About this converter

Fullmetal Alchemist by Hiromu Arakawa ran in Square Enix Monthly Shonen Gangan, ch. 1-108 across 27 volumes. This page compares 10 arcs covering the full run, from the 5 chapter Elric Brothers intro to the 25 chapter Promised Day finale. Rows merge adjacent official sub-arcs so the file stays contiguous from ch. 1 to ch. 108 with no gaps. Counts come from Square Enix tables of contents, cross checked against the Fullmetal Alchemist Wiki arc pages. Bones adapted the complete run in Brotherhood episodes 1-64.

How to use it

Pick two arcs and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 Promised Day arc against Scar Return to see the 25 to 4 gap. Then test Briggs against Elric Brothers intro to compare 21 chapters with 5.

Merges group neighbors only. Rush Valley joins Separate Ways, the Xing envoy chapters join the Dublith teacher row, and the Marcoh and Ross pursuit chapters join the Hunt row. The Briggs row runs ch. 63-83 for 21 chapters, though one infobox prints 20 by miscount. Gaiden extras and the final bonus chapter sit outside these rows. VIZ English volumes collect the same chapters in 27 books.
