In Megami Ibunroku Persona, Evil Smile is an enemy-exclusive Energy Drain skill. When used on a foe, it will inflict them with the Paralysis status ailment, and when it hits a foe that's already paralyzed, it'll reduce their level by 1. The foe doesn't need to have been paralyzed by this skill for the level-lowering effect to trigger and multiple levels can be lost in one fight. Not only will the level be reduced, so will the affected character's stats. The game keeps track of which stats each point granted on level up was spent on, and will revert those changes. The Tetraja skill will protect against the level-lowering aspect of this skill.
