As a surviving remnant of the Davy Clan, Dawn had originally only wanted to set sail, figure out what was going on with his body, grow stronger, and avenge his family.

But he unexpectedly came across the Dark-Dark Fruit-one that should have belonged to his clansmen. As the old saying goes, 'If Heaven grants it and you refuse, you will suffer for it.' He decisively ate it.

"Sorry, Teach. You can't handle this fruit."

(P.S. The pacing is somewhat slow, but the author will release chapters in bulk daily. The first 100 chapters are slow-paced.)
