I am the Honoured One (Gojo in MHA/BNHA)

At the dawn of Quirks one person would be born with a power special manipulation quirk, known as Limitless. This quirk was a cannon in the dark if not for their other quirk, a powerful perception quirk, known as Six Eyes, allowing them to both channel his Limitless one and allowed him to have sight six times as powerful as that of a normal human. What this person did is unknown beyond the fact they started a clan of their own, the Gojo clan. When their two children had been born one had inherited his Limitless, with their other inheriting Six eyes. Gradually through the years the family would inter breed to try and create a now Six Eyes + Limitless user after the first one died. Not one had been born until Satoru Gojo.

I'm pretty bad at writing so pointers appreciated!
