[Nagisa took a trip to the Prism Lake and decided to do a bit of sight-seeing before catching an airship back to the city. He did not bother reading the quest board in full before heading out on his trip, because the quests mostly don't interest him, so he has no idea the bridge was among one of the things that the residents asked the guilds to investigate. Surely nothing could go wrong!]

...Look at this bridge. Isn't it strange?
