The OVA Astaroette no Omocha is a three part short story series. In the first story, Lotte and Asuha find themselves searching for details about their school project. In the second bit, is the backstory to how Zelda came to be Lotte's bodyguard. The final of the three, is a flashback of how the queen met Naoya and how they conceived Asuha ten years prior to the events in the anime.
This OVA for Astarotte no Omocha contains two portions. The first is just additional fan-service with Asuha's class assignment being studying everyone's panties. The second part retells some of the history of how Naoya met Astarotte's mother (and thus supposedly how Asuha came to be...).
This is an add-on that should be watched after the parent story, if you so choose. The animation and sound are identical to the original, you still get marginal ecchi though with the second part you do get some partial nudity on Mercelida. Story is divided as the first part is pure fan service while the second part actually helps clarify
Naoya and Mercelida's past, though it's also a bit creepy as Naoya looks way beyond underage...
It's a short 30-min watch so if you liked the original then you'll enjoy this as well.
this might be a short review but otherwise let get into it
Story: so this OVA is basically split into 3 parts. 1 being that asuha is doing a school project on underwear and what not not much really here other than that. 2 being that how Zelda became Lotte bodyguard not really else too say cause thats really about it. 3 being on how Naoya and Mercelida basically had said (theres no rape honestly) they basially had sex in a dream (honestly wish they would have a done abit of Asuha and Naoya being they before they went back again)
Art: its the same as the
anime but good
Sound: sound is good still have the same OP and ED for the main anime otherwise it was decent
Character: Nayoa is actually a pretty cool and nice guy he does eventually grow on Lotte and of course without having there moments at the start of the anime. Lotte is the main girl and is the one who hates men but she a pretty care free and normal succubus. Asuha is pretty crazy for a 10 year old she barely wears in panites and often gets on lotte bad side but yeah she pretty care free aswell (i pretty much took this from my review cause it would have been pointless saying this again) Mercelida is the mother of both asuha and Lotte she also had sex with Naoya which made Ashua (cause you hopefully can tell lol) but care free and honestly horrible mother at that.
Enjoyment: personally i didnt care for this comedy wasnt there and just didnt feel good for me if your a lolicon and love ecchi (which i do not the lolicon part but ecchi part) than this will be for you
Overall: it get a 5 out of me you personally dont need to watch this but if you want some backstory (if you can even call it that) on the main anime than go for it and watch the OVA
