Himiko is the shaman queen of Yamataikoku in ancient Japan who was briefly mentioned in Records of Three Kingdoms as having contact with Wei. Though there are few written records regarding the nature of her rule, oral legends and archaeological evidence proves that she existed.
Prior to her playable Warriors Orochi appearance, a Samurai Warriors item was named after her. She can be unlocked in the second game by completing Shu's story. The fifth anniversary PlayStation 3 version of Dynasty Warriors: Online allows players to acquire Himiko's ribbon as an in-game accessory for female avatars.
Sometime after Orochi's defeat, Da Ji finds Himiko in the new, parallel world. It is unclear how they met or when, but the young girl admires Da Ji and follows her where ever she goes. When the other forces begin to pursue Da Ji and the Orochi forces, the ladies flee from their pursuers to join Kiyomori. Himiko sometimes stays behind to help her friend by summoning magical spells to disrupt the enemy. Though Da Ji is eventually caught, Himiko reaches her destination and the divine energy within her blood is used in a ritual to resurrect Orochi. In Wei's scenario, she continues to fight for Orochi's army but falls in combat.
She is given three dream stages in Musou OROCHI Z. In the first dream stage at He Fei, she mainly tags along with Da Ji and Benkei. Though unsure of the giant's use to them, she calls upon him again to help rescue Da Ji at Mikatagahara from the Wei and Wu armies. Himiko joins with San Zang and Sun Wukong in their journey west, passing through Nanzhong. She agrees with doing good deeds and criticizes Sun Wukong's slurs. Her personal deed in the battle is protecting the stranded maids by summoning an army of phantom soldiers to protect them from Meng Huo.
Himiko remains Da Ji's steadfast companion in the third installment who exerts herself to protect Da Ji from being taken captive throughout the timelines. She frequently tries to sacrifice herself for Da Ji's safety. The girl gains some respect for the coalition when Kai allows her escape at Nanzhong. When her friend is being hunted by Nezha at Sekigahara, Himiko panics during her escape and runs to Hanbei's faction for help. While Himiko trusts the coalition after they save her friend, she is unaware that she is technically the coalition's hostage for preventing Da Ji's betrayal. Later she entertains herself by helping the search for Guan Suo in a past battle at Mt. Tinlao.
In the downloadable scenario, "Demons vs Mystics", Himiko fights several mystics to protect Orochi at Koshi Castle.
During the events of Ultimate, Himiko and Da Ji manage to escape from the Coalition after the Hydra's demise and resume their travels alongside Sun Wukong. With the Coalition hot in their trail, they are lured by an unknown voice to Hinokawa where they find a mysterious stone that creates doppelgangers of people they've encountered in battle. This discovery leads to their meeting with Tamamo who helps them cause rifts between the various factions. After Tamamo's defeat, Himiko is last seen accompanying Da Ji after leaving behind a piece of the Divine Mirror.
Suffering from amnesia in Warriors Orochi 4, Himiko was transported back to the new world to be attacked by Ares' army. While she was able to evade the god's wrath, she misinterprets the Coalition to be of the same party and lashes out on them when they attempt to speak to her at Jing Province. Da Ji soon arrives and takes Himiko away.
She continues to support the demon army throughout their fights against the Coalition. After Orochi X and Orochi are slain, Himiko and the rest of the Demon army decide to join the Coalition to prevent themselves from being destroyed by Odin's plans for Yggdrasil.
Himiko retains her role within the demon army in Ultimate and constantly harasses the Coalition. When the Coalition launches various attacks against various outposts to weaken Yggdrasil's defenses, Himiko is charged with defending Nagashino from Shingen, Zhong Hui and Zhou Tai's assault force. Despite her many preparation prior to the battle, the commanders see through her attempts to trick them and force her to flee back to the rest of the Demon army.
Similarly to the main story, she joins the Coalition after Orochi X and Orochi's final defeat at Kanegasaki in order to stop Odin's plans for destroying the world.
In the alternate scenario that Perseus is revived and exposes Hades' deception, Himiko and the rest of the demon army arrive to reinforce the Mystics at Changshan as they create a barrier to restore Kaguya's time-traveling abilities with Gaia's memory of the Earth.
In the side stages, she and the rest of the demon army under the Coalition defend Osaka Castle from Odin's army. After the battle, she pranks Yoshitsune by misinforming him of an enemy attack.
And she is reprised by G.K. Bowes in the English dub and Sayaka Maeda in the Japanese dub.
