- "What's the matter...? Are you simply going to watch? Are you forsaking him to save yourself? Death awaits him if you do nothing. Was your previous decision a mistake then? Very well...I have heeded your resolve. Vow to me. I am thou, thou art I...Thou who art willing to perform all sacrilegious acts for thine own justice! Call upon my name, and release thy rage! Show the strength of thy will to ascertain all on thine own, though thou be chained to Hell itself!"

- —Persona 5 compendium
is a fictional gentleman thief created by . He was known for targeting criminals or those who were much worse than himself, making him an anti-hero of sorts within his own stories. He might have been partly inspired by the french anarchist Marius Jacob.
Character designer Shigenori Soejima explained that Arsene was designed with an "old school vibe" in mind. Arsene's wings are meant to evoke the image of a thief's cape in the viewer's mind and represent the idea that a thief can go wherever he wants.
The protagonist obtains Arsene, his initial Persona, during his first confrontation with Shadow Kamoshida in his Palace, where Arsene personally teaches the protagonist how to fight during his first battle. He talks to the protagonist once again once he reaches the same point as the stories beginning at Niijima's Palace , facing off against Moloch once again. The Shujin Academy library has a book based on him called "The Great Thief" that boosts knowledge.
- In the game's prologue, Arsene's form is darkened, much like Izanagi's form is obscured in the fog when summoned during the protagonist's dream after he arrives in Inaba from Persona 4.
- Uniquely, Arsene is the only Persona to speak to the protagonist, should he be used in fusion, though this only occurs for the first time.
