Lumiose City Exploration (Part 2)

In Vert Plaza, battle the pink-haired woman, Punk Girl Lillian, who uses a Level 30 Krokorok (Dark/Ground).

Head down the alley and battle Beauty Aimee, who uses a Level 34 Fletchinder (Fire/Flying). After defeating her, you will receive a Destiny Knot.

Pass a cafe to your left to reach Beauty Aimee. This cafe is called Cafe Cyclone. Explore it and then leave.

Head back to Vert Plaza and go anti-clockwise to Jaune Plaza.

In Jaune Plaza, head down the alley toward the boulevard. Enter the open door on your right to find Trevor's house. Explore it and then head back outside.

Past Trevor's house, take the alley on the right to find Beauty Anais. Battle her; she uses a Level 34 Seadra (Water).

After defeating Beauty Anais, you will receive an Elixir. Continue following the alley to Hibernal Avenue.

In Hibernal Avenue, enter Cafe Kizuna next to the alley. There is nothing of importance here.

Across the street is a restaurant that is inaccessible until after the Elite Four.

Head toward the boulevard and find an alley to your left. Follow it around and find a path leading to Black Belt Killian. Battle him; he uses a Level 30 Machoke (Fighting).

Head back to the main part of the alley and follow it around to Rouge Plaza.

In Rouge Plaza, there are two buildings. The building opposite has nothing of interest, and Sushi High Roller is inaccessible until you 'become famous'.

Find the alley leading to the next Avenue and head down it. When it splits, take the right path to battle Punk Guy Faust, who uses a Level 30 Haunter (Ghost/Poison).

After defeating Faust, return to the split and take the other path to Autumnal Avenue.

In Autumnal Avenue, enter the Poké Ball Boutique to the left of the alley. Tell the man you like round things to receive a Luxury Ball. You can purchase various Poké Balls here: Quick Ball (1,000), Dive Ball (1,000), Timer Ball (1,000), Premier Ball (200), Heal Ball (300), Net Ball (1,000), Nest Ball (1,000), Dusk Ball (1,000), Repeat Ball (1,000), and Luxury Ball (1,000).

Next door is Restaurant Le Yeah, where you can dine and battle.

Across the road is Restaurant Pokémon-Amie.

Head toward the city center and enter the blue shop behind the taxi, the Juice Shoppe. Here you can combine berries for juices or get a premium juice.

Cross the road to the next alley anti-clockwise to find Lysandre's Cafe. Enter it.

Inside Lysandre's Cafe, Sycamore and Lysandre will speak with you. Lysandre will give you a King's Rock. You will then receive a Holo Clip from Trevor mentioning everyone is meeting at Route 14.

Head through the alley to Magenta Plaza.

In Magenta Plaza, visit the Pokémon Center to heal and stock up.

Head into Centrico Plaza, which is a shortcut to Route 14.
