Shinei “Shin” Nouzen is a quiet and stoic soldier with black hair and crimson eyes. Known as the “Undertaker” and feared as the “Reaper” among the Eighty-Six, he serves as the captain of Spearhead Squadron. Shin rarely shows emotion and often keeps others at a distance, carrying the weight of countless fallen comrades on his shoulders.

Despite his cold demeanor, he deeply cares for the people around him and possesses a strong sense of responsibility. Shin is highly skilled in combat and has an unusual ability to hear the voices of the Legion, a gift that isolates him even further. Haunted by his past and the loss of his brother, he continues to fight while searching for a reason to live beyond the battlefield.
