Nishiki

Kamen Rider Western Demon is one of the many Oni Kamen Riders in the fanfictional series Kamen Rider: Echo Demon.

Nishiki
He is a thief Oni who loves money; Nishiki is often caught in situations leading people to believe he is a criminal. He refuses to join the Oni group at first until tricked in believing there's buried treasure in the village they're saving. Though after learning it was a trick & leaving, he returns in the final battle.

Being a thief, Nishiki loves money & treasure. He is a very energetic man, which may sometimes lead to some of his hotheadedness.

Like some of the Oni Kamen Riders, Nishiki has a human form, though it's unknown if he also has a human name.

Demon Transformation Tuning Fork
Western Demon's transformation device. Nishiki taps this tuning fork & sets it in front of his face while it vibrates. He shouts out 'Western Demon' before the transformation begins.

Demon Attack Drum
A taiko buckle.

Sound Attack Triangle
Western Demon's personal weapon. This is a tri-sectional staff that is very effective for middle-ranged & short-ranged combat. The end components of the staff are long enough that when the two ends meet, the staff forms a triangle.
