An unlucky kid who has achieved great success because his luck is so unlucky. She was struck by God's system for selecting the next generation of heirs, and became a otaku orphan (originally female). For some reason, romances came to her one after another. Unfortunately, they were all beautiful women, but she was a straight woman. Moreover, the master of the system is a scheming + evil person. In order to "survive" in such an environment, he can only meet and kill gods, keep learning, and eventually become a god.
Ps: This is actually a story about a straight woman being turned away.
