Rider W segment, written by Riku Sanjo, takes place between episodes 48 and 49 of the series, where Akiko Narumi prepares for her wedding while her Kamen Rider friends are distracted by the Pteranodon Yummy. Akiko witnesses a memory of her father Sokichi Narumi's past as Kamen Rider Skull, involving a case with opera singer Melissa and a Spider Dopant. The Kamen Rider OOO segment, written by Toshiki Inoue, follows the Kougami Foundation creating a Cell Medal-based homunculus of Oda Nobunaga, who escapes and becomes a fusion of Oda Nobunaga's data with Cell Medals, transforming into a monster called 'Kamen Rider OOO (Nobunaga version)' before being defeated by Eiji Hino.
