Zenless Zone Zero: Nicole's Brother Is a Sister-Obsessed Guy Who Uses Water Breathing

My name is Nilo. I have a younger sister named Nicole, the same name as Nicole from the game Zenless Zone Zero. The two of them really are so alike.

They both love money, have pink twin tails, and run companies.

But everything changed after that day. My sister died in that car accident.

After I killed myself, I transmigrated into Zenless Zone Zero and met... Nicole Demara, whose soul had merged with my sister's.
