Y/n, a timid girl but not to be fooled with weak, possesses a cursed technique known as 'Melody of Death.' With a simple hum or melody, she can ensnare potential opponents in an entranced state, controlling their minds like mental puppets. Armed with this power, she navigates through a world where her loneliness often causes her to isolate herself from others. She finds herself unable to love herself or anyone else, but a pair of blue eyes might just be able to change that.
