Summary
Koichi, looking at the petrified Echoes, believes that it died out and despairs, not noticing that the shell is breaking. However Yukako sees the shell revealing another Stand inside and tries to enter the house. She manages to crush the furniture blocking the door, and enters the house, but whatever was inside the shell has disappeared. Angered, she questions Koichi about where he hid the thing in the shell, but Koichi doesn't know anything about it. Both look up and see the new form of Echoes.
Yukako is initially unimpressed, but she suddenly feels a violent whirlwind propelling her out of the house and above the cliff. Yukako manages to grab a tree with Love Deluxe, but is confused about what happened. Meanwhile Koichi sees that on the door Yukako was leaning against, Echoes has planted the sound "Whooosh" with the tip of its tail. He understands that his Stand has evolved into a more powerful form, and encouraged, dubs it Echoes ACT 2.
