After entering the deep area of the mysterious Island, they found that the density of monsters here had actually gone down by quite a lot. Even after they walked for more than 30 minutes, they were not attacked by any monsters.
After about 30 minutes, they came accross their first monster encounter of the deep area. The monster they came accross was a level 560 powerhouse so Escora, Hibiki and Kizuna had no chance against it. So it was Elena who went to defeat this monster.
Just casually defeating it was fine but boring. So Elena decided to use this opportunity to teach some things to the three ladies. So she told them to watch carefully as she went to fight the monster.
The monster had a bizzare head which was just a ring. It did have two extremely small eyes at the two sides of the ring but Elena was not sure how useful these bead like eyes actually were for seeing things.
