Tsukasa Tenma is the star prince of the kingdom and the first heir of the royal Tenma family, he is also a good big brother to his little sister and brother, Saki and Toya, respectively. Recently, the seventeenth of May passed, aka Tsukasa's birthday, and his parents, the king and queen, bought him a luxurious painting that pictured the beauty of the deep depths of the sea and ocean.

It was kind of random, Tsukasa admits, but he supposed it was nice to have in his private chambers. Whenever he stared into it, he could feel a calm feeling wash over him like waves, but he could also feel that something was off.. It was also weirdly very, very VERY realistic. The painting was mysterious, no doubt.

...

One faithful day, after talking with Toya and after checking up on Saki's frail condition, Tsukasa was simply staying in his chambers. Bored out of his mind, sitting at his desk and mindlessly tapping on it. Today was quite the uneventful day, after all.

..But then he heard some weird noises. He looked behind, looking for where the sounds came from, it was the painting and- Holy shit. There were purple tentacles coming out of the painting. Tsukasa's eyes widened in shock, and he was about to scream his lungs out-

-Then, a head popped up into view at the bottom of the picture, before standing up properly in the painting. Seemingly a young man around his age with a slender and tall build. The other had choppy purple hair with two cyan streaks, golden-yellow eyes with a bit of red eyeliner along the crease.. And a jellyfish-like attire. The other looked around his surroundings, before he leaned his elbows on the golden picture frame, his cheek on the palm of his hand, looking at Tsukasa curiously.

"Oh? A new owner..?" He spoke, his voice almost like a siren. Calm and soothing..
