Oda Nobunaga

Nobunaga is a powerful leader in JAPAN. He possesses one of the pieces of the sealed demon Zabieru, which turns him into a demon.

In the Kichikuou Rance alternate universe, he unified JAPAN under his rule sometime during LP0004.

In Sengoku Rance, he is the most influential warlord of JAPAN.

The beauty of his daughter, Kouhime, is known throughout the world.

Appears in: Kichikuou Rance, Sengoku Rance

Note: His character design in Sengoku Rance looks drastically different from that of Kichikuou Rance. About the only commonality is the existence of the monkey (who ALSO looks drastically) on his shoulder.

Trivia
The famous Oda Nobunaga in Japanese history is known for his cruelty. That might be the inspiration of making the Nobunaga in this world a Demon.
