So I grinded away to the final battle with whats his face. I was wondering if there was a CG room anywhere post completion, and how to transfer the save to Ep2 if that is even a thing
There's instructions in one of the japanese .txt files.
Long Story short, just copy over the entire save-directory to be safe.
Edit:
Some updates now that I finished the game on v2.8.
To get to the final *hidden* dungeon, you need to get 4 helmet "key items" from defeating the warlord bosses. These warlords are the ones behind the door behind the guide-managed dungeon place.
After you get 4, use the helmet item in your key items, and it will set your teleport ring's saved-location to a hidden dungeon. Use the teleport ring to get to the hidden dungeon.
You will fight Lelyasu as the boss of this dungeon during the day, and Nobunaga as the boss during the night. After you beat them, they can spawn in regular mobs in the final hidden dungeon (as can any of the warlord bosses from the guide-managed dungeon).
To get Rank S adventurer rating, you need at least 3 people in your party with Rank A adventurer rating. I have no idea if there might be any bugs with it.
I hope the author took the opportunity to add "additional" events as *rewards* for carrying over saves (beyond just the items and levels). But I highly doubt that.
Also, I am still disappointed the author decided to remove the Combat Rape scenes, and have only a "generic" one during combat.
EDIT2:
Fertility Seeds is a currency that carries over when you transfers save files, without you having to load in the characters from the previous save.
Given that there were a substantial number of bugs that were reported regarding the transferring of saves, it's probably safer to not *transfer in* the character until you finish the game and get to A-class adventurer.
