Rui's fallen sick, and Tsukasa's instincts kick in.

The people of land and people of the sea were always at conflict. If one were to step onto the territory of the other, blood would surely be spilled. This made sea travels very hard, and the ruler and king of one of the land kingdoms — Tsukasa Tenma — knew that, though his bravery got the best of hi

Tsukasa walked right behind him, jogging to catch up to Kamishiro. The roads were too empty for his liking. “Rogue vampires don’t attack people in pairs, we should be safe.” Tsukasa said. He knew the way to the plaza as well, he didn’t need to be guided.“Some vampires are too feral,” Kamishiro said,

Everything has been going well so far. Wonderlands x Showtime has taken off decently, and Rui and Tsukasa have still been meeting up in between college lectures, still passionate about their show discussions. Rui couldn’t ask for anything more, for sure…“Tsukasa-kun, what did you just say?”“I said,
