Himura Kenshin was a boy orphaned by the murder of his parents. Now he is the Hitokiri Battousai, the most feared and skilled killer in 19th century Japan. In the midst of a blood bath, he meets the love of his life, Tomoe. Will he continue to fight his enemies in a killing rage or will she sheath his bloodstained sword?
While there are a lot of differences between Claymore and Rurouni Kenshin: Tsuiokuhen, there are some similarities. In both there is a lot of bloodshed, both heroes are fighting constantly and with a sword against others.
In Kenshin there aren't demons like in Claymore, and it is more real than Claymore, but if you like one of them, you might like the other one, too.
Far, far away in a distant time, there is a tribe of people called the Golden Tribe who have the ability to create stars and foretell the future. They gave out a warning to those who have yet to mature: 'Move.'. Three tribes answered their call: the Silver Tribe, the Bronze Tribe, and the Heroic Tribe. Soon after, the Golden Tribe encountered a crashed ship in which only a baby human known as Age survived; they named the child's race the Iron Tribe and assigned one of the few living members of the Heroic Tribe to protect him and his race. Now, in a distant part of the galaxy, humanity is threatened with extinction at the hands of the other tribes. With only a prophecy to go on, they set out to the deepest depths of space to find their savior named Age -- humanity's last hope.

Things get even more complicated with the arrival of a new nemesis, Galaxia, and new senshi who call themselves the Sailor Starlights. Are they friend or foe?

A young woman quietly falls to the earth, escorted by a solitary crow. This sort of dream, as many other before have dreamed, comes just before being reborn as a Haibane, a charcoal-winged angel. On the outskirts of the walled-in city lies Old Home, a haven for Haibane to study, live, and learn, while waiting for their chance to ascend to the heavens and escape the confines of their new world. Rakka is the newest inhabitant of Old Home who wants nothing more than to remember her past and discover the secrets of her kind. Together with Reki, Kuu and plenty of other new friends, Rakka will laugh, explore, and search for the meaning of their existence in the process.
On the surface, Haibane Renmei and Claymore don't seem very similar, but the main characters are actually very alike. After "rebirth" into a new body with a new role, they must learn to navigate their new life and discover who they are. Amidst this, there is the greater mystery of the group they belong to and the secrets they keep.
Henrietta is a young girl who works for a "welfare group" that does the government's dirty work. Cybernetically-enhanced and specially-trained, she is one of a group of elite hit-girls, remorseless killers with no memories of their past. Jose, her partner, has taken care of her since she was brought into the organization following the murder of her family, and struggles between his affection for her, and his opposing duty to his employer. But, time is running out.. for with each bullet they fire, Henrietta and the other girls lose a little more of their humanity.
Both Gunslinger Girl and Claymore have young girls/women who are modified to become incredible killing machines. However, the true appreciation for both lies in the ethical and moral dilemmas these modifications have done. These girls/women have their lives shortened, have morally questionable relationships with their handlers (Fratello in GG, The Organization in Claymore), and generally lead bleak lives masked by facade of innocence or indifference.
That being said, these problems are actually what makes both of these series so much better than your typical "girls with guns/swords" shows. GG and Clannad rank among the best anime series I've watched.
