My brother is dead.
So, I decided to inherit his wife.

Let's try again to write some more convenient pathological attacks to find out the feel.
First person, main attack, attack with unusual brain circuit × male god, abo background, but will not give birth to children. CP is Leon (beta) × Ryan (omega???), With a slightly less important suspense component. Except for some protagonists who can operate mechas, there is no black technology, and there will be no battle scenes. It is just a story about a younger brother acting as an amateur detective on a whim and falling in love. I hope everyone will like it.
Purpose: Bravely search for the truth
