Suijin

Suijin is the Water Goddess of a lake that is nearby a village that Inuyasha and his comrades come across while Sango is recovering. Six months before their arrival, she was overthrown by one of her own water sprites, who stole her Trident and had her sealed away in a small cave due to her tiny stature without the powers of her trident. He then went on to pose as the Water God of the lake, beginning to demand sacrifices of the first born sons of the villagers nearby in repayment for keeping away droughts or floods. He also used the Trident to turn fish and crabs into his servants using its spells.

Inuyasha and his gang show up in the village and realise what exactly is happening when the son of the Village leader enlists their help in defeating the Water God to stop the sacrifice of his best friend in his place. The imposter floods the shrine however, they are saved by the sprites that tell them the whole truth of the fake Water God's identity. Inuyasha goes back to save Kagome while Sango and Miroku go to the saves to find the goddess. They release her to find her tiny body and bring her towards the battle.

While there, she parts the water with one of her earrings so that the others can observe the battle with the imposter, who begins to summon hurricanes that could destroy the village. She calmly informs them to return her weapon to her and she could simply solve the problem. When the Trident is returned to her, she returns to her former height upon touching it and immediately proceeds to get rid of the dangerous winds and hurricanes. She returns to her former position as Goddess of the Lake.
