One Piece vol04 ch027, volume page numbering. This time I'll try to make it like this.
(edit) note: In this and previous chapters (25-27) I use a bit nonstandart line breaking. "\" separates several merged bubbles, and "\\" separates just different bubbles. No indication of panels change. I might correct this later.

Usopp: ..........!
Kuro: Pirate... "a brave warrior of the sea"?// What an outrageously twisted wording. // But!.. Your savage self is the best proof... // You always brag // and whenever displeased, you resort to violence!..
