To those who are unfamiliar with the Waifu Catalogue, let me explain it.
It's a very broad CYOA(Choose Your Own Adventure)
Basically, the Contractor can capture and sell fictional characters to this Evil Omniversal Slaving Company. They can do missions too.
It grew over the years, with new content being added. Because of the whole waifu idea, the Cyoa is lewd-centric, with corruptive powers that encourage Harem.
You can basically go to any world, be anyone, having any waifu, or any power if you have enough credits.
For more information just search it up. The document is Huuuge.
But you can play in the Interactive Mode. Very easy and intuitive to use...
Have fun making some builds, like being Superman in Marvel with the Template of Flash.
Yep, it's easy to be OP.
