These last 3 episodes have been such a ride. Atri's character has been a pleasant surprise. Started out really funny and silly. Turning into more interesting and complex as the show progressed. First cliffhanger we get the idea that Atri has been deceiving Natsuki. 2nd cliffhanger Natsuki comes to Atri.
Yasuda thought that triggering Atri to attack him would prove his point. Hurting Natsuki came as a matter of self-defense. Tbh at this point, Atri was at her breaking point, but no question her heart wanted to at least protect Natsuki. His words of apology hit home for Atri. For the first time, Atri no longer holds back to how she truly feels. Seeing her cry and exhibit emotion like that was such a well executed scene.
For much of the series, Atri has been the one trying to tease Natsuki. Sometimes getting him to blush and other times not so much. But him saying he likes Atri and Atri wanting to hug more understanding what it means to have a heart. To be kind and sincere and care about others.
We learned that the orders that Natsuki's grandmother was to take care of her kid. Who was Natsuki's mother, Shiina. Atri in her base form without a name felt very much a standard humanoid. As Shiina gave her the name Atri you really get to see the basis of Atri's personality come to be. Her high performance, her song and everything came from Shiina when she was in middle school.
The Shiina bullying incident was sad in many ways. From Atri's perspective, she knew something was wrong and given how Shiina was about to jump off the building, things were drastic enough for her to punch the bully. For Atri she had to make a choice, but the thing is she was a humanoid. Atri didn't know how to help Shiina. For humans, it is natural for us to make mistakes when we want to help those that we hold dear. Unfortunately, for Atri she is a humanoid and one mistake is what it took to call her defective. Still, Atri loved Shiina as well saw in the notebook with both words and tears.
It is so tragic to see Atri watch Shiina from afar. She watched her grow up and Atri couldn't interact with the person she deeply cared about. Then with Natsuki she faced a similar situation, but here she made the correct decision. Being there for Natsuki and comforting him meant so much to her. Perhaps that kind of affection could have helped Shiina when she was being bullied.
Grandma was aware of the fact and honestly feels like she believed in Atri caring for her daughter. Grandmother hiding Atri and erasing her memories was an act of kindness. Maybe there will be a time when a humanoid will be more accepted in society? So glad Atri has found a happy with Natsuki and the others.
