Loudmouthed martial artist Junpei Ryuzouji, elegant actress Airi Komiyama, and cheery but artillery-obsessed student Ritsuko Inoue all find themselves transported from their homeland of Japan to an unfamiliar, magical world. When the elven priestess Celcia Marieclaire casts the spell to send them home, she is interrupted, and the spell is broken into parts that scatter throughout the world.

Though they're not the smartest group, they make up for it with enthusiasm and their strong determination to get back to Japan. [Written by MAL Rewrite]
