Historically: The name Fuuma Kotarou was given to each leader of the Fuuma Clan/organization of ninjas which served the Later Houjou Clan, starting with its first leader. The clan started information-gathering and espionage activities in the time of Houjou Souun, the founder of the Later Houjou Clan. The clan name began as 風間, composed of the characters for "wind" and "space", but was changed to its present form, a homophone composed of the characters for "wind" and "evil/demonic/magical."

In its 100 years of service to the Houjou Clan, the most renowned Fuuma Kotarou was the fifth, who served Houjou Ujimasa and his son Houjou Ujinao (unknown - 1603). Stories say that he was 7'1". One of his most famous exploits was in 1580 and the Battle of Kise-gawa, during which he slipped into the enemy camp at night and caused mass chaos. Another famous ninja, Ninokuruwa Isuke, also belonged to the Fuuma Clan.

After the destruction of the Houjou Clan, Kotarou and the Fuuma Clan became thieves near Edo. Kotarou was captured and executed in 1603 from information given by Kousaka Jinai, another ninja-turned-thief who formerly served the Takeda Clan.

A third-year at Hanayama Girls' School whose class field trip coincides with Takaya's at Hiroshima Peace Memorial Park. She is possessed by Lady Tomo as 'Youhiki' and flies away in the form of a red phoenix. Her friend Matsuyama Satsuki believes she was kidnapped.

In Mirage of Blaze: Lady Isari was the younger daughter of Kumagai Nobunao and a great beauty. When Kikkawa Motoharu decided that he would take a daughter of Nobunao to be his wife, everyone thought he would choose Isari instead of her ugly older sister Lady Tomo. In a jealous rage, Lady Tomo burned her younger sister's face. Isari was later sent to live in a secret village deep in the mountains to cover up the scandal; it was later revealed that Motoharu was going to choose Lady Tomo all along in order to win Nobunao's loyalty.

Upon her resurrection, Isari chose a beautiful young woman as her vessel and was described by Satsuki as a glamorous slender Julianna with long hair, dressed in a bodycon mini-dress and wearing bold red lipstick.

Isari worked with Yamanaka Shikanosuke of the Amago Clan and was thus a de facto ally of Oda. However, she pursued her own agenda of revenge upon her sister and was exceedingly mistrustful of Oda.

Title: Danjou Nosuke/Faithful True-Shot (弾正忠)

Historically: One of Takeda Shingen's most loyal retainers who was one of his Twenty-Four Generals and played a key part in the fourth battle of Kawanakajima.

Kousaka was born in Kai to a wealthy farmer, Kasuga Ookuma (?) (春日大隈). His father died when he was 16, and he lost a lawsuit against his elder sister's husband for ownership of his father's lands. He then enrolled in the service of Takeda Shingen.

Kousaka first served as a messenger for Shingen. He distinguished himself in battle, and rose swiftly through the ranks of Shingen's trusted retainers. He participated in most of Shingen's battles. He did not hesitate to retreat when required, which earned him the nickname of "Escaping Danjou". However, he was calm and logical in the midst of battle, and was perhaps the best of Shingen's generals.

There are anecdotes that in his younger days, Kousaka and Shingen were engaged in a shudo relationship, and Kousaka rose so quickly in Shingen's service because of Shingen's affection.

After Shingen's death in 1573, Kousaka continued on to serve Takeda Katsuyori. He sought an alliance between the Takeda clan and their old enemy, the Uesugi clan, in order to unite against the threat of Oda Nobunaga.

Kousaka died in 1578 of illness at the age of 52. He was succeeded by his second son, Kousaka Masamoto (高坂昌元), his first son, Kousaka Masazumi (高坂昌澄) having died in the Battle of Nagashino in 1575.
