Destroys everything he touches

This is a story I want to turn into a videogame, the character meets significant others in their life, but due to a curse, everyone they bond with will have their lives taken. With each passing, abilities from the friend will transfer to the main character of the story and at the end be reunited with all who passed, to fight one last time. You cherish the moments and grasp onto these memorable friends, making their death more impactful.
