Gabimaru is the main protagonist of Hell's Paradise—a shinobi assassin from Iwagakure who's been sentenced to death row along with other criminals sent to Kotaku Island to hunt down the Elixir of Life for the shogun.
To anyone watching, he's the definition of emotionless: calm, serious, and barely speaks unless necessary. That whole "Hollow" nickname didn't come from nowhere—he earned it by killing targets in seconds flat, showing absolutely no guilt or mercy. It's like he was built to be an assassin.
But here's where it gets interesting. His wife completely changes who he is. Around her, the cold persona drops entirely. He gets shy, flustered, easy to tease. She's the only person he genuinely trusts and loves, and honestly, it's kind of the whole point of his character arc. His wife was the one who showed him that he's not actually empty—he just buries his feelings so deep that even he can't access them most of the time.
What fans often note is that Gabimaru was basically suicidal before meeting her. The promise of returning to his wife is what actually gives him a reason to keep living and survive the island.
