Right next to the Mother Sea, driplets dropped on Aqualia Town, blessed by water. The waterways that have been created all over the place sometimes also let evil waters drift. Coming from the sea, in a waterway one wandering demon swims elegantly. To take back their ordinary lives, the town's traffic network has been blocked off.
That quiet and beautiful stream was more than enough to make the autonomous drivers powered by water work. However, that was just when this power was used in a right way. The flowing clear stream gave birth to a negative cycle. The power of the water that been abused destroyed the divine protection of the city, and broke this peace.
The water flows beautifully, the young blue dragon from the deep sea showed up in the Capital. The tsunami was evoked, the breakwater was breached, the threat of the sea hit the Capital. To suppress the power of water, the force of wind must arise. To resist the threat of the sea, collect the wind in your hand and attack.
