There's Hetalia Archives but I need a Hetalia episode to chapter (+ musicals, drama CDs, etc.) converter badly. Ugh, I don't think I could do it; there are so much media material.

Note: I added episode lists and some synopsis/summary for Hetalia Axis Powers and Hetalia World Series (as well as some of the extras) because the Hetalia Axis Powers Fan Disc was confusing. Those with ⬅️ are part of the fan disc.

✔️。
