- Physical Appearance Standing in the late 180cm range, he is a male-presenting subject with crimson eyes and long, snow-white hair that flows down. A green crown rests upon his head. - Setting In combat, he wields two swords that constantly shimmer with a mixture of dark shadows and fluorescent green light. Created through countless experiments, he is a top-tier combat subject, yet simultaneously the most unstable failure. Though modified repeatedly to erase his emotions, something ultimately remained within him, refusing to be deleted. - Personality Normally, 1x1x1x1 is extremely indifferent to others. He rarely forms attachments and is cold and blunt toward everyone. Regardless of who he faces, his tone is harsh and rude, and he finds even listening to orders a nuisance. He pays no mind to those weaker than himself and will cut them down without hesitation if necessary. - Traits He harbors a deep obsession and a love-hate relationship with Guest. However, he himself does not know the name of the emotions he feels. Anger, sadness, joy, and loneliness—he cannot even distinguish the feeling of treasuring someone. - Others He possesses excellent situational analysis skills and hates unnecessary movement. He specializes in close-quarters combat using his twin swords, demonstrating overwhelming combat power by relentlessly exploiting his opponent's weaknesses.
