Description
Eiji is a young boy who appears in the live-action film Rurouni Kenshin Part II: Kyoto Inferno. His full name is Mishima Eiji, and he originates from Shingetsu Village. This village has been abandoned by the Meiji Government to the machinations of the villainous Shishio Makoto, and is brutally ruled over by one of Shishio's henchmen, a man named Senkaku.

In terms of background, Eiji escapes from his home village in the arms of his older brother, Ei'ichiro. During their flight, Ei'ichiro suffers fatal injuries and dies, leaving Eiji to be found in a forest by the protagonist, Himura Kenshin, and the young kunoichi, Makimachi Misao. The trauma of losing his family, combined with the horror of seeing the village under Shishio's control, has a profound impact on him.

Eiji is a young boy of a slim build with short, scruffy brown hair and fierce brown eyes. As a result of his past trauma, he often has a hard, determined look on his face. His personality is a mix of bravery and naivety. He is passionate and courageous to the point of being brash, willing to stand up to opponents who are far more skilled and experienced than he is. However, his youth has left him sheltered; for example, he is initially unaware that taking revenge by killing has been outlawed in the Meiji era. Despite his hardships, he demonstrates a deep sense of compassion and understanding. He is shown to forgive his fellow villagers for their cowardice in allowing his parents' desecration and ousting him, instead wishing them well. His loyalty to his family is a core part of his character, and he is devastated by the loss of his brother and parents.

Eiji's primary motivation in the story is to free his home village of Shingetsu from Shishio Makoto's influence. He is then escorted back to the village by Kenshin and Misao to confront the oppressors. His personal quest is fueled by a desire for revenge against those who wronged his family, though he must come to terms with the fact that acting on that impulse is illegal in the new era.

His role in the story is that of a catalyst and a representation of the innocent people suffering under Shishio's rise to power. His encounter with Kenshin and Misao gives them a direct, personal reason to confront one of Shishio's men, Senkaku, and to liberate Shingetsu Village. Through him, the film explores the consequences of the new government's failures and the cycle of revenge.

Key relationships for Eiji include his deceased older brother, Ei'ichiro, whom he deeply loved and respected. He forms a bond of friendship with Kenshin and Misao, who protect him and help him on his journey. In a significant development later in the continuity, Eiji is taken in by Saito Hajime, a former Shinsengumi captain turned police officer, and his wife, Saito Tokio, becoming their foster child. This relationship shapes his future, as he eventually becomes a recruit in the military and accompanies Saito on missions, showing a desire to be like both Saito and Kenshin.

As for development, Eiji begins as a traumatized, revenge-driven child but learns through his experiences with Kenshin that there are other ways to achieve justice without becoming a killer himself. He learns that the act of killing for revenge was prohibited in 1873, which forces him to confront his own desires. His character arc continues beyond the events of Kyoto Inferno, as he grows up under Saito's care, eventually learning to use a rifle and deciding to walk his own path as a member of the military, while still holding onto the lessons he learned from Kenshin.

Regarding notable abilities, Eiji is not a highly skilled swordsman like the main characters. His defining trait is his courage rather than any specific combat prowess. He is shown to be brave enough to fight against much stronger opponents with little chance of success. Later in the Hokkaido Arc, he demonstrates proficiency with a rifle, managing to shoot a powerful enemy named Byakuya when an opportunity arises. His primary strength lies in his indomitable spirit and fierce will to protect what remains of his family and his home.
