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. One box holds a count of the first arc, one holds the matching count of the second, one holds total chapters. Try Spring Koshien against Seido Entry to see 52 against 28.
Act II splits sit inside arc rows as listed. Anime cour splits follow different cuts outside manga rows. Completed Act I at 376 chapters anchors these ranges. Volume extras add no chapters and add no rows. Color spreads add art, not chapters, and stay out.
