I don't know why did WIT studio even work on this, after so many great titles they had produced ranging from Shingeki no kyojin to Vivy to this mediocre product.. It's strange.
The plot summary is basically Miracle wants to become a successful Virgin tuber like Kizuna Ai.
the overall experience is terrible and would not recommend it to anyone, If you're accustomed to "Vtuber culture", it still doesn't have anything exciting to offer at all, you only get weird, unimaginative and an empty shell of a story. The character designs are cheap and bellow average whilst the overall animation is hella stiff and boring, a lot of static shots and painful brain damage.
If you despise 3D animation, then you will hate it since they use it a lot especially in the music performance sequences which is what you find on vtubers youtube channels so it's low effort from their part. Only kizuna Ai's sequences are somewhat average but the rest is really poor.
The dialogues and overall writing is bellow baby comprehension level which is one of the most cringy things I've seen so far in anime medium. Like : "Oh wow! I'm lacking the skill to speak so "I need to learn to speak better". "Kizuna Ai was the best I love her so much".
The side characters are all one dimensional and add nothing to the already boring narrative, even the ultimate goal set by Miracle is laughable. And what's worse is that they have a prize for being the best cringy Vtuber creator Which no one would ever care about.
All in all, there's plenty superior shows this spring season 2023 to watch so don't bother with this one as it doesn't have anything special to keep you entertained. The music is trash, the 3d and 2d are cheap as hell and the story is just abysmal.
