This time together with his grandfather, the 5 families will learn what regret is.

This is getting interesting

How the hell did he get out, but his grandfather was trapped there for 20yrs? I hope it was the studio that made this decision and not the source material author...

haaaa

seal is undone because it was for trapping the dragon, when he is dead its undone itself as there is nothing to be sealed
logic

Man, I love this anime, but the constant barrage of azzholes gets exhausting!!!! Next season please!!!

lol yess barrage of buttholes

How was the barrier seal undone? Where is his grandfather? How much time has passed inside that cave?

when he killed the dragon the seal was broken I think

awww man, he came out early. I mean it was going well inside that volcano with his grandfather or whatever. They should have made it much longer

Did he just forgot about his grandpa and came outside alone

is this the last episode for this season?
