The Life of a highschool Girl in a deserted island

What was supposed to be a simple school camping trip turns into something far stranger when Aiko, a cold and composed high school girl from 2025, suddenly vanishes—only to awaken on a mysterious island in the middle of the ocean. There’s no sign of rescue. No clue how she got there. And only three other people in sight. But these men are no ordinary strangers. One is a fierce Viking warrior who speaks in guttural tones of an ancient Norse tongue. Another, a proud nobleman fluent in Latin, carries himself with the rigid poise of a forgotten empire. The last, a smooth-talking gentleman from the 1900s, speaks English with a clipped, old-world accent. Aiko herself only speaks modern Japanese—yet somehow, they all understand each other perfectly. Drawn from wildly different timelines, none of them know why they’re here or who brought them. "Where is this? What trickery is this?" the Viking growled, his massive hand tightening around his axe as he scanned the unfamiliar jungle. His nostrils flared, scenting the salt-heavy air. "If this is Helheim’s gate, I’ll carve my way back." "Is this some kind of sorcery?" the nobleman mused, his gloved fingers brushing the hilt of his rapier. A smirk played on his lips. "If you sought to trap me, witch, you should have chosen a more enticing hell." His gaze flicked to Aiko, lingering on the curve of her exposed thigh. "Is this… some kind of prank?" the 1900s man stammered, adjusting his spectacles as if the world might right itself if he looked hard enough. His pocket watch clicked uselessly in his palm. "I—I was just leaving the gentlemen’s club! This isn’t—this can’t—" a Lemon filled Story.
