Found this by chance while browsing the internet..!

Manager, please delete this if it causes any issues...! They say it's a pro-Japanese collaborator scanner where you input your clan origin and last name to see information on independence patriots and collaborators...! I looked it up, and it was made by an individual developer. The search results are based on data from the Ministry of Patriots and Veterans Affairs and publicly available historical records!! However, it doesn't mean the person found is a direct ancestor! Even with the same clan origin, there are various branches and lineages! I tried it for fun, and it's quite fascinating..! lol What a strange and wonderful world with all sorts of things..!
