Physical Appearance

Hoto has the appearance of a small robotic humanoid boy with faded purple hair and dim purple eyes. He does not seem to be effected by the ruin but he has two lines that run from the opposite side of both of his eyes, though this is more then likely a part of his design. He wears a dark jacket over a light purple shirt with a multi color collar.


Hoto was a kind Robot who believed that the world belonged to everyone but still had a firm belief in protecting Luna's secrets, just like her siblings. He was very kind towards Casshern, Ringo, Ohji and Lyuze though they were strangers never and even entrusted them with Luna's secret.[1]

Casshern Sins

Hoto was built by Luna's creator as a project to mimic Luna's abilities. Hoto along with, Hoti and Holter were failed subjects, leaving Luna as the only Sun. When she was murdered by Casshern, the Ruin began and the creator died leaving the three to guard Luna's secrets.[1]

A mysterious group of travelers arrived on day during one of Hoto's strolls with his siblings. They met with then and talked about their past with Luna, referring to her as their sister and their mother. They left after Holtor began to weep due to his frail body. On their return home they were confronted by someone who reminded them of Luna, Leda. But too soon they realized her evil obsession with finding Luna but was saved by the travelers before she could get any information about Luna. After Leda was forced to leave, Holtor chose Ringo as the chosen traveler and Hoti and Hoto went to sleep, in order to unlock Luna's Secrets within Holtor.[1]
