Alright! here is my masterpiece summary:Ethan is an ordinary teenager 17years old reincarnated to a fantasy world with unique abilities — to channel the powers of legendary anime characters in combat. But in a world teetering on the edge of ruin, raw strength alone is not enough. The Demon King has seized the throne, plunging the kingdom into chaos, and humanity now struggles under the rule of tyrannical races that see them as nothing more than pawns or prey.

The path to salvation is neither simple nor merciful. Ethan’s journey will test not just his power, but his will to endure. Along the way, he will forge alliances with those who share his vision, warriors hardened by war and betrayal. Yet even with their combined strength, victory is uncertain. The world is filled with monsters—both literal and human—each with their own ambitions, and not all battles can be won by brute force.

As the war for humanity’s survival unfolds, Ethan must navigate the fine line between heroism and destruction. The strongest abilities come with a cost, and not every enemy can be felled by power alone. Some will have to be outwitted, others bargained with, and some may force him to make choices that will haunt him forever. In the end, the question is not whether he can defeat the Demon King—but whether he can do so without losing himself in the process.
