Scientist Rui Kamishiro - Alien Tsukasa

Rui was a scientist, and his routine was simple: go to work, then return to his solitary home. In truth, the solitude didn't bother him—or at least, that's what he told himself.

One day, while stepping into his backyard for some fresh air, he stumbled upon a small blob. It was a blue, sticky little thing—complete with ears and a tail—and undeniably adorable. Rui could hardly believe his eyes. Had he just discovered an alien?

Over the next few days, Rui learned that the creature was a shapeshifter—and a rather clever one at that. It could mimic a human form, though it still retained its ears, tail, and patches of sticky substance clinging to its body. It also learned to speak, and the moment it did, it made its intentions crystal clear.

His name was Tsukasa. He was the prince of an alien race, and he had come to conquer Earth—even if he was far too tiny and adorable for such a task. Besides, Rui couldn't just let a discovery of this magnitude wander around freely. Who knew what other scientists might do if they found him? So, under the guise of 'teaching him more about humans and supporting his quest for world domination,' Rui managed to keep Tsukasa safely within the confines of his home.

That afternoon, while Rui was cooking, Tsukasa wandered over, watching him with obvious curiosity.

"Hm? Do you want some, Tsukasa-kun?" Rui asked kindly.
