From Episodes 40 through 42, the Western Ashu Ouga aims to killed Eiji because his mother, Kei's soul cannot complete it's travel to the other world with Eiji still alive. Eiji performs the Áshu Soul Vanishing, but Ouga takes Eiji's soul with him, leaving nothing but a petrified body. Eiji is transported to Purgatory where he meets his mother or who he believes to be her. She takes him to their home and gives him supper but it ends up being Ouga himself. Kei's spirit gives him his old staff to vanish Ouga and she transports him back to the living. When their Boukenger powers were purged, Eiji returned home exhausted and was visited by the spirit of his mother, who told him he accomplished the Takaoka family mission. She made him realize he sought adventure and he continued with the Boukenger. In 'Boukenger vs. Super Sentai,' his five teammates were kidnapped by Chronos into another dimension and he was recruited by AkaRed to recruit four veteran Sentai Warriors. Eiji, who wasn't much of a team player to begin with, had to pull together the four who weren't used to working with each other to save his friends. Ultimately, Eiji had an understanding for AkaRed.
