Bringing you back

A message came 7 years after the sudden appearance of towers, at Lya's lowest point.

"Whoever completes all 51 towers in 730 days and acquires all their treasures will get to wish for anything their heart desires twice, no matter what the wish may be and the cost to fulfill it."

No tower had ever been completed even once and Lya was the lowest rank of them all, Z-rank, there was no way she could beat even half a tower, but if she could bring Ollie back, then the impossible might be more possible than one might seem.

But she wasn't the only one to receive that message, the whole world did, the rewards tempted everybody, and everybody had something their heart desired. It's a race against the clock, nobody knows what will happen after 730 days and if even beating the towers is possible, all they know is that the rewards are too valuable so much so that taking the risk of taking your own life seems too trivial.

Let the best ranker win-
