How do I unlock rank 4 parts for the Gottrlatan?
Unlock and clear the “A Dangerous Young Lady” Extra Mission. To unlock the mission, you must max out your relationship with Katejina Loos and read the terminal message received after clearing the “Operation Giant Roller” Friendship Mission. To unlock “Operation Giant Roller”, you must complete at least stage 1 of the “To the Victor” Friendship Missions for the League Militaire and choose to help Katejina when reading the terminal message received immediately afterwards. Note that the “A Dangerous Young Lady” Extra Mission is restricted to single-player only and requires that you pilot the V2 Gundam.
