He gains a cheat ability—enhanced cellular activity.Coincidentally, just before the Second Shinobi War, he participates in a Jonin meeting where he supports Tsunade's proposal ahead of Dan Kato, marking his first encounter with her.From then on, he launches an intense pursuit, winning her heart during the war.Tsunade: “Kawakaze, why do I keep losing to you?”Kawakaze Hatake: “Because I’d like to live a few more years...”Kakashi: “My uncle is amazing, I’m his biggest fan!”Kawakaze Hatake: “Keep it low-key, keep it low-key.”

He crossed over to a new world where humans have magical power. They are called warriors. They use their power to kill the monsters that appear out of nowhere. Dragons, Dungeons, and Magic users are pretty common in this world. If you want to live in peace, you need to have that power. You can also become a powerful clearing dungeon.

In this dangerous world, he has a system that can help him grow stronger. But he didn't want to be a high-profile warrior who attracts much powerhouse attention or become a lab rat. He wants to be Low-profile and grow strong using his system.

Just like how everyone adored heroes in their childhood, a certain young man adored those powers hidden in shadows. After hiding his strength and living the mediocre life of a mob character by day while undergoing frenzied training by night, he finally reincarnates into a different world and gains ultimate power. The young man who is only playing at being a power in the shadows, his misunderstanding subordinates, and a giant organization in the shadows that gets trampled…. This is the story of a young boy who had adored powers in shadows possibly eventually reigning over the world of shadows in another world.

When Ryujin wakes up in the video game he use to play, Espers of the World, he quickly realizes something terrifying: this isn’t a game anymore—it’s reality.Stripped of his identity and renamed Kaidren, he must now survive as a low-profile orphan with a mysterious past and a future controlled only by power. The world around him mirrors the game’s setting, yet the rules are no longer bound by code. The television works. The phone updates in real time. Events that never occurred in the original storyline unfold before his eyes.The NPCs? They’re real people now—with real emotions, real consequences, and real power.As Kaidren struggles to adapt, he’s haunted by memories of a trauma-stricken life and an overwhelming detachment from emotion.But the deeper he explores this so-called game world, the clearer it becomes—this reality is unpredictable, unscripted, and far more dangerous than he ever imagined. And to stay alive, he’ll have to confront what it means to be human... and what it means to be powerful.Because in this world, the line between player and pawn no longer exists.
