How Old Is Subaru Natsuki, The 17-Year-Old From Re:Zero

Welcome to our flagship hub, where we dive deep into the fascinating world of Subaru Natsuki! You might have stumbled across this page wondering how old Subaru Natsuki is in Code Geass. It's a common query, and we're here to clear up a crucial detail right away: while Subaru Natsuki is indeed a hugely popular character, he's actually the protagonist of the acclaimed series Re:Zero – Starting Life in Another World, not Code Geass. Code Geass features its own iconic hero, Lelouch Lamperouge.
Now that we've set the record straight, let's turn our full attention to the 17-year-old shut-in who found himself inexplicably pulled into a dangerous fantasy world, forever changing his understanding of life, death, and what it truly means to grow up.

Unraveling Subaru Natsuki's Age: A Re:Zero Deep Dive

Physically, Subaru Natsuki is a 17-year-old Japanese hikikomori when he first finds himself transported to a fantastical new realm. But as any Re:Zero fan knows, his journey is far from ordinary, and the concept of "age" for Subaru becomes far more complex than a simple number. His experiences challenge traditional notions of maturity, identity, and the wisdom gained through adversity.
This discrepancy between his chronological age and his profound experiences is a core theme of his character. If you're curious to understand how his unique journey shapes his internal clock, you'll find an insightful discussion in our guide on .

The Core Identity: 17 Years Old, Forever Changing

When Subaru is plucked from his mundane life, he's just a regular teenager—a bit aimless, but with an underlying good heart. His 17 years prior to arriving in the Emilia camp might have been uneventful, but his time in the new world forces an accelerated evolution. He grapples with finding his identity, cultivating emotional maturity, and shouldering responsibilities far beyond what any typical 17-year-old could imagine. He remains physically 17, but his soul ages with every agonizing setback and hard-won victory.

Return by Death: The Power That Shapes His Soul

The most defining aspect of Subaru's existence in this new world is the ability he dubs "Return by Death" (死に戻り, Shinimodori). This terrifying power allows him to rewind time to a specific checkpoint after he dies, retaining all his memories from previous timelines. It's a brutal gift, forcing him to endure countless deaths and trauma, yet it's also the key to saving those he cares about. The catch? He cannot disclose this ability to anyone; attempts to do so result in a crushing pain in his chest, an invisible hand silencing him, and even threatening the lives of those nearby. This power also inadvertently makes him emit the "Witch's Scent of Envy," attracting dangerous mabeasts.
Understanding the full scope of this curse-like ability is crucial to grasping Subaru's character. For a complete breakdown of its mechanics and horrifying implications, explore our deep dive into .
