Suijin's cabin looks like an Okinawan house. It has seashells dangling from the ceiling and sea breeze drifts around the cabin, giving it the smell of the ocean. It is beside the Mizukami River. Pipes connect the cabin to the river.
Children of Suijin have the ability to conjure a weapon out of water which can be used for combat; however, only one weapon can be conjured at a time and it cannot be bigger than the one who conjured it. They can also make small non-combative objects out of water.
Children of Suijin can create a large tidal wave, which can be used to violently assault others with strong waves and water. The larger the wave, the more energy it drains and it cannot be larger than a tsunami.
Children of Suijin are able to use water to create a semi-living construct, no larger than 2 to 3 times the size of the user, that lasts for a short time to fight for the user. While the construct is fighting the user is incapacitated, the longer they maintain the construct the more energy it drains.
Children of Suijin are able to transform their bodies into pure water for a short time, they have a higher resistance to attacks but are weaker in their ability to counter attack while in this form, the longer they maintain this form the more energy it drains and the longer they will need to rest between transformations.
