(Review in Progress) This is the current work of the author who wrote both Yankee-Kun to Megane-Chan (Flunk Punk Rumble) and of course Yamada-kun to 7-nin No Majo (Yamada and the Seven Witches). Both of them good series in their right and they both had their own criticisms but they both had a lot of charm to them to keep you reading. I had to mention these two series first because it's not as funny as those two were, doesn't have a big and colorful cast, not really much drama as I thought it would have for love comedy harem, and it feels like there's not much of foundation to keep you interest. I'll get more in depth but the reason I kept reading was because Yamada had a down time in its series in the middle but it managed to bring itself up to the conclusion... Yankee was a bit of the opposite... but still a good series regardless!

Story (4): All I have to say is that this third series had a lot to live up to after we got both Yankee and Yamada and all I have to say is that it's no where near as good as those two. It's a harem, between his set up to be Fiance Erika Amano, his test score rival and crush Hiro Segawa, and (possibly? It's been over 40 chapters and they still messing around whether they both just see each other as siblings or not) his thought to be biological sister Sachi Umino. The first chapter atleast simplifies these three as the main contenders buttttt there's no conflict..... It feels like there should be conflict but there's none whatsoever, we kept being told that there's a storm brewing the next chapter but again nothing ****ing happens and everything is resolved... I'm going to mention Yankee and Yamada again real quick here, in 48 chapters we get to meet a bunch of characters, had some conflicts, had a bunch of laughs, and we get to see some sort of drama... Cuckoo ain't got none of that, I laughed a few times and most of the 'love' situations are so forced that its cringeworthy and one more thing to note is there's not really any story arcs atleast up to chapter 48.

I'm just hoping the story picks up from here... please do.

Art (7): It's certainly the same as the last two series so I don't know why it feels like she got a bit lazy with the character designs.

Character (4): We only got 4 characters that the story revolves around and they're odd. Lets start with Nagi, he's the main character of this manga but there's really not much known about him... he has some quirks that can be explored but they're not really explained like how he's supposedly really strong but no one mentions it and there's more but I rather keep this short and say that after 48 chapters, there's still so little we know of him....
Erika... I really don't care too much for her and all her interactions with Nagi seemed super forced, the chapters with both of these two are usually the ones I can't get into and had to motivate myself to keep reading, she's not per say a bad character.
Sachi is probably my favorite character in this mostly because she's interesting, she has actual traits of being a complete character and the chapters she's in are some of the ones I look forward to.
Hiro... she's alright, nothing bad about her at all but there's seems to be something up with her and I look forward to seeing what she's up to.
Okay that's it, in 48 CHAPTERS, there's only been little development with and between these characters, and there's only one other minor character that's not their parents but he rarely shows up and you don't really get to know much about him at all!

Enjoyment (4): It's disappointing even without comparing Yamada or Yankee, it's still really disappointing. I only read because I was such a big fan of the mangaka and was hoping to see her get more attention but this is not it chief.

Overall (5): One question... How did they not know that their kids were switched in the first place. Like imagine this, didn't they get told what gender their baby was before they sat them in beds, did they atleast see what kind of colored hair their babies had, and I can keep going but I'll stop here. Okay lets ignored all of the above and try to get into this situation, wouldn't you be questioning your spouse because both Nagi and Erika had no similar traits as their 'mother' and 'father'. It's one of the biggest nitpicks for me and I just can't get over how dumb that sounds, but I guess it would make sense if they were the same gender and had the same colored hair but what ever... Just ignore this big elephant of a question if you truly are going to read on.
