Yo birthday anon here! I was just looking into the Asuka dates and while Kreutz has like... a few options, Doppelkreuz/R#'s birthday has some more concrete possible inspirations. Namely he shares a birthday with Martin Luther, but also with radio personality George Fenneman. These are just some possible connections— I tend to notice some birthday choices are less obvious than others, so these are just possible suggestions. I will say November 10th is a bit busy historically (October 1st was worse so I gave up halfway). It also bleeds into events like the fall of the Berlin Wall *which did happen technically on the 9th but followed well into the 10th (looking for WWI and WWII related dates and any preceding + following conflicts narrows it down A LOT— especially considering Daisuke's messaging behind GG as a series). If I find anything for regular Asuka I will be sure to send it your way.
