 Isuzu, devastated after moving away from her childhood home, began to visit the Hibarigasaki science center to see planetarium shows of the southern night sky.After the science center closed down, its director gifted Isuzu with an old telescope, along with a key to Hibari High's rooftop, so she could continue stargazing.While stargazing one night with Chinami and Suzuha, Isuzu and You are visited by Mare, who recognizes Isuzu's "nightmare" and reaps it with her scythe, causing the telescope to fall apart in Chinami's arms.
