  • Beach Episode : It starts with the girls removing their clothes in the Hanamiya vacation house's changing room, as Yui mentally says that it's currently summer. After the opening, a scene similar to the end of episode 2 is shown. Only this time, she's wearing a different uniform, which is the school's summer uniform. After some contemplating whether she should interfere with this timeline this early; The other girls convince her to relax and have fun, which she complies. It plays just as what you'd expect in a beach episode, until it started raining and they were forced to seek shelter on a nearby abandoned research facility owned by Nagisa's great-grandmother. It started to go wrong after Sou encountered the ghost and fell asleep, while Yui seemed to have realized something. In the end, it's revealed that the 'ghost' was Nagisa's great-grandmother, back in WWII, who looks like Nagisa herself. And that in her perspective, it was Yui that was the ghost. They have a nice casual talk after Yui touches the AI Unit present(which is the one from Nagisa's great-grandmother's time). In the end, it was revealed that Uchihama academy was built by Nagisa's great-grandmother and it was because of her meeting with a young girl(Yui) that made her decide on such.

  • "Groundhog Day" Loop: Astronomy Club Finds Yui. Yui tries to prevent Kaori's accident. Accident happens anyway. Kaori enters into an irreversible coma. Yui shuts down. Astronomy club enter careers in science and medicine to try and save Kaori. An artifical body is created for Kaori in order to upload her mind into a healthy brain. The attempt fails. Sou figures out that Yui was sent from the future to save Kaori. Sou remakes body made for Kaori into a second Yui. Sou finds way to send Yui back in time. Sou sends Yui back in time to save Kaori. Rinse and repeat.
  • In Spite of a Nail: Despite Yui's best efforts Kaori is still hit by a truck and put in a coma Episode eight of the anime.
  • Love Confession: Kaori confesses her love to Sou in every timeline before the accident.
  • Nice Job Breaking It, Hero!: It turns out that the "ghosts" that are being sighted all over school Are the quantum shadows left by Yuis from various other timelines that have gone back in time to prevent Kaori's accident. The more often the "Groundhog Day" Loop repeats itself, the more shadows appear and the more students are put into comas by them as a result.
  • Set Right What Once Went Wrong: Why Sou created Yui and sent her back in time.
  • Ret Gone: Yui's ultimate fate when she finally succeeds.
  • Ripple Effect-Proof Memory: Everyone who knew Yui is able to remember her to some degree or another after she is Ret Gone. This is due to the influence of their memories of her in alternate timelines. This means that Sou will eventually create Yui in some point in the future in the timeline where she has succeeded in her goal, just to see her again. This is also what causes Kaori to awaken in the timeline where the accident does happen.
    • Taking the OVA into account, Yui had a hand in the creation of Uchihama Academy by inspiring Nagisa's great-grandmother to become a teacher, explaining why she hasn't completely disappeared in their memories.
  • Rubber-Band History: Many references are made to the "chains of fate" the tendency of timelines to want to reconcile with one another so that not matter what changes anyone makes to the details. The Broad Strokes of how history turns out is more or less the same. This makes making meaningful changes to history extremely difficult.
