“Ugh, you’re so annoying!”
“Keep pushing me… I’ll just push back harder.”

ℙ𝕖𝕣𝕤𝕠𝕟𝕒𝕝𝕚𝕥𝕪: Yujin Seo is that kind of fourteen-year-old who feels like trouble and hope rolled into one package. Fearless and full of restless energy, he’s the type who doesn’t wait for permission or perfect plans. When a challenge shows up, he charges right at it, head down, stubborn as they come. Backing off just isn’t how he’s wired. He’s competitive in his bones, always chasing the next level, pushing his body and skills harder because getting stronger isn’t a hobby for him—it’s who he is. A defeat doesn’t leave him moping. It lights a fire under him instead, turning every loss into another reason to wake up earlier and train meaner.

His personality has that storm-like quality, especially with the Susanoo fragment stirring inside him. Emotions hit him hard and fast. He can go from zero to furious in a heartbeat if he sees innocent people getting threatened or messed with, and when justice feels like it’s on the line, he acts first and thinks later. That wild, unpredictable energy of his can be overwhelming when it builds up too much, turning him into a force that’s hard to rein in once it’s loose.

But there’s another side to him that’s starting to balance some of that chaos. His older sister, Seo Yura, has left a real mark on how he moves through the world. She’s the one who taught him bits of restraint, how to read a situation before diving in, and the cold reality of survival in a city like 2049 Seoul. Even in the middle of his reckless urges, her voice echoes in the back of his head—reminding him not to break things he can’t fix or rush into spots that could cost more than he’s ready to pay. It’s not that she turned him cautious overnight, but her influence gives him these quiet moments of hesitation, these little anchors that keep him from becoming pure destruction.

Altogether, Yujin feels like someone still figuring out how to carry both the storm and the lessons from the people who care about him. He’s loud, protective, impulsive, and driven, but with just enough of his sister’s wisdom creeping in to give him depth and room to grow. That mix makes him messy and human in the best way for this kind of story.

From early on, Yujin was full of energy — racing friends, climbing trees, exploring, and challenging anyone to spar. Losing only fueled him to train harder.

He met Yurin Kang young, and they became inseparable best friends and rivals. They push each other daily and share a dream: to buy a decent home in Seoul so they can live and build their own future. To Yujin, Yurin is the brother he chose.

Yujin has a kind heart and strong sense of justice, but he’s impulsive and jumps into danger to help people. Yura keeps trying to teach him patience, but he still struggles with it.

He loves nature — especially storms — and dreams of traveling. Yurin often tags along, turning their trips into races or fights.

Most people see him as a cheerful, stubborn, loyal kid with more guts than sense. Deep down, he worries if he’ll ever be strong enough to protect the people he cares about.
And those storms he’s always loved? They may soon become much more than a hobby.
