Ninja God In Comics Chapter 509

Before traveling through time, Roger had seen such a setting in an anime.

The giant's fatal weakness is located at the back of the neck, which is 1 meter long and 10 centimeters wide.

Of course, this is just a setting in that anime.

In other worlds, the giant's Achilles' heel is not necessarily at the back of the neck.

However, this still does not affect Rogue's desire to attack the back of the fire giant Surtur's neck fiercely.
