Continuation? Yes.
Fan service? Yes.
The first episode throws you straight into a situation where, if you haven’t read the source material, you will wonder who is the new girl and why do they live back in the house now. However, All that is sidetracked as the episode serves fan service on a silver plate. A lot of skin, with the kind of nudity where nipples simply doesn’t exist when it isn’t covered. It ends on a semi-side adventure with Hina.
The second episode, which was released 2 years later and takes place several years later, takes a rather opposite approach with no fan service. Heavy story driven and from the perspective of some characters that haven’t been seen much, while omitting others, in a sort of interesting take and overall it finishes up the whole story neatly and heartfelt, especially if you wished for a certain outcome.
