In Hell, Tobe has been tortured for 300 years now, and his spirited desire to be free doesn't show any signs of fading. Tobe is given a final chance to make up for all the sins he committed while alive on Earth: he must use the legendary sword, Togari, to defeat and destroy 108 Sins in 108 days.

So Tobe is sent to modern-day Japan, and even though things aren't exactly like the Japan he remembers, he must defeat the 108 Sins in time to be free again.
