The Strongest Esper and The Strongest Psychic had met but in a rather odd particular way. They were transported to the world of My Hero Academia. As of now, they're married and they gave birth to Y/N. A son of both power of an esper and a psychic.

The era of heroes is over, with the hero association almost extinct and the espers now living in secrecy, the talented son of a legendary esper couple starts attending a school which is under the control of the devils. Raised with the mentality that all demons and evil spirits are enemies and carrying an enormous power that is still unknow to most devils, how will he fit in this new life?
