Log Horizons season 3 also shown as season2 ep 1 but it's season 3 ep1 since I compared the season2 and the new ep and they are different so named the sub titled log horizons season 3 or Log Horizon: Entaku Houkai is out with 1st ep and the second due on the 20 and it's in the wild on the web now ep 1 if you want to watch it though it seems not the same but it's been 6 years almost since the last season 2 aired so that is to be expected.
