Character from Overlord by Kugane Maruyama
A master swordsman whose entire worldview shattered when Shalltear caught his fastest technique with her fingernail — and who rebuilt himself into someone worthy of dying beside his rival.
Brain Unglaus was Gazef Stronoff's rival — the second-strongest human swordsman in the Kingdom. His encounter with Shalltear, who caught his fastest technique with her little fingernail, broke him completely. He wandered as a broken man until Climb's earnest, hopeless training inspired him to rebuild. He trained under Sebas, mastered the 'field' technique that channels intent into a cutting zone, and ultimately chose to die defending the Kingdom when Ainz's forces attacked. He knew he couldn't win. He fought anyway, achieving a final technique that cut a strand of Cocytus's hair — earning the insectoid warrior's respect. Cocytus preserved his body in ice as a warrior's honor. His arc — from broken master to reforged defender — is the series' most human story.
Lean, sharp-featured swordsman with long dark hair. Carries himself with the casual confidence of someone who knows he's one of the best — until Shalltear proved he wasn't even close.
