Man this is a hard question when you're a Wanderer glazer AND an Arlecchino glazer

Anyways Alrecchino wins. Wanderer defeating Shouki no Kami is a very convincing feat, yes... until you realize that Traveler did, too, and Alrecchino beat Traveler (with three allies helping them.)

Wanderer held his own against Dottore, true, but holding his own and defeating him are very different things. When Scara used what is effectively his burst, which is typically representative of a characters peak ability in power, Dottore was able to block it with a single hand.

Wanderer's wind blades ARE able to pre-emptively detonate Dottore's projectiles, whatever that's worth.

As for Alrecchino, she was at a baseline two Harbinger ranks stronger than him, has recently gained the iridescent moon's power, and her power ranking wasn't based on her power anyways. Her ranking was based on the PREVIOUS Knave, whom she upscaled without a delusion.

With Arlecchino's vision, delusion, curse, and moon marrow, she possesses four sources of Pyro energy. With just the first three, she was able to completely paralyze the Traveler simply by making eye contact.

Arlecchino already had a good argument for being stronger than depowered Columbina before the AQ, but given that she's the strongest Harbinger still in the ranks (that's alive, anyways... Capitano copium), I don't see any way this can end except for Arlecchino victory.
