Datatsushi is the main antagonist of Siren and an unseen antagonist in Siren 2.


Siren 1

Datatsushi is a powerful alien who crash-landing at earth, he was killed when the people of Hanuda suffered a famine and ate him in the belief that he is a gift from the Gods. In his death, he cursed a girl named Hisako Yao, who would then spent countless centuries trying to resurrect him.

Hisako uses ceremonies that center around using any of her descendants with psychic powers as the bride of god, sacrificing them so that their blood can resurrect the worshipped alien, one such ritual in 1976 fails, resulting in the town being buried in a landslide, part of Hanuda is pulled into a alternate dimension.

In the alternate reality, the water has been replaced by a similiar red substance, which allows people to turn into Shibito. Days later in the game, a man named Kyoya Suda defeats Datatshusi from that reality.

Siren 2

His Red Water is present in the second game, although the antagonists now are two creatures similiar to him: Mother and Otoshigo.
