First appearance: Chapter 588
Saint Jalmack is a World Noble introduced ten years before the series began.
Though initially hidden in shadows, Jalmack's hairstyle resembles that of the Roswald family, with two bulb-like protrusions. He also has a prominent, wide chin.
Like all other World Nobles, Jalmack wears a thick suit decorated with medal-like knobs on the front. However, since he was not at Sabaody Archipelago, he cannot wear one of the resin bubbles as a helmet, as these bubbles would pop outside of that area. Instead, he wears a rectangular helmet to avoid breathing the same air as commoners.
