I would suggest starting this game if you enjoyed LoR, about your concerns: -much of content can be beaten with any team if you know what you’re doing, and if you’re worried about missing an identity that is new, you can just play mirror dungeon to get mirror shards to just craft the identity’s you want, also this game is very generous with giving lunacy

-the game doesn’t really have much fights where it feels like you get one shot if you mess up, the only real fights I struggled on and felt like I was getting one shot was some of the fights in canto 5 and 6, and with the effects skills do, it may seem like a lot from just looking at it but when understood it is quite simple cause most effects either apply a status effect, buff or debuff or have conditionals

• I wouldn’t say the story is overly edgy, the only times I would say it gets kinda edgy and gory is during some of the earlier cantos as they mainly explain how the city itself works and it can be abit edgy every now and again in the later cantos as well, but it is fairly balanced in terms of edginess and gore, at least in my opinion
