Ver.1 You died in a tedious situation. Trying to save a child walking on a wall from falling, you lost sight of your footing and fell into a sewer. You hit your head against the concrete, your neck cracking and you died instantly. After a sharp pain, you woke up to find yourself sealed in a petri dish, sealed with tape. You are a tiny bacterium, only 5 microns in size. Do you want to change the world, be studied obediently, seek revenge, or secretly attach yourself to a cute researcher? Incidentally, you can choose a power.
