When mankind's savagery surpasses his fear of death, there is little hope for those who wish to live honest lives. Beneath a full moon, a young boy witnesses the murder of the bandits who had enslaved him, and is then christened with a new name by the man who rescued him. This boy is Shinta, now known as Kenshin Himura, and he is destined to become a swordsman. The softness of his heart does not befit the occupation, but his desire to protect the innocent is absolute. Rurouni Kenshin: Meiji Kenkaku Romantan - Tsuioku-hen details the origins of the man who would bear the name of Hitokiri Battousai long before he swore his oath not to kill and before he earned his reputation as an assassin. The young man's heart is divided between justice and corruption, while the fate of a nation rests on his actions.

Ten years have passed since the end of Bakumatsu, an era of war that saw the uprising of citizens against the Tokugawa shogunate. The revolutionaries wanted to create a time of peace, and a thriving country free from oppression. The new age of Meiji has come, but peace has not yet been achieved. Swords are banned but people are still murdered in the streets. Orphans of war veterans are left with nowhere to go, while the government seems content to just line their pockets with money. One wandering samurai, Kenshin Himura, still works to make sure the values he fought for are worth the lives spent to bring about the new era. Once known as Hitokiri Battousai, he was feared as the most ruthless killer of all the revolutionaries. Now haunted by guilt, Kenshin has sworn never to kill again in atonement for the lives he took, and he may never know peace until killing is a thing of the past. Now in the 11th year of Meiji, Kenshin stumbles upon Kaoru Kamiya, owner and head instructor of a small dojo being threatened to close its doors. The police force is powerless to stop the string of murders done in the name of her dojo by a man claiming to be the famous Battousai. Kenshin's wanderings pause for now as he joins Kaoru to clear both their names. But how long can he stay before his past catches up to him?

In the late 19th century, as the cruel times of the Bakumatsu period came to a close, a new Meiji era marked the age of restoration for Japan. With the war over, its infamous hero Hitokiri Battousai disappeared into thin air, leaving only his legend behind. Years later, a seemingly plain wanderer named Kenshin Himura encounters Kaoru Kamiya, the owner of a struggling local dojo in Tokyo. Kaoru pursues a self-proclaimed Battousai who roams the streets, indiscriminately killing citizens and police officers. Furthermore, the warrior professes to use the Kamiya Kasshin-ryu—a sword style developed by Kaoru's father deeply rooted in the essence of life, not death. Kenshin decides to help Kaoru take down the impostor and restore her father's dojo. Unbeknownst to all, Kenshin is none other than the real warrior whose name still terrifies the people. Although Kaoru eventually learns the truth, his oath to atone for his murderous history by bloodlessly protecting the weak moves her, and she welcomes Kenshin to stay at her dojo. However, Kenshin's ideals are soon challenged by ghosts of the past and enemies of the present.

Kaoru goes to the harbor every day to see if Kenshin has returned. After a while, she starts looking back at her life with Kenshin and all the things that have happened.

A large scale remake of the time after Kenshin leaves Tokyo up until before the inferno of Kyoto.

In the days before the Japanese Revolution, Hiko Seiijuro, a wandering master swordsman and hermit, encounters a bandit raid on a slave wagon. Hiko kills the raiding bandits in hopes of saving as many lives as possible, but only manages to spare one life from the massacre. Hiko leaves the child, advising him to go to the nearby village and have them take care of him. A few days later, as Hiko comes back to check upon the child he saved, he is shocked to see the child had created graves, both for the slaves he befriended and the bandits who killed them. Seeing potential in the young one, Hiko takes the child under his wing, names him Kenshin, meaning "heart of sword," and teaches him about the art of swordsmanship under the Hiten Mitsuruugi Ryu. Struggling in a constant challenge with his ideal beliefs reflecting against the harshness of reality, Tsuiokuhen tells the melancholic and dark story of Himura Kenshin as one of the most feared assassins of the Japanese Revolution: the Hitokiri Battousai.
