Make My Day (メイク・マイ・デイ, Meiku Mai Dei) is the twelfth and final episode of the anime series Full Metal Panic! Invisible Victory.
As Sousuke escapes from Kalinin's ambush, Leonard prepares to leave with Chidori, who realizes that Sousuke is coming to her rescue and refuses to cooperate. Leonard then gives her a chance to shoot him and escape, but she falters. However, once he attempts to take back his weapon, Chidori accidentally shoots him. Kalinin then takes Chidori and the wounded Leonard with him and they leave the island by helicopter, with Sousuke arriving at the scene just to see her being taken away. A disheartened Sousuke is captured by the enemy when Wraith appears to rescue him and give him the ARX-8 Laevatein, which he uses to dispatch the remaining enemies with ease. At the helicopter, Chidori steals a gun and demands Kalinin to return, and when he refuses, threatens to kill herself, convincing him to at least let her contact Sousuke by radio. Willing to convince Sousuke to forget about her at first, Chidori has a change of mind and asks him to rescue her no matter what instead, and Sousuke returns to the Tuatha de Danaan, where he is welcomed back by his friends from Mithril.
