Synopsis : The anime starts with AIs in the distant future going on a rampage and killing any human in sight all the while humming songs . A scientist named Matsumoto sends an AI program 100 years prior to save humanity from the coming genocide by the world’s first autonomus humanoid AI. It is a 100 years burden of a project called “Singularity”. With the help of a sidekick AI, Matsumuto sends it across to the past.

Personally when I heard this synopsis I was expecting some IDOL shit with robots but boy the first episode caught me off guard. As expected, Tappie Nagatsuki who is the author of re zero, did excellent work in time travel stories again.

Vivy/Diva : World’s first autonomous humanoid AI whose mission is to make everyone happy with her song. The way she was represented gave me a lot of violet evergarden vibes. Always curious about her “heart” and what it means to pour her heart into her songs.
Mastumuto : An Ai sent by Scientist Mastumuto to help vivy in project singularity. I found him too talkative and over confident. He spoke way too fast but it suited his personality . He was straight forward to his mission and did not change any unnecessary events affecting the future.

Animation : Overall the art and animation were good. The fight scenes were smooth , fluid and entertaining to watch. Every episode has few close-up shots of characters at some point which are much more detailed than the rest of the shots. I wasn't really a fan of this sudden change in artstyle but it grew on me each week. Don't really have complain about CG scenes but they could be better specially the end of episode 6.

Sound : In any of the fight scenes or even normal scenes you won't find the sound track being out of place.All the songs which were sung by Kairi Yagi really felt like she understood Vivy/Diva as a character and was living as her. There are few different ED’s which were songs by character themselves on whom the current arc is based on and all of them fitted perfectly on how that particular episode ended. As soon as I heard them, a few of them directly were added to my playlist .

Personal thoughts : Not a single week have I felt bored. Every episode had an impact on the story and something which would get you excited about next week's episode. It had just the right amount of fight scenes not much not less and all of them were executed well. The final episode might have been a bit predictable but the way it played out was amazing. The story of how an AI learns to pour heart into her song by living the memories she made over the course of her 100 years journey and how each person she met in her life had an impact on her. I might be biased over this anime because this was something I have craved from ages since I am not really a fan of the shounen genre and I really like sci fi and time manipulation. Would really recommend this anime if you made it till here.
