I found a site that has a lets-play with text and images and someone translated some parts that were different in japanese, its actually pretty good, and it all makes way more sense ! here is the talk with the witch (btw, the boy is named BOY and KID is the girl and BOSS is the sprite)
Elinise "Now then! I'll be sending you off to Lord Thanatos! Begone!"
KID "Dyluck! What did you to do him!?"
Elinise "Ka-ka-ka! For some reason, it's only that man that my magic won't work on... though work on him, I did. Lord Thanatos then ordered me to send him to the ancient ruins of Pandora!"
Elinise "The Magic Knight Lord under the Vandole Empire, working to destroy Pandora Kingdom from the inside!"
KID "I'll never forgive you!"
Elinise "Kekeke. Near all of the kingdom has already been stripped down to nothing but walking flesh. Once Lord Thanatos storms the castle from the southern ruins, the kingdom is finished. Now then! Let me feed you to my sweet little tiger chimera!"
Elinise "Hii--!! Don't hurt me!
I'm so sorry. Lately the herbs I use for my magic have all been rotting away... in exchange for stripping the minds of the people of Pandora, Thanatos supplied me with the herbs I needed. From now on I'll just be an ordinary old lady, and live my life here quietly... The young man I sent away ought to be in the southern ruins of Pandora. In the treasure boxes, I leave you what I won't need anymore. Please take them with you...
Hmm? The orb in the Underground Palace? Oh, I'm afraid if you don't have the magic of water, you can't melt the lava. I've already reverted to a normal old lady and can't wield such magical powers any longer..."
KID "I knew Dyluck had to be alive. Thank god..."
Luka "BOY? Can you hear me? Come to the Water Palace immediately!"
BOY "That was Sage Luka! What in the world's happened now? Guys, I have to go..."
KID "... I'm going with you! I'm so worried about Dyluck, but it looks like it's going to be impossible to save him on my own. I've decided to go with you two, but in return, you've got to help me save Dyluck."
BOSS "Sis! I'm with ya! I'm on board for the long haul. Leave it to me!"
it doesnt have ALL the text translated but, most of the important parts are, here the link to the site, on the bottom of each page is the translation of the important dialogs made by "Reverend Cheddar" the lets-play is also pretty funny btw : link
