I'm wondering how Font/Ruins of Alph will turn out considering the Hiroshima theories
I wouldn't put too much stock in those "theories". There's a much better candidate: Izumo. Its name resembles the Japanese word 泉 izumi meaning "spring" or "fountain" (i.e. "font"), and it's known for Izumo-taisha, the oldest Shinto shrine in Japan.
The rival in Red and Blue is called Green. Gary is some character from a lame cartoon.
