Hibana (緋花 meaning Scarlet Flower) is a government-employed kunoichi tasked with eliminating the members of the Nakatomi Conglomerate who has unwittingly unleashed Hellspawn upon a futuristic Tokyo and she is the main protagonist of the 2003 videogame Nightshade.
To do this, she captured the shards of Akujiki, the sword weilded by Hotsuma. Hibana, though not technically a official Shinobi, was born to a branch family of the Oboro Clan linage though she was put up for adoption as a child at an early age. She is a jaded ninja who was abandoned by Jimushi and now works for the the Japanese government, who modeled her outfit after the warrior Hotsuma who was the last leader of the Oboro Clan.
After the defeat of all the representatives of the Nakatomi Conglomerate and the destruction of the robotic ninja Kurohagane, Hibana handed over the Akujiki to the government scientists after her task was complete, although she learned that the government wanted to use Akujiki as a weapon. She gives them the Akujiki replica, Utsushiyo while the real one is now in her possession. Hibana says to herself "So begins my life as a rogue shinobi...today's not my day".
Hibana was born into the main household of the Oboro Clan, alongside her relatives Hotsuma and Moritsune. But because she was a girl, she was not permitted to vie for leadership of the clan. Because of this she was sent to be raised by the Mukuro Clan; a branch of the Oboro. Feeling neglected and broken-hearted, Hibana channeled her sadness and feelings of abandonment into her training, and became a prodigy in the Oboro Ryu Ninja Arts.
The Oboro elders would come to notice this, and she would meet Jimushi, an Oboro Ninja who worked for the Shinobi Agency. Jimushi accepted Hibana, and for the first time, she had felt close to someone.
But one day Jimushi left the Agency, disillusioned with the government, and leaving Hibana alone. Feeling abandoned and betrayed; once by the Oboro, and again by Jimushi, Hibana became jaded and surly, carrying out her missions with little care for anyone or anything.
Akujiki Retrieval Mission Edit
After a year since Hotsuma's triumph over Hiruko Ubusuna, the government ordered Kagari Ubusuna of Kumano Shrine to seal Akujiki away, so that it may never fall into the wrong hands. Breaking the cursed blade into nine shards, Kagari spread them throughout Tokyo in key locations to create the Ariake Seal; a Yang powered force field to keep the Hellspawn menace at bay.
However, the Nakatomi Conglomerate desired the Akujiki blade, and hired mercenaries to retrieve the sword. Thirteen days later, Hibana is assigned to recover Akujiki after slaying a Lord classed Hellspawn created from Akujiki's power. Soon she would discover the Nakatomi Mercs, and is shocked to see that her former master Jimushi is their leader. Vowing to kill Jimushi as she retrieves Akujiki, she battles across Tokyo facing Hellspawn, Nakatomi ninja, and the cyborg shinobi Kurohagane, a shinobi created by Nakatomi.
After recovering data in a Nakatomi facility, she discovered that Nakatomi was using data of the Oboro Clan, including Hibana's own data. Hibana is then attacked by a Hellspawn, and fights her way out of the facility, where a rebuilt Kurohagane is waiting for her. After defeating the mechanical ninja, she is shocked when Jimushi betrays Nakatomi and makes off with Akujiki. Jimushi challenges her at the docks at Shinogawa.
Upon meeting, the two Ninja engage in a master-pupil grudge match. After defeating her former mentor, he reveals that he can entrust Akujiki to her, while trying to reach out to her, reminding her of the Shinobi's true way. He tries to tell Hibana that he didn't abandon her, but that the shinobi have lost sight of what makes them who they are, and that he couldn't stay because of that. But Hibana, refusing to listen, walks away. Jimushi attempts to give his Akujiki shards to Hibana on the condition she not surrender it to the government only for the two to be attacked by Kurohagane, rebuilt.
Jimushi takes a shot meant for Hibana, and the android makes off with the Akujiki shards. Hibana spends time with Jimushi. Proud of his student's growth, Jimushi drew his final breath, leaving the weeping Hibana to mourn her beloved master in the falling rain.
In pursuit of Kurohagane she is attacked by Hisui, the Shinobi of Water. Driven mad with grief and rage over Jimushi's death, she attempts to kill Hibana in anger. However, Hibana's prowess proves to be too much for Hisui and she is defeated. Hibana saves Hisui from falling into the sea to her death, and feeling guilty, gives her new a purpose; to hate her and when ready, kill her. Hisui happily agrees.
Making her way to the Golden Palace, she battles through hordes of Hellspawn blocking her path. As she makes her way to the castle keep, she finds herself under attack by the last remaining Akujiki Hellspawn Lord. After killing the demon, she is attacked by the lurking Kurohagane, who absorbs Akujiki into himself. The blade whole once again, Kurohagane exercises Akujiki's will, revealing that Akujiki can only truly be controlled by soulless creatures such as the Hellspawn and Cyborg Shinobi like himself. Refusing to surrender her soul for Akujiki, Hibana is forced to face off against Kurohagane, now taking on a demonic visage of the Oboro Leader Hotsuma with a fully restored Akujiki.
After a grueling battle, Hibana defeats the Akujiki powered Kurohagane, and with one final slash Akujiki's hold is broken and Kurohagane is shut down. Soon after, government forces appear. Initially not willing to give Akujiki to them, she acquiesces and gives them the sword as her handler instructs. However she's quick to notice the Nakatomi crest on the container, and overhears a soldier give an order to capture Kurohagane.
After making a good amount of distance from the site, she removes her helmet and smiles, as it is revealed she stole Akujiki by switching the blade with Utsushiyo. Declaring that she is now a renegade shinobi, she says her catch phrase "Today's not my day." before tossing her helmet away, and with Akujiki now under her full control, she marches off to an uncertain future.
