And thats exactly how you should watch it!
If you're like me and just finished watching Angeloid of Clockwork OVA and want to conclude your Otoshimono experience by watching this. Boy, are you in a for a load of confusion.
Now if you're confused thats normal because Angeloid of Clockwork takes place in Chapter 39/77 of the Manga. The first 5 mins and the last 5 mins of the OVA takes place from the final chapter (Chapter 77) in the Manga. See the gap? Basically the people that made the OVA expect you to have read the Manga already.
To avoid spoilers, The OVA starts off really serious because its the final chapter, then a flashback happens and you spend the rest of the OVA filled with recycled jokes and fanservice. Then after the flashback we come back to the present where we see a brief 5 min scene of the final chapter with Icarus/Ikaros and Tomo flying and talking before reaching the Synapse and BAM! Credits kick in! Yeah, it ends on a f**king cliffhanger.
So to conclude, if you're a fan of Sora no Otoshimono you have to read the manga no matter what. I suggest after Angeloid of Clockwork just start reading the Manga from Chapter 39 till the end. And if you still want to check out this OVA I highly suggest re-reading the first part of my review before watching
