It looks as though the light novel adaptation will span across 3 episodes (223-225). For those who don't know, Hiro Mashima, who provided illustrations for the novel also approved the story. Given that and how short it is, i expect the episodes to be good with some nice pacing.

The light novel adaptation will be followed by an omake episode of a omake chapter that will be released 3 days prior to the episode airing. I expect to return to canon after that.

On a side note, Hiro Mashima is a beast. So far this year he is releasing an omake chapter every month, on top of the main series and FT Zero. I take my hat off to him.
