Here's the delayed photo story website preview this month:
Spoiler for Oz Photo Story Ch 19 Preview:
Summary: A peculiar mission request is sent to Orpheus: a letter of challenge from the Britannian knight Dasko la Clermont! Orpheus surprisingly accepts this request, and heads into a duel in Chernobyl against Dasko and his Gekka Alonso!!
Highlight: Dasko la Clermont has reappeared for the first time since he was injured in chapter 6! The serious Knightmare battle here for the first time in a while is one of the highlights of this chapter. And the Byakuen’s Gefjun Breakers is used in an unexpected manner at the climax of it! Please confirm this scene’s CG by all means in the magazine.
Also, there was an error in my earlier translation, it's Gekka Alonso, not Alfonso. It's been corrected now.
