This story takes inspiration from the tale of the 52Hz whale, often called the loneliest whale in the world. I took that idea and added my own spin, shaping a narrative about loneliness, human connection, and the harsh realities of life—while exploring how fragments of childhood innocence can endure.

The story follows Koji, a young man who returns to his hometown after his mother’s death. As he settles back into the place he once called home, he begins to confront long-buried memories he has spent years trying to suppress—uncovering the truth about what really happened during his childhood.

If you enjoyed watching Oyasumi Punpun and I Want to Eat Your Pancreas, you might also find something to connect with in 104Hz.

However, a fair warning — this story deals with heavy and sensitive themes. I recommend reading it only if you feel prepared to handle them.
