[Smartphone Ver.] Tentacle Armor and the Mystery Tower

Synopsis

A tower suddenly appears in the northern lands.

At first glance, it seems like a mystical structure.

But it could be a monster’s nest.

Or perhaps an ark of invaders from another world.

For the sake of the people living there, it cannot be left alone.

Not until they can explore it, investigate it, and guarantee the tower’s safety.

However, there has been one persistent reason why investigation of this tower has stalled.

To enter the tower, one must equip special armor that the tower itself has prepared… or so it seems.

One day, a captured thief named Salifa is brought before this tower.
