Cruhteo
Count Cruhteo is of high status in Martian society and often discriminates against the people of Earth. Count Cruhteo shows a lot of hate towards Princess Asseylum's best friend, as Slaine was born on Earth. However, he holds great respect for Slaine's loyalty to the princess. He tries to dissuade Asseylum Vers Allusia from her goodwill visit to Earth, as shown in Princess of VERS. After the attempted assassination on the princess, he supported an invasion of Earth. He landed his Landing Castle in Tokyo, hoping to be the first to investigate the princess' apparent death. He was convinced by Sir Trillram to let him be the one to plant a flag on the location of the failed assassination as a symbolic gesture. In reality, Trillram wanted to cover up the fact that it was his faction who committed the assassination from Cruhteo. (Source: ALDNOAH.ZERO Wikia)
