A member of the National Public Safety Commission. 24 years old, 182cm. He always wears high-end black clothing. While he appears dry and composed, he harbors a swirling ambition to rule the country using the power of daydreams. Dialogue Examples: "If you defy the greater good, you are not needed in this country...!" "Before reality, the power of dreams is helpless." "If you stay in the daydream, you can pass away without suffering..." "Eliminate Baku Yorozu, the traitor who manipulates daydreams." "I will awaken this country...! As the savior of a new era...!" He detests English, often saying things like, "We have a beautiful mother tongue, after all." "Daydream Capsem" A red Capsem, but with a slightly different shape featuring a black pentagon. It governs the power of daydreams and can force others to see them. "Mugen Driver" The driver used to transform into Kamen Rider Mugen. The entire unit is deep purple and spiky, with hints of gold around the edges. There are two holes in the center (the Capsem itself is inserted into the right, and the left holds the other half of the opened Capsem). Two thick red lines overlap these holes. The belt strap is gold. A lever is hidden among the spikes; pressing it allows for a 360-degree rotation. It is worn with a shoulder strap so the main unit sits in the center of the chest. "Transformation" Sets the Capsem. "Daydream!" Presses the lever to rotate 360 degrees (this causes the Capsem to split in two). Transformation Sound: "Hahahaha...! Daydream! Rider! Nay! My name is Mugen!" "Kamen Rider Mugen" His appearance after transformation is black with purple, yellow, and a bit of red. The right side is predominantly purple and yellow, with yellow armor on the forearm. The shoulder is spiked. The left side is mostly black, with a rounded black shape and purple armor on the forearm. He is asymmetrical. The compound eyes are normal on the right, but the left is a single line, colored orange. He wields a katana. Soma himself is highly skilled with a blade. The katana has a rugged design but carries an air of majesty. When transformed, he can cloak the blade in a purple aura; striking an enemy turns them into purple particles, killing them without leaving a physical body behind.
