When you get to the Looker Bureau, Looker will say he wants you to be his assistant, after hearing of your jaunts with Team Flare and you being the Kalos Champion. However, he wishes to test your detective skills and so sends you out to Lumiose City in search of five special tickets, Looker Tickets. They are located as follows:

• Magenta Plaza: In the Pokémon Center
• Centrico Plaza: In the Gym
• Vernal Avenue: In the herb shop
• North Boulevard: In the hotel
• North Boulevard: In the Museum

Take the tickets back to Looker and the mission will be complete

Your next mission with Looker involves the investigation of the back alleys in South Boulevard. It seems various children have been playing there rather than attending to their studies, and the parents in the city are worried. Looker asks for you to go check it out.

When you reach the end of the alley, you meet a girl called Emma and her Espurr, Mimi. However, Espurr suddenly runs off through the alleys in North Boulevard, and so you have to go find it. After doing so, Looker offers to give Emma and Mimi a place to stay.

In this mission, when you visit Looker and Emma, a tourist will run into the building speaking a different language. Looker misunderstands here, but Emma can speak the language and you learn that a gang has been stealing people's Pokémon. Looker tasks you with hunting down this gang and defeating them.

This gang is found in Lumiose City's train station on North Boulevard. When defeated, Looker starts to talk about his overall mission, and how he has to go undercover, while Emma decides to look for part-time work in the city.

In this mission, you get informed of some vandalism that took place within the Lumiose Museum. It turns out someone has destroyed an important painting. Upon investigation, you start to hear talk of someone going around stealing people's PokéBalls straight out of their hands. Looker tasks you with investigating..

Upon investigation, you learn that these thefts have been happening near the back alleys in Northern Boulevard. Looker decides it's a good opportunity to set up a sting operation. However, each time you confront the person, they revert into a robotic appearance and escape. In the third attempt, Mimi the Espurr arrives and starts acting friendly to the robotic suit. Looker concludes that it must be Emma within the suit...

In this mission, Looker is away, claiming to be at the hospital, but Emma is at the Bureau and states that she was informed that there is someone who wishes to meet you at Hotel Richissime in North Boulevard. When you go there, you find the Elite Four member Malva is waiting for you. She says she has a message for you and Looker, but wishes to battle you first. Once you battle her, she will inform you that Xerosic is the man Looker has been in town hunting for, and that he can be found in Lysandre Labs

When in the labs, Malva will inform you of a special, hidden floor, that only Xerosic and his staff have access to. She manages to give you access to it. You have to navigate your way around the area, battling the Lumiose Game members who are there for part-time work. When in the final room, you get to read up on Xerosic's notes about the suit, which is when he, confirming it is Emma who has no control over her abilities, sends it to attack you. You have to defeat her four times in order to proceed.

After defeating her, she will become free of the suit and Xerosic is astonished that his research failed to overcome the human mind. He will concede his defeat and agrees to go with Looker.

When you arrive at the Looker Bureau, you will find Emma who has found a note from Looker which reveals who he actually is and that he is leaving town. Emma is upset and rushes off to look for Looker. Your task is to help her find him. First, looking in the museum, you will find someone who notes that he was seen going to the Lysandre Café in Magenta Plaza. Go there and you find Looker and Xerosic.

Xerosic again concedes his defeat, giving Emma the suit to use as her own, as well as letting her keep the Pokémon he loaned her. Looker also gives her full control of the Looker Bureau before he leaves.
