只剩下雪白的灰

Complete Luka's companion mission. Requires reaching TL 34 and completing the story mission "Silent Galaxy".

This is a reference to the Japanese manga “Ashita no Joe”. The Chinese title for this achievement is “All that remains is pure white ash.”, which is something Joe tells Noriko when she tries to talk him out of boxing. “It may be for a moment, but my fire roars up so bright and hot, it’s almost blinding. And then, all that remains is pure white ash.” It goes with Luka using boxing as his preferred battle method. - Credit: Raiden
