Shingi and the rest of the party hid and waited to see what would happen next with that strange group.
A Nature Fairy was a pure good creature, trying to help nature and its friend and protect her land.
On the other hand, Ogres weren't that good. A typical Ogre was a dump creature who picked fights and did not care about anything. They were simple-minded and easy to control, so it wasn't rare for evil guys to take them as minions as they were physically sturdy creatures.
Usually, an Ogre was fat, unless it lived at a place well protected and hard to find food, but not as fat as one of the two Ogres here, and definitely, none was as fit as the other one.
So a Fairy helping those types of creatures was unheard of.
Also, Fairy didn't use classic healing magic but used the unique energy of the Tower that, until now, Shingi had seen only Floor Bosses using it.
