Item from Re:Zero by Tappei Nagatsuki
The Authority of Greed rewritten by Subaru's soul — instead of taking from others, it lets him share their burdens. He absorbs his allies' pain, injuries, and exhaustion into himself. Greed, inverted into selflessness.
Cor Leonis is what happens when the Witch Factor of Greed encounters someone whose fundamental nature is the opposite of greed. Where Regulus Corneas used the Greed Authority to make himself untouchable — freezing his own time to become invulnerable — Subaru's version manifests as radical empathy weaponized: the ability to sense his allies' conditions and literally absorb their suffering into his own body. In practice, Cor Leonis allows Subaru to take on the wounds, fatigue, poison, and pain of anyone he's bonded with. Their injuries heal; his multiply. Their exhaustion lifts; he can barely stand. It's the most Subaru power imaginable — a tactical ability that works by volunteering for more suffering. The Authority also grants him awareness of his allies' positions and emotional states, making him an ideal coordinator in the multi-front battles that Re:Zero loves. Cor Leonis doesn't make Subaru stronger. It makes everyone around him stronger by making him weaker. It is, in every sense, a hero's power disguised as a martyr's curse.
