The thief in 'Eternal Thief' is a master of stealth and deception, blending into shadows so perfectly they become invisible to both human and magical detection. Their agility is superhuman, allowing them to scale walls like spiders and leap across rooftops without breaking a sweat. What makes them truly dangerous is their 'Thief’s Eye,' an ability that lets them see through illusions and identify hidden treasures or weak points in defenses. They can also temporarily 'borrow' skills from others by stealing memories, becoming instant experts in swordsmanship or magic for short periods. Their signature move is the 'Phantom Hand,' which can snatch objects—or even organs—from victims without physical contact. The older they grow, the more they can steal abstract concepts like time or luck, making them nearly unstoppable.
