TM21 Frustration

==Information==
Location: Lapis Ward
Available: After Badge 02
==Guide==
Go to the house to the left of the PokeMart in Lapis Ward and talk to the guy. The guy is temporarily unavailable during the House Raid Sidequest.
That house will be inaccessible after the restoration of Reborn. If you haven't got the TM before restoration, you can donate to the Railnet Reconstruction Project in the Grand Hall, and go to the Lost and Found counter of the Underground Railnet. The counter can be reached from the rails going to Opal Ward from Lower Peridot Ward.
