Viewers who saw the trailer had an idea what the tone of this show would be.
We began the episode with a preview of a cute doll/android girl preparing to battle enemy robots on a train. Thirty years later the main heroine of the show, initially unnamed, awakened with “protagonist amnesia”. The first thing she saw was a broken doll. As she tried talking to her she heard cute singing. She ran out of a cafe in search of the singer.
It was a cute girl later named Chiyo. She came from a district sealed due to enemy attack. She recognized our heroine being an automata, a doll created to help humans. She also bragged about knowing a super cool one who’s like a big sister to her but she hadn’t seen her in a long time.
Suddenly a rampaging enemy robot spotted them. As it’s charging at them our heroine stunned it with a song then disabled it, passing out afterward. Next day she woke up in the office of Nagi, owner of the cafe and doll craftsman. He named her Haizakura and explained the reason she couldn’t remember anything beyond her programming was her memory was reset after being repaired. He offered her a job at the cafe.
She met her coworkers/senpai. From left to right we had Houkiboshi, Gekka and Karasuba. Houkiboshi was mute, Gekka’s the cute one and Karasuba the tsundere. As shown in this screen grab we got a montage of Haizakura trying to learn but failing spectacularly.
During break she went outside and Chiyo spotted her. She properly introduced herself and they continued talking about her big sister Yugiri. We saw a familiar looking silhouette but when she showed their photo it’s clear Yugiri was the broken automata. Nagi said repairing her would require giving a complete reset similar to Haizakura. The reason she broke was because her mind overloaded during a great battle. It’s too much for her and she shot down. For the time being he suggested Haizakura tell her about Chiyo and see what happens. As she did so she sang a similar song that stunned the robot and her eyes glowed red again,
The next morning she’s surprised to see Yugiri awake too. She took her to Chiyo and we’re treated to a precious reunion montage. Unfortunately the happy times were extremely short lived…
Yugiri couldn’t remember her time with Chiyo at all. Not even her name. Haizakura hoped there could be a way for them to remain together but she feared what would happen once Chiyo noticed her robo dementia. An automata’s greatest fear was having no purpose. Their farewell was as sad as one would expect. Yugiri went back to “sleep”. Karasuba did her best to cheer up Haizakura who wondered if reuniting them was the right thing to do. We ended the episode with a strong and fetching woman’s arrival.
Good premiere giving us a sign of what’s to come. Next episode looks to be about Gekka.
