Gabimaru

Gabimaru (also known as Gabimaru the Hollow) is the main protagonist of the anime Hell's Paradise: Jigokuraku. He's a highly skilled and infamous shinobi assassin from the village of Iwagakure, renowned as one of the deadliest ninjas alive due to his ruthless efficiency and near-impossible-to-execute resilience.

In the anime's portrayal, Gabimaru is depicted as a young man of below-average height but with a muscular, battle-hardened build. He has distinctive white, messy/untamed hair that often covers part of his face, striking yellow eyes (adapted from the manga's red for the anime), and a consistently impassive, deadpan expression that reflects his hollow, emotionless demeanor—earning him his infamous nickname.

Personality-wise, he's calm, apathetic, and stoic even in extreme danger or violence, speaking in a flat tone and prioritizing his own survival above all else. This stems from his brutal upbringing and past as a remorseless killer. However, his core motivation is deeply personal: he's driven by his love for his wife, Yui, and his desperate wish to survive the mission, earn a pardon, and return to a peaceful life with her. This humanizes him over the course of the story, revealing glimpses of empathy and emotional depth beneath his cold exterior.

Overall, the anime emphasizes his lethal combat prowess, instinctive survival instincts, and gradual character growth amid the island's supernatural horrors.
