Personally I love this anime very nicely drawn, and its very well thought out. the story centers around a boy who ends up taking care of his sisters children since his sister n her husband died in a plane crash and this tells about all the hardships that he has to go through while taking care of the children. while some may say this seems like incest or to loli for their taste I feel thats not the case. the characters are not blood related so its not incest and they make this perfectly clear also the main character does not seem to have any romantic interest in any of the three girls he actually has an intrest in reika-san from his school. however this may be a little loli but considering the circumstances i feel that it doesnt cross any boundaries.
Now i know i said i like the story...however i do wish it was longer and the ending kinda confused me cuz i saw him stamp somesort of contract or something im guessing thats the deed to the new house at the end.
the characters were great hina makes the anime a bit more upbeat because of her funny 3yr old aspect and miu is like the mature younger sister (atleast thats how i see her) while sora is the older tsundere sister making the trio pretty fun to watch...however the one thing that annoyed me throughout the whole anime was that stupid club president i dont like it when a good anime gets ruined by one character that basically looks and acts like the viewer image of an otaku lolicon loving person (fat, ugly, glasses, drools over anything thats under a specifc age thats younger then 17) its the one thing that annoys me the most because i feel it adds more fuel to fire for outsiders to say something negative about it...maybe im overthinking but thats how i feel on it. however the rest of the cast was awesome and very enjoyable
overall the anime is great and i enjoyed watching it till the very end i really wish it was longer i wish they would make a season 2 and show them in the new house and continue the story but i dont think it would happen but hey its worth wishing for
