A few important things on this page!
1. Juvia and Gajeel (i mean, ‘Lluvia and Gazille’ pffffff) destroyed dark guilds that were under the Oracion Seis’ control (and from Juvi saying ‘all those’, it implies many imo), so you can bet that the Oracion Seis were taking note of Juvia and Gajeel. Though there wasn’t any true loyalty between the dark guilds, the Oracion Seis wouldn’t want someone taking out their lesser guilds as it would weaken their own position. If Fairy Tail and the Raijinshuu continued taking out OS controlled guilds, then I’m sure OS would have started to focus on them as well. I’m saying that the Oracion Seis would know Juvia and Gajeel and would likely have had them on their own sort of hit list, they’d want to make them pay. So yes, Lucy, they were mad~
2. Everyone seems to forget how strong the Oracion Seis are/were but look, they’re a guild of only 6 and, as Mira says, were supporting a third of the underworld. Which was why it was decided that four guilds were needed to try take it down, and one of the members sent was a Wizard Saint, that’s how serious of a threat OS was. It’s also mentioned here that each OS member can defeat a guild single-handedly. I feel like this is particularly important for Sorano/Angel as people seem to have this idea about Celestial Spirit magic being weak, but like helloooo Angel was a Celestial mage and was part of one of the most powerful dark guilds and could/can take down guilds by herself using that magic.
3. Juvia is cute as hell. I love how proud she was of her strength/accomplishments like ugh
