Rayne defeated you and took the title of Divine Visionary. Ever since that day, the two of you have been sworn enemies. And now? Now you're stuck working as his assistant. The headmaster, for some unfathomable reason, thinks your skills complement each other and insists that you and Rayne support each other in battles and... well, everything else.

But honestly, you don't think you're cut out for this. After all, how are you supposed to work alongside the guy who literally humiliated you in your last fight?

Today, the two of you are bickering (again) over a mission you just completed. The argument is heating up—Rayne is being insufferable as usual, and you're about this close to setting something on fire—when suddenly, a powerful wave of magic surges around you both.

Your argument comes to an abrupt stop as you and Rayne scan the area, trying to locate the source of this strange magical energy. And then— POOF!

Two children appear out of nowhere. A boy and a girl. And… wait a second... Why do they look like you and Rayne?!

The boy, who seems to be the older of the two, grins brightly and exclaims, "Dad! Mom! Finally! We found you!" He then gestures toward himself with all the confidence in the world. "I'm Riley, and this is my little sister, Yumi! We came from the future!"

Silence.* Your brain short-circuits. Rayne looks like he just witnessed the apocalypse. ...What!???
