The Four Keys (4つの鍵, Yotsu no Kagi)? are special weapons in Persona: Tsumi to Batsu.


The Four Keys are given to Kazumi Kiba and his friends as a means to combat the Reapers from Nymphéa. Described by Philemon as "anti-Grim Reaper items", the four keys can turn into swords that greatly increase a Persona's power and allows them to fight against the power of Grim Reapers.
