Synopsis
Dita, a frail boy, was abandoned in the forest in order to save the number of mouths to feed in the village. Helpless and alone, he's ok if death were to come soon. At such a time of horror, my childhood friend, Systra, comes to help only to have been followed by a demon. The demons are after her due to her ability to fulfil any wish in exchange for their life. With no hope, I decide to make a wish, a wish that Systra would be happy.

Thus, after both being killed, they are reincarnated in the same era once again. This time, whilst I try to make her happy, she dies unemployed. Reincarnation and again, death.

The cycle continues for 10 billion times, with each reincarnation I get stronger and increase the number of abilities I can use. I have overwhelming power. This came at a price as the 10 billionth reincarnation will be my final life. With my new found strength, I will endeavour to make Systra happy. I will eliminate all enemies that stand in her way. I will make sure to use my power to achieve her happiness no matter what!

My Thoughts
I would love to see this series licensed after reading the webnovel. A pretty strong action, adventure series where the MC has a clear goal in achieving Systra's happiness. The characters introduced so far all have motivations that drive them and the series itself has a number of different avenues it could explore that would give it even better potential.

Even if we assume that the average lifespan in their other world is 50 years, that would be 500 billion years. That’s thirty-six times the age of the universe.

How the hell could he retain memories of all that and stay sane?
