Gabimaru

Saku (朔), often referred to as the mononym Gabimaru (Japanese: 画眉丸), is a fictional character and the main protagonist of the manga series Hell's Paradise: Jigokuraku, written and illustrated by Yuji Kaku. During Gabimaru's time as a shinobi in the Iwagakure village, he was known as the strongest person under the inherited title, "Gabimaru the Hollow". When he plans to quit, his execution is orchestrated by the village chief. The shogunate later recruits death row convicts to compete in acquiring the elixir of life from the Shinsenkyō island in exchange for a pardon for their past crimes.

Kaku created Gabimaru as a married character, with the mindset that he needed a strong and immediate motivation for his main character to fight to survive, making his wife his core driving force. In the Hell's Paradise anime adaptation, he is voiced by Chiaki Kobayashi in Japanese and Alejandro Saab in English. The character received generally positive acclaim from critics for his role in Hell's Paradise, for his character growth and his role as an anti-hero in his backstory.
