As a human, I should be miles away from any large shifter event. Especially the annual Mate Hunt.A hunt for mates. Doesn't that sound barbaric? Yeah, it's as bad as it sounds.Several packs in the area gather as their newly minted adult wolves shift. Females are let into the woods first and are given an hour's head start, just before sundown. Then it's time for the males, ostensibly thrown out to hunt down the scent of their fated (or chosen) mates.It isn't an event for the faint of heart, and it's definitely no place for someone who can't shift. So why the fuck am I here, running my little human heart out, chased by what sounds like an entire pack of wolves? Great question.

“Legend had it that in the deepest part of the oldest galaxy, there was a door as red as blood and fire.

The Door of Constellation that overlooked everything would warn the sky and earth, sending darkness back to where it belonged.”

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
