As the monsters got closer, Sophia was able to take a good look at it. This monster did not just look like a mountain but was actually a mountain. Not just any other mountain but a volcano. If a volcano grew four little legs to walk around, it would look just like this monster.
Feeling the threat, Ruby was the first to initiate her attack. She immediately went into her berserk mode and attacked the monster with her full force. She did not even try any probing attacks as she was sure that this monster was stronger than her. From the way this monster was moving, Ruby judged it to be exceptionally slow and she was sure that it would not be able to avoid her attack.
But it turned out that this monster had no need to avoid any attacks. As soon as it noticed Ruby attacking, its whole mountain-like brown body turned black. Then when Ruby connected her attack, she did an almost negligible amount of damage.
