|A Mars trilogy character|
|Affiliations||Reds, The underground|
|Ancestors||Hiroko Ai, John Boone|
 Early life
one of the earliest members of the Martian underground, he wandered a lot across Mars with the Coyote and embraced Red views. He had fit a stone eyetooth as a recognition sign for Reds. With Coyote, he was responsible for many sabotages against transnational infrastructure in the 2040s-2050s.
 Radicalization and death
He was said to be frustrated at the fact that because of the longevity treatment the issei kept the reins of power and did not naturally cede it to the next generation. He became a Marsfirst leader.
He later became even more radicalized and a leader of the Kakaze. He was killed with many Kakaze and long-time friend Dao while trying to take the elevator cable from the UNTA by force at the second revolution.
His name means "fire star" in Japanese; this is also the Japanese name for the planet Mars. There is a Martian valley with the same name (Kasei Valles).
