The World of Factions TWOF

Another Isekai? But wait.
Yuto Sakigami is sent into another world where people must fend for their lives and risk dying--- to other humans. In this world, the concept of "friends" is thrown out as everyone around you may be harboring malicious intent. With no clue as to how he arrived here, Yuto Sakigami must fend for his life as he tries to search for a way back to his old world.
