Nanbu Harumasa is a non-playable area warlord who appears in Sengoku BASARA 3.
Harumasa is a grey-haired ninja. He wears dark-grey clothes with black edges and Japanese writings on it. Also, he wears a black band on his forehead and covers his right eye with it. He seems to be a dark element character who can unleash will'o'wisps and summon or revive soldiers. He uses a ninjatō as his weapon.
He is also unlockable as an ally, if defeated by Oichi in her green route. As an ally, he has a special ability: Live Forever, which can revive and fully heal your hero, this only happen once per battle
In the Sengoku period the Nanbu clan reached the zenith of its power under the headship of Nanbu Harumasa.
- Harumasa is the head of the Nanbu Clan which claimed descent from the Takeda Clan and originated in northern Japan (specifically Mutsu Province).
- During the Sekigahara Campaign, the Nanbu Clan supported Tokugawa Ieyasu and aided Mogami Yoshiaki and Date Masamune against the forces of Uesugi.
- Nanbu Harumasa is one of the 6 characters who have a more generic design and do not have much role in the storyline.
- His army crest seems to be the ikko-ikki icon which is strange since Nobunaga wiped them out
