The Binding Of Wrath

After fighting and brutally dying in World War 3, Isaac Blaze gets reincarnated into a fantasy world with magic, curses, monsters, and many more. The world was everything but a happy place. After many years of living an empty and pointless life in this new world, Blaze decides to give up on everything and open a tavern where he spends all-day drinking alcohol. Blaze no longer cares about anything and decides to mentally isolate himself from everyone, until a bunch of annoying teenagers barged into his tavern and disturbed his peaceful drinking session.
