Anyone who loves the Monogatari series would love this anime. I'm not skilled enough to write a review without spoilers but I will try to minimise the spoilers as much as possible

The plot is about Makoto Niwa, a high schooler, due to his parents' circumstances he had to move to live with his aunt. There he discovers that his self proclaimed living alone aunt actually has a daughter, Erio Towa. Erio suffers from amnesia a few years ago, the reason is unknown, she claims that she was abducted by aliens but Makoto denies it. The plot can best be sumerised as "the boy who cried wolf's lie is the reason for the wolf's appearance"

From the starting episodes, we are lead by Makoto that what he thinks and says is the absolute reality for the anime. "Show me proof, if you want me to believe you" can be used to describe how Makoto chooses to believe or not at something. And is by that mindset that he denies anything that can't be proven. By having a denial mindset at start when doing anything, he is usually quick to give up on most things. He believes he is right because "if you can't prove that something does exist, then it does not exist" even though that is not actually proving that that "something" doesn't exist. Later on, as the frames pass by and the viewer jumps from episode to episode, the viewer will start to doubt Makoto's logical thinking. As Makoto meets more people and is presented with the belief of aliens by them, he still denies those beliefs. However, he will later on realise that "the boy who cried wolf" is actually himself and that his black lie will shatter all his beliefs, pride and ideology

Anyone who loves the Monogatari series will love this anime as well as it has Studio Shaft's unique presentation style when it comes to portraying characters' expressions, ideology, personality and beliefs. This is especially crucial for this anime as it relies on our main character to get us deceived

Although in the end, as expected for a 13 episode anime with such a large plot, it did not explained every important detail to us but I still love it
