Sheer Heart Attack, Part 2 (Chapter)

Sheer Heart Attack, Part 2 (シアーハートアタック その②), originally in the WSJ release, is the three hundred fifty-fifth chapter of the JoJo's Bizarre Adventure manga. It is also the ninetieth chapter of Diamond Is Unbreakable.

Summary
The miniature Stand named Sheer Heart Attack is presented as a substand of Killer Queen.

Koichi Hirose tries to dash toward the killer but is stopped by Jotaro Kujo, who warns him about possible traps. Sheer Heart Attack effectively explodes, narrowly wounding both Jotaro and Koichi and disintegrating the shop owner. Moreover, Koichi hears a door shutting, meaning that the killer got away, and wants to chase him, but Jotaro advises to ponder their move, being certain that Sheer Heart Attack is still present. Koichi is skeptical, and lets his guard down, letting the substand take him by surprise. It jumps on Koichi's head and begins to roll on him, hurting him with its threads. Jotaro summons Star Platinum who heavily pummels Sheer Heart Attack, but it surprisingly remains unscathed. Koichi warns Jotaro that touching it may trigger an explosion, thus Jotaro stops time and pummels it even more heavily and punches it into the ground. Unfortunately Sheer Heart Attacks leaps out of its hole and goes to attack again, being invulnerable to Star Platinum's might.
