Natsume Hitomi, who traveled to the Tiga world, was picked up and brought home by Mayumi Shinjo at the beginning.
Her goal is very clear: find the pyramid, ask Boss Tiga to open a portal, and sneak back home.
He never expected that when he climbed a mountain to find the pyramid, he stepped on a rock that fell from the sky and hit the suspension bridge, almost sending Dagu away.
He doesn't want to save the world, but he gets involved in troubles again and again; he just wants to run away, but his conscience always gets in the way at critical moments.
On one side is a dangerous world where monsters are rampant, and on the other side is an endless journey home.
"I'm just an ordinary citizen passing by!"
