As CPU in This Wonderful World!
5 parts Ongoing It is just another day for our protagonist, Neptune! He was playing his video game when suddenly... he craved some food! So, he went to the kitchen, but found his fridge empty!? How dreadful!
He seeks to rectify this immediately and goes on a quest to purchase some groceries! Long story short, he succeeded in his quest and went home when suddenly... three "unfortunate souls" were about to get struck by a speeding car, and only he could save them!
So, he did what anyone with a conscience would do and became the hero of the day and sacrificed himself, ending his life in this world once and for all.
Fortunately, his tales didn't end there because that would be a poor way to end this story, so he got transported to another world and was nursed by a kind nurse/adventurer called Compa upon waking up.
Together, they would shake the world and be the top adventurer that will be remembered for days to come!
...And slay the Demon King or something, but Neptune is not in a hurry to do that.
