The main plot comes from miscommunication, things should've end quicker if they all just be honest and talk about their problem.
The 2 main character is a problem too, Yuzuki and Shione are very toxic, blaming MC for no reason, and keep rejecting her without any proper explanation, it's very irritating, makes me want to slap both of them in the face real hard.
The ending where the world is reset to saucerless city is very unnecessary, they should've just kept the story going with the disappearance of the saucer and fast-forward to the future where their kids or someone else does the summoning ritual and have Noel appears in front of them with a smile saying that she's there to grant their wishes and end the series.
