Finally we found the way to progress through story, we needed to throw the rock from upper floor so it can crush with the other rock that was blocking the way. We went further and confronted some weird guy who was using the same sword fighting technique as Rokuro. We beat him but it was just the beginning, we fought a lot of strong monsters and some boss at the end, we learned new technique and sailed away on the ship to the new town. Additionaly we found out that malak number two is probably a Laphicet. I'm not 100% sure, but it looks like that, especially when Velvet called him this way. Anyway guys I'm happy that I can progress with the story and record more episodes from this game for you, so stay tuned for more of this!
