Kuro Sakuragawa

 As a young man living in the traditional Japanese home with the rest of his family. One day while eating with the rest of his family, the rest of his family members, including possibly siblings appear to collapse and die within a few seconds of eating. His mother revealed to him that the food he was given was Ningyo and Kudan meats as part of the Sakuragawa family's mission to create an individual who could forecast the future. To see if the food actually worked, his mother submitted him to many experiments that involved cutting him open until he stopped feeling pain or it did not affect him anymore. He was one of the only ones who survived, alongside his cousin Rikka.He lives a fairly normal life as a high schooler, even finding a girlfriend, Saki Yumihara, and later going to the same college as Saki Yumihara. He was a guest at Rikka at H-university, in which he was a 2nd-year student, and also was a student in their law school. Saki discovers his true identity when they run into a kappa visiting a shrine. The kappa flees in fear. She decides to break up their relationship and relocate to a different city to work immediately after she graduates.
