In summary this is about adorably awkward twins trying to solve the mystery of their mother's death -
Migi and Dali are 13 year old orphan twins who have lived a sheltered life and have an unusual way of interacting with the world as a result. The story follows them as they try to solve the mystery of who killed their mother when they were 5 years old. From this, they have a view of the world as hostile.
It's really adorable to see them try to understand other people with the presumption that others are hostile and malicious. And then, once they find that others can be trusted, they come up against those who are hostile as they get closer to undercovering who killed their mother and why.
The story is full of twists and turns making you eager to watch the next episode. There is great character development, both in the twins themselves as well as their ability to see other characters as being multifaceted.
I found the animation beautiful and the voice actors (english dub) doing a superb job of bringing life to the show.
Additionally, I really enjoy the music for the opening and ending credits; I watch them in their entirety for every episode. It's such a fun show that it makes me sad that there are only 13 episodes, and that is why I couldn't give it a 10 because they could have taken their time, as the last 2 episodes although superb felt rushed.
Honestly, as I am watching this in 2025, it is so far one the best animes I've seen this year and in my top ten list of best anime series. I highly recommend.
