I got curious and translated the title of the OST ‘’ Yonaka Ni Kiku To Kowai ‘’
And that’s when all the piece came together.
Yonaka Ni Kiku To Kowai means something like:
‘’ I am scared when I hear it in the middle of the night. ‘’
The ‘’ I ‘’ here…. Is Shinsou.
Shinsou is scared when he hears ‘’it’’ in the middle of the night…
‘’ It ‘’ is all the noises you hear in the song. The laughing children, the whispers, the bloody screams… That’s what he hears everytime he tries to sleep. The voices from his past.. And because of them, he just cannot sleep. That’s where his bags comes from.
The humming in the background must be his mother’s lullaby. Because he wouldn’t be able to sleep at night, she would sing him to sleep. Her voice would cover the voices in his head….
