First off, much love to the translators - you've done a great job, & thanks for your hard work.
This manga started with some promise but was ultimately really disappointing. I thought the lowest point was going to be the completely unearned, hacky ~tragic backstory~ that isn't redeemed by the end through some twist or recontextualization (the only thing I was waiting for before deeming this true garbage). Then the mangaka changed Youko's character design to shoehorn in a swimsuit scene.
Overall, my biggest complaint is that Reika's character just isn't well-written. Surrounding your pet character with dumbfucks who are denied the agency, intellectual competence, and curiosity of an average adult doesn't make your pet character smart or a "true protagonist" - it makes you a YA novelist. Even with this massive advantage, the story feels compelled to TELL YOU "REIKA IS SMART" because she actually comes across as an idiot who should've died many times over.
If you like this story, you're a pleb. Read more.
