Saiyan of Earth (Male Reader X DB X Medaka Box X RWBY X MHA Harem!)

This story takes place in an alternate universe, but is still a spinoff to the Our Guild Story! Son (Y/N) is a Saiyan who was sent to Earth by his father, Bardock, and his mother, Gine, to survive due to the destruction of their homeworld. He was raised by an old man named Gohan, and eventually, at the age of 10, he went out to see the world after an encounter with a human girl named Bulma Briefs. During the span of 6 long years, he had grown into a teenage martial artist and had made many friends over a long 3-year journey in between. But when he learns about his true lineage, now he faces extraterrestrial threats, supervillains, abnormal humans, androids, demons, gods, and even a vicious space wizard!
