Clara just participated in the lottery in the school cafeteria at the instigation of her roommate. She unexpectedly won the prize and traveled through time in her sleep.
As soon as he passed through, he was teleported away again using a magic circle, so he was teleported again after passing through.
Everyone who travels back in time wants to have a gold finger. To this, Clara just wanted to say, "It's also very annoying if the gold finger is too thick!"
PS: I have only watched the old version of the anime, and this is fan fiction, so many things will be different. I hope everyone can enjoy watching it and don't always say that the characters are broken, because this is just a story in my imagination.
PPS: My writing is not good, so don't criticize me if you don't like it. I am self-aware. I just want to write the story I imagined and share it with more people.
