For decades, the terrifying forces led by the Demon Lord from another world have been invading "Arcadia," a world developed with magical science.
Arcadia's nations united and fought with all their might, but were ultimately overwhelmed and cornered.
Realizing that their demise was inevitable, the people of Arcadia gathered their remaining forces and launched a final attack on the Demon Lord from another world, using their homeland as bait.

Area Introduction

To fight the Demon Lord, the Arcadian army must overcome two areas from another world.

1. Heavy Industrial Zone "Devil Factory": A massive factory said to manufacture everything from alien architecture to knives and forks. It draws lava from the sea for smelting and power.
2. Needle Mountain Wasteland "Dragon's Nest": A wasteland where sharp, rusty iron needles, some as tall as 20 meters, grow like a forest. It is a major breeding ground for dragons, and the sky is always filled with them.
   Beyond these two areas lies the Demon Lord's castle area.
3. Demon Lord's Castle: A castle like a colossal fortress. Its corridors are 100 meters wide and high. Guarded by elite monsters, the Demon Lord resides on the uppermost, finest throne at the very back.

Boss Introduction

These are powerful enemies that rule the areas of the other world. You cannot proceed without defeating them.

1. Iron Goblin: The ruler of the Devil Factory. A goblin that has abnormally evolved to a length of 50 meters. It is equipped with armor and a flail made from the hardest metal in the other world. Sadistic and prefers to thoroughly crush its opponents. Weak when approached closely.
2. King Dragon: The master of the Dragon's Nest. A super-large dragon 50 meters in length. It has single-handedly destroyed several nations of Arcadia. Its Dragon Breath is a super-heated beam that splits the earth. It is always flying, so it must be knocked to the ground.
