Yoshitoshi Matabe Ijiri

Yoshitoshi Matabe Ijiri (井尻又兵衛由俊) is the main character of the 10th film of Crayon Shin-chan, The Battle of the Warring States. He is Ren Kasuga's childhood friend and serves as a samurai for the Kasuga clan. He is 30 years old.

He liked to always look at the clouds on the sky, so he was known as the "Blue Sky Samurai", and his banner was modeled as blue background with a white cloud. He was an expert fighter that inspired terror in his enemies, being then called "The Devil Samurai". However, he was really with women and never dared to tell his true feelings to Ren. He lived in the Kasuga fort, with Goemon and his wife Osato. He had no family, as his mother died of illness and his father and brother died in the war..

At the beginning of the film, his life was saved by Shinnosuke disturbing two hiding enemy soldiers that were about to shoot at him. He won all his fights during the movie, protecting Ren and the people of Kasuga. After defeating Lord Okurai, he was shot to death by an anonymous soldier that had already agreed to surrender.

In the real action-film Ballad, he was portrayed by Tsuyoshi Kusanagi (草彅 剛). The character in the real-actors movie and in the animated one has almost the same attitudes and habilities.

He also appeared on the episodes 676-2, 677-2, 678-2, 679-1 and 679-2, released as a promotion for the Ballad movie, along with Ren. In the first two, Shinnosuke and his friends travel in time back to Matabe's childhood to recover a fan with fantastic powers. In 678, ancestors of Shinnosuke and his friends go with teenagers Matabe and Ren to an amusement park. Matabe and Ren seem not to remember any of these happenings in the main film. Finally, in 679 reincarnations of Matabe and Ren appear in present day Kasukabe and meet in the park.
