Prologue

Izuku was born with a quirk where his skin was made out of diamonds. His quirk was called gem magic. The amount of gems he had was how strong his magic was.

Izuku never went to UA instead he went to online school and finished and got a degree in elementary education. This is also set about 10-ish years after class 1-A was 15/16. So they're all about 24/25/26 now.

Emerald - he can control the element of earth
Ruby - he can control fire and hot temperatures
