To Your Eternity Season 3 Episode 17: A Modern Wake-Up Call for Fushi’s Immortal Journey

If you’ve been following Fushi’s centuries-long quest to protect humanity from the shape-shifting Nokkers, you know this immortal being’s story is equal parts heart-wrenching and awe-inspiring. Season 3 Episode 17—titled “To Your Eternity Battle,” per the latest synopsis—finally lands Fushi in the modern era, and let’s just say the wait (even with that 3-week delay for the 2026 Winter Olympics) was totally worth it. Brain’s Base, the studio behind hits like A Silent Voice, brings their signature emotional depth to this episode, blending quiet character moments with the series’ classic existential weight.

First off, let’s talk about the vibe shift. After spreading his roots across the globe to wipe out Nokkers, Fushi’s been chilling in modern times—hanging with friends, enjoying peace, basically living the “normal” life he’s always craved. But as any To Your Eternity fan knows, peace never lasts. The episode opens with Fushi laughing over takeout with a group of teens, his human form relaxed and unguarded. It’s a jarring contrast to the war-torn landscapes we’re used to, and it works: you feel how much he’s grown to value these small, fleeting moments. One fan on MyAnimeList put it best: “Seeing Fushi order boba and argue about video games? I almost forgot he’s an immortal who’s seen civilizations rise and fall. It’s so human.”

Then the threat hits—and it’s not just Nokkers. The episode introduces a new antagonist: a shadowy organization that’s been tracking Fushi, convinced his immortality is a weapon to be controlled. Their first attack is sudden and brutal: a drone strike on Fushi’s apartment, forcing him to shift into a bird mid-explosion to escape. The animation here is chef’s kiss—Brain’s Base nails the fluidity of Fushi’s transformations, making each shift feel both instinctual and painful. A Reddit user raved, “That scene where he turns into a cat to dodge the debris? The way his fur stands on end, the panic in his eyes—you can tell he’s not just fighting for his life, but for the friends he’s finally let himself care about.”

What makes this episode stand out, though, is how it dives into Fushi’s identity crisis. For centuries, he’s defined himself as a protector—but in the modern world, protection looks different. When his friend Kana (a human teen he met at a café) gets caught in the crossfire, Fushi freezes. He’s used to sacrificing himself, but now he’s scared to lose someone he loves as a human, not just a guardian. A MyAnimeList review summed it up: “Fushi’s always been ‘the immortal,’ but here he’s just… Fushi. A guy who doesn’t want his friends to get hurt. That vulnerability hit me harder than any Nokker battle.”

The episode ends on a cliffhanger: Fushi’s forced to reveal his immortality to Kana after healing her gunshot wound. Her reaction? She doesn’t scream or run—she just says, “So that’s why you never get sick.” It’s a small moment, but it’s huge for Fushi. For the first time, someone sees his true self and doesn’t fear him. As one fan pointed out, “That line made me cry. Fushi’s spent so long hiding who he is, and now he’s got someone who accepts him. Finally.”

Sure, the 3-week delay was frustrating, but Episode 17 delivers on every level. It balances action with heart, asks big questions about what it means to be human (even when you’re not), and sets up a new arc that feels fresh but true to the series’ core. If you’re a fan of emotional storytelling with a side of existential dread, this episode is a must-watch. As one viewer put it, “To Your Eternity doesn’t just tell a story—it makes you feel it. And Episode 17? It’s the show at its best.”

So grab your snacks, tissues, and maybe a boba (Fushi would approve), and dive into this modern chapter of Fushi’s journey. You won’t regret it.
