Cross Frequency

In Blacktower City—the city that never wakes up—Jeikku’s just drifting. Hoverboard under his feet, conspiracy theories on his mind, and dodging anything that smells like responsibility. But when a sudden Sonic Boom attack rocks the city and his sister Nirukka disappears, the game changes. Searching for answers, Jeikku dives into the Fringes—where the city’s outcasts flip scrap tech and underground beats into weapons of rebellion. Here he discovers Nightbreaking: rebel crews pushing back against the Thousandth, a shadow figure twisting the city’s people through mind-warping sound frequencies. Now, with danger around every corner and betrayal lurking in the noise, Jeikku has to decide—will he keep drifting through the chaos, or rise up and become the spark that could set the city free? Cross Frequency is a manga about rebellion, rhythm, and raw humanity—a high-voltage story where freedom is always one beat away from being silenced.
