One Sin and Hundreds of Good Deeds
One Sin and Hundreds of Good Deeds (O-03-03) is a non-fightable ZAYIN-class Abnormality, that was originally contained at L Corp. Headquarters.

It is the source of the E.G.O Penitence.
Appearance
One Sin and Hundreds of Good Deeds has the appearance of a levitating cross, seemingly melded with a skull, both of which are bound tightly together by a thorn crown. A faint glow can be seen emanating from it. It can sometimes be heard chanting while in its containment unit, usually when an agent is working on it.
