Karenai Sekai to Owaru Hana is a nakige with some positives but it also struggles a bit with a story that is very one-note to its detriment. Past that it's pretty standard fare. To me it's another visual novel where the positives and negatives cancel out to where it's just fine.

Characters are interesting enough. There's a perverted onee-san type, a cheeky kouhai type, a kind and caring type, and a cutesy imouto type. They all fit their stereotypes fairly well, although there isn't much time spent on characterization beyond the basics, so don't expect very deep characters here. There's also not much character development in this visual novel - partially due to its relatively short runtime (7:23 for me). There are no real standouts here, but nothing particularly grating either.

The story is both where this visual novel shines as well as the largest area of failure in my opinion. On the positive end it manages to be a somewhat effective nakige in a very short period of time. It managed to get me emotional within the first hour and a half of reading, which normally does not happen. For me though, once that was successful there was no truly effective comedy or break in the serious mood. It had a few comedic moments but very quickly dove back into serious issues, which led to a feeling of it being a bit of a slog to get through and greatly diminished what emotional impact was there. Most of the aimed comedy moments were the tired and cliche straight / funny man bits, most of which were as cliche as they come, with nothing feeling original at all. I think if you enjoy the kind of comedy here then you'll likely feel a lot more positively about the story as it would have broken up the serious parts quite a bit better. All the story bits were also foreshadowed well in advance, to the point where I had figured out where everything was going by the time the prologue had finished. Take from that what you will, but for me it was another aspect where it diminished the emotional payout when it can be seen from that far away.

The epilogues are where all the moe and cute moments are, but they're not very long and are probably 60-75% H-scenes

all take place within the epilogues. There's 10 total H-scenes in total that would feel at home in a Marmalade title.

I found the art to be very pretty, and the direction aided here, especially the multiple scenes with flower petals being animated along the screen, but there's not a lot of CGs or backgrounds present. Music is also fairly limited, but what is there is appropriate, although I wished the scripting of it was timed a bit better. The OP is a very pretty AiRi sung song, but the ED is a run of the mill Sagara Kokoro tune.

The fan translation done by Shinzou translations isn't bad, but it could've used more editing or QA work. It reads like it was translated from JP to Spanish and then into English. From the lines I listened to in full - admittedly very few - the translation itself is fine, but there's a decent number of typos and grammatical errors. For instance there were at least three times "tights" was in the script instead of "thighs". If this kind of thing bothers you then I would skip this one.

This title can be picked up secondhand without too much trouble and there's also a download edition. It worked without any real issues for me on a Windows 11 PC.

I'd recommend this to anyone looking for a decently written nakige if they're a fan of the cliche straight man / funny man type of comedy. If you're not a fan of that comedy it will likely feel one note to you like it did to me.
