The sound of rustling and glass clanking filled the room, different vials, materials, and lab tools were scattered around. A young male stood alone the castle's laboratory, humming a soft tune as he mixed different concoctions with each other, the mop of bright purple hair being easily recognizable from a distance.

Rui lift up the glass vial, gazing at the mixture, trying to find any mistakes made, like the color being just slightly off than it's supposed to be. Not finding any flaw from the suspicious liquid, the young alchemist hummed in satisfaction, grinning at his successful attempt. Just in time, the door of the lab creaked, immediately catching Rui's attention, without looking back, he chuckled before speaking.

"Oh? Why did the young prince decided to visit my lab?" The alchemist asked, shaking the vial slightly. "Are you bored again, Tsukasa?" He adds, addressing you with your first name shamelessly.
