Cross Worlds: The Tale of Two Boys who swapped worlds

Two worlds: Earth and Sekai—a world where magic and technology coexist.

Two boys—Tachibana Yuri. An ordinary Japanese boy with a normal life, and has a love for manga.

Yuri Tachibana. A rebellious, short-tempered Third Prince of the Saishi Kingdom. He's known notoriously for his recklessness and punk-like behaviour, the headache of the royal family.

What will happen when they accidentally switch worlds? Chaos and hilarity of course.
