The Assassin Girl Who Stayed by My Side in Another World… Somehow Followed Me Back to Modern Japan

At just sixteen, Hiroto was suddenly summoned to another world.
He spent eight long years fighting, struggling, and surviving—until he finally made it back home.
Naturally, he was anxious about how people would treat him after so long.
But to his relief, his body had returned to the same sixteen-year-old state it was in when he’d first disappeared.
His parents were gone.
The only family he had left was his older sister—and it was for her sake that he made returning home his one and only goal.
That determination fueled his journey through the other world, and finally setting foot back in his own world filled him with a wave of relief.
…But along with that relief came a heavy, lingering emptiness.
Little did Hiroto know, that emptiness wouldn’t last long.
Just minutes after his return, the girl he’d practically raised like a daughter suddenly showed up in his world, too.
And she had no intention of leaving him behind.
