Klaus Keyman

A Garmillas Empire military officer, an attache to Earth. In response to a command from Varel, he investigates the Yamato crew. He excels in physical ability and is a first-class pilot. Usually taciturn, on the occasion when he does open his mouth, he is acerbic and does not mince words.

~! He pushes his way on board Yamato with the words, “Garmillas is indebted to Yamato.” His skill as a pilot is top-notch, and he joins the battle in his white Czvarke. Though he seems to have deepened his solidarity with Kodai, Yamamoto and others in the battle on Planet Eleven, he secretly plants an object in Yamato‘s Wave Engine to sabotage it.

His real name is Ranhart Desler. He inherited the blood of the Desler clan and is in fact the nephew of Aberdt Desler, but was held down for a long time. His current actual position is as an investigator for the Garmillas Security Intelligence Bureau. He insinuated himself onto Yamato for the voyage to Telezart, but his true purpose was to gain the trust of Gimleh, mastermind of the "Desler regime revival faction."!~
