[Abo+mecha+falling horse+slap in the face+heartthrob+military academy joint examination+chasing wife crematorium] Isis is the youngest son of the Calypso family, the richest man in the capital planet. Unfortunately, he is the real prince who was replaced by a raccoon cat. When she was seventeen years old, Isis, who was living on the planet Quaia, was captured and taken for a universal gender pre-test. It was detected that Isis is actually the youngest son of the Calypso family and is very likely to differentiate into an omega. And Isis is 99% matched to Osiris, the son of the imperial admiral! After learning the news, the leader of the Calypso family immediately brought Isis back to the capital star. Isis suffered amnesia in a terrorist attack on her way back. The amnesiac Isis was forced to make an engagement with Osiris because of her high compatibility. Osiris was dissatisfied with Isis, who had entered into a marriage contract due to a high match, and ignored Isis even after getting married. Two years after the marriage, and the fourth year after returning to the capital star, Issi was accused of being a collaborator. Calypso secretly deported Isis back to Quioa, but the plane crashed during the deportation and Isis was killed at the age of twenty-one. After death, Isis accidentally fell into a gap in space and encountered the Lord of Events, witnessing the demise of mankind. In order to help the Lord of Events find out the cause of humankind's demise, Isis was reborn back to the day she was taken away from Quioa by Calypso. Isis, who died indirectly due to an imperial coup in her previous life, is not interested in saving humanity. He didn't care about the threat from the master of events who was so anxious. Isis discovered another pleasure. What did you say? Omega can't activate mecha? Then I must be the first person
