NEED HELP RECOVERING LOST CONTENT

Hello everyone, something has been bothering me for an extremely long time. This in particular has to deal with a wealth of unused/scrapped content from the Sega Genesis classic; Monster World 4. This image includes 20 sheets that include things such as...

• Unused NPCs(LOTS of them)

• Items

• An entire playable character(Asha's male equivalent)

• Objects

• Attack effects

• Frames of NPCs who used to walk, but now just stand still

• A dark version of the queen

The sheet is below and can also be found here...

Monster World IV Lost Sheet

The name of the developer who is responsible for these as well as Asha's design is Maki Ohzora. I'm not sure what is the best way to go about getting these since these will never be used for anything or by anyone anytime soon. This would be a dream come true if I were able to get my hands on these in pixel perfect format.

If we are unable to contact her and/or find something that can clean these up, the last resort will be having to create or recreate them myself. Is there anyone who'd be willing to help me out with this? I'd greatly appreciate it.
