Island Survival: My Ship Can Transform into a Shipgirl

(Updates paused) Don’t Forget Me is the prequel to this novel. This story takes place after the prequel’s bad ending, so it’s recommended that you finish the prequel before reading this one. All of humanity descends upon islands to fight for survival. Everyone can have two talents: one chosen and one random. He gains the Fusion talent and the Life Cube. When the two combine, what does it mean for my ship to turn into a ship girl?
