Key Points
1限界( = “at my limit”
- In this scene, 限界
( means Mina has reached the point where she cannot comfortably keep going as she is. - It is not an abstract “boundary” here, but her practical limit: she is so hungry that she feels she cannot make it through the next class properly.
2もう限界( だよ = an emphatic complaint
- もう adds the feeling of “already” / “I can’t take any more”.
- だよ makes the statement direct and emotionally pushed outward, like Mina is blurting out how bad the situation feels.
3こんなんじゃ is a casual contraction
- こんなんじゃ is a spoken shortening of こんなのでは.
- Here it means “if things are like this” or “as things are now”, referring to her current hungry condition.
4できない = inability to do something
- 集中
( できない is “be unable to concentrate”, with できない showing inability rather than simple refusal.
