Event: Salvage Great Adventure

I'd already grabbed the rewards, piano parts, and all sub-quests with dialogue, so I'd been putting it off until today, but I figured I might as well do it all, so I finally got around to filling out the compendium, completing sub-quests, and maxing out special buffs. All that's left is to secure the prisms. I gave up on collecting them since I haven't even captured over half of them. Does anyone actually do everything, including the prisms? Well, I guess some people do... Those travelers are too amazing??? Did you all make it to prism capture? Did you take a commemorative photo in front of the aquarium? My screenshot count has exploded. I even made the self-proclaimed 'ordinary person' stand in front of the aquarium for a photo, sorry! Even if you dislike it, I end up taking pictures with things you're involved with and tracking all your reactions, it's just a gamer's nature (prejudice).
