About this converter

Sword Art Online arcs run 1 to 10 light novel volumes in Dengeki Bunko counts. Mother's Rosario at 1 and Calibur Early and Late at 1 share the floor as single volume arcs. Aincrad, Fairy Dance, Phantom Bullet and Moon Cradle at 2 each form the duology tier. Unital Ring at 8 spans Vol. 21 plus Vol. 23 through 29 with Vol. 22 Kiss and Fly sides excluded and Vol. 29 announced. Alicization at 10 tops from Beginning to Lasting across Vol. 9 to 18. Rows count volumes because SAO arcs are defined by novel volumes, not manga chapters, and the slug says volumes plainly.

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 volumes. Try Alicization against Mother's Rosario to see the longest against the shortest.

Unital Ring counts published Vol. 21, 23, 24, 25, 26, 27 and 28 plus announced Vol. 29 for 8; Vol. 22 Kiss and Fly is a side collection and sits outside the row. Alicization subtitles run Beginning, Running, Turning, Rising, Dividing, Uniting, Invading, Exploding, Awakening and Lasting across Vol. 9 to 18.

FAQ

Which SAO arc is longest?

Alicization at 10 volumes, Vol. 9 to 18.

Why volumes and not chapters?

SAO arcs are defined by light novel volumes, so rows count volumes.

Is Unital Ring finished?

No. Vol. 29 is announced, so the row counts it with the arc ongoing.

Where are these counts from?
