Occupation: Eimin Gutaika is an elite criminal and highly skilled assassin and saboteurs who prefers stealth and trickery to the open and honorable combat engaged in by others. When conflicts arise that cannot be solved by legal means, the corporations, governments, wealthy individuals, and even organized crime will subcontract their dirty work to deniable specialists. Eimin Gutaika falls outside the structured corporate world.

Personality: Eimin Gutaika typically only shows tenderness to his panther, and is described by others as a ruthless assassin. He accepts the authority of his masters and would never betray them. He rarely talks and shows little interest in the others' exploits, often staying only until he can collect his fee, then leaving at the most inopportune moments. Eimin Gutaika has a troubled past, warning about "people who have killed their emotions", and encourages others not to do the same. Despite his cold and taciturn exterior, Eimin does develop a kinship with the Earth Special Forces, and he does oppose inhumane actions. In contrast with his disturbing appearance, he is very loyal.

From there, Eimin Gutaika became caught up in the Earth Special Forces' fight against evil. He would still come and go as he pleased, but he began to believe in their ideals.
