Bianchi is a character from the futuristic anime series Nobunaga The Fool. The full name associated with this character is Bianchi Tepes. Bianchi is a resident of the Western Planet and is identified as one half of a pair of twins, with Nell being the sister. The primary reason for the twins journey to the Eastern Planet is to observe and keep watch over the character Caesar.

In terms of appearance, Bianchi is depicted as a youthful individual with blonde or yellow hair that falls to the neck, paired with green eyes. The character has pointed ears resembling those of an elf and is often seen wearing a vest, shorts, knee-high socks, a cape, and boots, sometimes carrying a bow. While some sources describe Bianchi as having a strong personality, other references list the character as male. Despite a seemingly childlike or innocent appearance, Bianchi undergoes a dramatic transformation in the midst of battle, changing into a demon who harbors a love for war. This duality defines Bianchi's role in the narrative, shifting from a quiet observer to a ferocious combatant when conflict arises. The character does not have a significant amount of documented backstory or a detailed character arc beyond these fundamental traits of observation and hidden ferocity, with abilities primarily focused on this combat-oriented transformation.
