Firstly, the story is unique. A tall and amature 11 years old who has a short and mature 17 years old sister getting into troubles. But thats about it for the first episode and i believe most of the future episodes because it is a 3-minute anime. The bad thing of a 3-minute anime is the difficulty to tell story but the good thing about it is that it can deliver the punchline and keep viewers interested in the series.
The art and sound are decent, reminding me alot of morita-san. In fact, they made a cameo in the first episode. As mentioned before, the characters are unique but the tall 11 years old boy sort of freaks me out a bit but i think i would get used to it. The humour are enjoyable and it is a relaxing anime to watch. I would recommend it for short breaks in between work to relieve some stress. And of course overall, i find it a decent anime and be sure to catch it if you like such anime.
