to clarify on the ova one chart. obviously we all know what characters premiered in ova 1. the ones that look out of place are linked to the ova 1 characters. for example seto and noike are there as variations of kagato. kei is a variation of zero who eventually ends up fused with ryoko. so i put them all on the same chart because it made a nice rectangle and because it let me show the association on one chart.
note: amane's brother doesnt exist. and it was his brothers fiance... and also that was a mistranslated dubline thanks funimation... i need to edit that one out and i also forgot kaneaki hirata... but busy at the moment
There's still more to come...
