If You Were Here is an Alicization what-if story, answering the question of what would have happened if Raios and Humbert hadn't been around to force Eugeo and Kirito into breaking the Taboo Index.

In this timeline, Eugeo and Kirito graduate from the Swordcraft Academy, win the Four Empires Unification Tournament, and become Integrity Knight apprentices at the Central Cathedral. However, Quinella (Administrator) and Cardinal are still at odds with each other. Can Kirito find a way to resolve their century-old conflict and bring the two to work together?

— The story was released as a bonus with the 8th BD/DVD volume of the Alicization cour 1-2 Blu-Rays/DVDs and is based on Material Editions 28 and 29, with 50 pages of original content not part of the M.Es.
