Mementos Requests are a mechanic in Persona 5 and Persona 5 Royal.
The requests in Persona 5 are missions taking place in Mementos, some of which are needed to progress Confidant links. After finding out a target's name in the real world, the protagonist must find and defeat the target's Shadow in Mementos in a boss fight to make the target have a change of heart.
The first mission, "Beware the Clingy Ex-boyfriend" acts as a tutorial mission while other missions are received through Yuuki Mishima's chat messages, certain Confidants or certain part time jobs. Due to plot reasons, the protagonist can only access and complete missions up until December 23rd.
Several Mementos bosses are susceptible to Confusion. This weakness is one of the fastest methods to obtain money in Persona 5. A boss confused with the spell Pulinpa by a Persona with Confuse Boost and a high Luck value can drop up to 150,000 yen per turn at around a Luck level of 70.
Some of these targets can be seen or interacted with in the overworld and outside of cutscenes. Yumeko Mogami can be seen recording and stalking a student at Shujin Academy, Yohei Kiritani appears as an unsuspecting beggar at the Shibuya Station and Shiro Asakura can be seen harassing a woman in Shinjuku before and after his heist request.
Missions marked with an asterisk contribute to the progression of the Moon Confidant.

†The first mission is not optional as it ties directly into the Madarame arc.
†"Winners Don't Use Cheats" is required to unlock the Tower Confidant and the target cannot be defeated until the Confidant is established. All attacks will simply miss it, in which the battle will automatically end in a few turns.
†While the final mission can be accessed as early as December 3rd, the protagonist must finish Shido's Palace to unlock it.
