Stein didn't know the witch had even hit Spirit with the spell until he woke up the next morning. Both of them too tired to do anything amorous that night, they went to bed. Spirit stirred sleepily, rising from his current position in Stein's arms. He walked out to the kitchen, rubbing the back of his neck. He blinked, trying to work his slumber out if his eyes, and he opened the cabinets, looking for something that could serve as his breakfast. Dissatisfied with the selection he found, the weapon figured it would be better if he just did his morning grooming in the bathroom and hoped Stein cooked. So, he shuffled back to the bedroom, careful not to wake his sleeping lover, and went to the private bathroom. The battle last night had left him remotely unscathed, except for an odd feeling in his head, and he was hypersensitive to sounds. And he also felt like something was behind him, giving off wind as it moved. But, he wrote them off for a time when he weren't so sleepy. He yawned, closing his eyes and fumbling to find his toothbrush. Squirting a glob of blue paste onto it, he raised the minty bristles to his mouth and opened his eyes. A shriek made Stein fly to life, and rush into the bathroom.
"Spirit wha-" The doctor stopped dead in his speech. Spirit looked at him, horrified, and an amused grin spread across stein's face. Spirit, who had unknowingly gotten hit with the spell, (Which, it was now clear to Stein that he had, in fact.) Had become a neko. Two cat-like ears that were a shade darker than his hair were on his head, with shiny and soft-looking fur covering them. And knowing a bit about the creatures, Stein knew that Spirit now had a tail, which he assumed was the same color as his new ears. Stein chuckled and walked up to his mortified boyfriend, wrapping his arms around him and kissing his forehead, Still unable to look at the new attachments on the top of his head.
"Stein, that witch made me a neko! I have ears like a cat! And a tail! LIKE A CAT!" Spirit shouted, a crack in his voice that made the scientist laugh.
"It's okay, Senpai." Stein looked at the ears thoughtfully, giving the tip of one a tiny tweak with the tip of his finger. It twitched in response, and he became slightly immersed in a small experiment. He snapped near it, and they both reacted.
"There's a pinna response, so they're obviously functional." He said, and Spirit pouted.
" Stein…What am I going to do?" He whined, and then Stein gasped softly, and turned around, glancing at his clock. He turned around with a smirk, reaching up and giving one of Spirit's ears a scratch. Spirit made a soft humming noise similar to purring, and Stein smirked wider.
"Well, my dear pet, at the moment, we have to go to school." He said, and Spirit's face drained of color and almost comically, his ears pricked up and his tail stood on end behind him. His cheeks became a vibrant crimson.
"Wha-?"
