The Danger Files

These "Danger!" creatures are full of mystery and intrigue, but after hiding way on their treacherous island for so long, humans are finally able to take a closer look at them!

Hunt them down... before they hunt you.

If you find it difficult to deal with monsters with high ATK, try to increase your ATK with the "Second Expedition into Danger!" or "Danger! Feets of Strength!" effects, or aim for a direct attack with the "Realm of Danger!" effect.
