One Piece: Shadow Guardian

Not dark or preachy.

The story currently follows an ordinary person as he steadily climbs to the top, but he definitely won't become invincible or show off.

I'm tired of the usual showboating and face-slapping formula, so I want to write a story about someone who is ruthless and doesn't waste words.

He won't chatter on endlessly, but there will certainly be plenty of insight into his inner journey.

Because what I want to write about is the transformation in the protagonist's mindset.

It's perfectly normal if you can't get into it. This book takes a little patience to read.
