Introduction

"You want to know what relativity is? It's when you fall in love with someone, and time speeds up whenever you're around them - a conversation is cut too short and a glance becomes too fleeting. Hours seem like seconds, and you can never get enough of their presence. It's also when time slows down whenever you're apart from each other - an afternoon of separation feels like days of absence. Seconds seem like hours, and time comes to a grinding halt. That, my friend, is the phenomenon of relativity."

This is the story of how a normal girl saved a superhuman boy who saved a psychic girl who wanted to save the rotting world.
