Average story with the basic imouto trope of being left alone unsupervised with her oniichan The artwork and sound were average, nothing spectacular but definitely passable. Hana remained quite an 'innocent' character throughout the series and her idiotic tendencies reminded me of Yoshiko from Aho Girl, while her brother was the same old hentai MC with not really any character and more of a placeholder or a vessel/medium for the audience in the story. The best parts of the story were the amusing dialogues between Hana and her brother, particularly constantly bringing up the milk as well as her utter inability to do anything. In terms ofrecommendations, the series is an above average watch for sure purely due to how much I literally laughed out loud at the final scenes in the last episode which bumped the show up from a 7, subpar, anime to a memorable and comedic watch. Also after a rewatch the ice cream scenes were also quite amusing no matter how sexual it tried to be which made it even better
