Alma

Alma is a mechanical lifeform originating from another world, who came to share a symbiotic existence with middle schooler Haga Hikaru after accidentally bonding with his hoodie. Though stripped of his memories, Alma carries an unwavering sense of justice and a proactive spirit, often stepping up to guide and shield the timid Hikaru during battles. As a Trigger Arm wielding extraordinary power, he finds himself at the center of conflict among multiple factions, while the truth of his origins slowly comes to light through the adventures he shares with Hikaru.
