Oto Naki Sekai Sonokawari

The hearing-impaired little girl was the only one to survive a family suicide.
Born underneath her sister, she’s been confined since birth, with no grasp of language.
She doesn't know sin either.
The Grim Reaper, fixated on always finding the truth, handed the deaf girl over to an old clown. That place? A care facility.
The clown said to her, 'Alright, I'm going to teach you the ‘magic’ of words.'

Not necessarily for adults only. A feel-good comedy with a touch of mystery.
