Barking Up The Multiverse

All Alex Carter wanted wanted to do for Summer was stay home, prepare for his senior year of highschool and confess to Mia. Simple, right? Unfortunately, after his dog Max woke up one morning and chose chaos in form of a pebble-sized crystal that he found in his backyard, Alex's summer took a turn. A dramatic, multiversal turn. Every time Alex thinks he's grasping the slightest bit of normalcy, something even weirder happens-demon squirrels, Max turning into a boy, transmigrating, being isekai'd into different worlds, and oh yeah, a system that somehow threatens to erase his entire existence. Can Alex survive this wild adventure, or will he embrace the madness and just roll with the punches (and the portals)?.
