Eclipse Frequency

After the eclipse, the world is ruled by frequencies. 432Hz - free resonance. 440Hz - control signal. Sixteen-year-old Rin wakes up. Her eyes are amber, and her power is a "broadcast" tuner - allowing ordinary people to perceive frequencies. Shangcheng wants to put her in the calibration room and imprison her forever. She ran away. Then she discovered that the former civilization left behind seven "global frequency controllers" distributed in New York, Paris, Tokyo, Sydney, Rio, Cairo... The 440Hz signal is activating them. Once activated, all human beings will be brainwashed and turned into "efficient but emotionless" tools. Rin and her team - Hui (sensory type), Po (mechanic), Che (healing type) - must destroy all controllers. Six people, seven cities, a frequency war. Frequency will not disappear. It just... Finds an exit.
