Firsts
  • The Mark-Mark Fruit (Mato Mato no Mi) homing only holds while Vander Decken keeps 'a sliver of consciousness' — knock him out and the thrown object stops tracking and falls
  • Decken can re-mark a fresh target with his left hand ('You're my left hand target now, buddy boy!') and uses it to redirect the falling ark Noah onto Luffy / the island
  • Zeo can blend invisibly into the ground — he was pinning Nami's legs unseen, the cause of her paralysis
  • Nami's post-timeskip weather weapon debuts in combat: 'Storm Cloud Rod' lightning and 'Black Ball', framed as 'carefully applied science, not magic' — she dubs herself 'Miss Sorceress'
  • Noah, the colossal ark, is shown in full for the first time (p.18 splash) and begins falling toward Fish-Man Island as the chapter's cliffhanger
  • The merman princes use Shirahoshi (Decken's decade-locked target) as a lure to draw Noah away from the island; Decken counters to ensure it crashes

Summary

At Conchcorde Plaza the Straw Hats hold the line against Hody’s four officers, the chapter cutting between four labeled duels — General Franky vs. Ikaros Much, Brook vs. Zeo, Daruma vs. Usopp, and Dosun vs. Chopper. Nami debuts her upgraded weather weapon (“Storm Cloud Rod,” “Black Ball”), insisting it’s “carefully applied science, not magic”; Zeo is revealed to have been invisibly pinning her legs; Usopp and Chopper beat Daruma’s tunneling with the hole-filling trick they learned in Alabasta. Above the plaza, Decken’s thrown ark Noah looms over the island. The merman princes Fukaboshi and Ryuboshi try to pull Noah off-course by carrying Luffy and luring it with Shirahoshi (Decken’s locked target), but Decken re-grabs the ark, marks a fresh “left-hand target,” and ensures Noah will crash. The chapter ends with the colossal Noah revealed in full and falling toward Fish-Man Island — Decken cackling “I’ve won, fools!”
