Hiroshima Chronicles is an open project for everyone. Basically, it's just stories about people living inside or near atomic bombing city. The timescale can be as you please. Hiroshima Chronicles are not historically accurate. It's character and milieu are all fictional.
If you wish to make a part in this chronicles, you don't need to ask my permission, just go for it :)
But it would be nice, if I would know about it.
If you are curious for this project, but still lack of ideas for the flash, I have plenty to share.
