i was reading this manga but i had to format my pc :/ lost it in the format and cant remember the name... hope you guys can help me ;/

it's something like battle royale... it's about some people who have animal dna implanted on their bodys and acquired these animals abilities... each time they kill someone and feed on their enemies body they acquire the enemies dna along with their powers.
the last one remaining can enter the "ark" but no one know what is this "ark" yet

sorry for the bad english but i found the manga interesting (read only 3 chapters) i only found it on one site to download... along with more 2 mangas (one i think the name was monster hunter...) but i cant seen to find the site nor these mangas anymore (the last time i found it was on google T.T)

ps: first post here already requesting for something >.>
