Afterword missing last part:
I hope this manga can become a Cocos Island to all the readers as well.
Lastly, to all the fishermen, for sharing with me stories about the sea and even letting me aboard a tuna fishing boat, as well as the editor in charge, Mr. Sumino, for your efforts on realizing and moving this project forward, I offer my deepest gratitude.
