O-opera Senpai!

~Chapter 1~ The stay

I know Opera is non-binary and that their gender is a mystery and might most likely be a girl (I'm just guessing!😖) but I hope you don't mind me making them a guy for this Fic.

3rd POV
As Kalego flew to his last students place, he noticed how dark it was starting to get, it was 6:43 PM. Since tomorrow was going to be a school day he wanted to hurry up with the visits as soon as he can.

Now in front of his students mansion, he knocked on the door. A few seconds passed and the door opened to reveal his student Iruma smiling at him. "Welcome! Kalego-sensei!" "Where's that airhead of a principal at? I want to get this over with" kalego said as he was let in and following behind Iruma. Iruma was the last student of the night that he needed to visit and he needed to talk to his guardian about his progress in class. Kalego wanted to get this over quickly because he knew a certain someone was most definitely going to be there.

As they were still at the entrance, Kalego walked up behind Iruma and lifted him up as he requested Iruma to lead the way. Once kalego finished his sentence he felt a presence behind him. "Hello there Kalego-Kun" as soon as kalego heard that voice he reacted quickly and turned around. In front of him stood that certain person he feared to see. "OPERA-SENPAI!!" Kalego yelled as he let Iruma go and quickly backed away from the cat demon in front of him. "Indeed, it is I, Opera-senpai" the cat demon now in front of him named Opera waved at kalego as he said that. "The very same Opera-senpai you had so much fun with at school" Opera was now looming over Kalego. both hands raised and moving up and down slowly as they opened and closed there fingers. Kalego then pulled Iruma back up and held him as a shield to block Opera from getting any closer.

(The same thing goes as the anime/manga. I've read the manga and I watched the anime. I also apologize if I make some errors and that it's not the same as what the characters say in the manga and anime.)

"Alright, now that I'm done I'll be heading out now" Kalego said as he picked up the gifts given to him by his students. "Oh are you not staying the night?" Opera appeared beside him with a basket full of things needed for a night stay. "Hah!? I'm not staying a night at this place!" Kalego replied with an irritated expression. "Iruma-sama doesn't mind you staying the night, right Iruma-sama?" "H-hai!"
With a sigh kalego decided to give in and stay the night. He already had a major headache so he didn't want to make it even worse than it already was.

After eating dinner with his students family. It was really strange to have dinner with his student, the chair demon, and his senpai. It was kind of nice but he wouldn't admit that out loud and he just wanted to go back home and tend to his cacti's but here he was at his students place, staying the night. After dinner was done Opera led kalego to the guest room they had. It was a decent size for a guest room and a three quarter bathroom was beside the guest bedroom. As Opera led Kalego inside the guest room, kalego placed his gifts from his students beside the bed. As he did that he saw opera walking towards him with something in his hands. "Here, change into these clothes, they're going to be a bit big but it should do" Opera said as he handed the clothes to Kalego. Kalego decided to just nod and leave to the bathroom.

A few minutes later

Kalego was now in a white button up that was loose enough to let him breath, it was loose enough to the point it was not squeezing his chest and shoulders. a few buttons were left unbuttoned just in case it would get hot. The pants he wore were also white and they were also loose enough not squeeze his lower half of his body down to his ankle. It was quite comfortable but again Kalego wouldn't admit that out loud. He also had slippers given to him; they were white and they were puffy but not fluffy. As kalego was done changing he brushed his teeth and washed up his face then fixed his hair. Once Kalego was done he opened the bathroom door, and walked out towards the guest room he was staying in. as he got there he saw opera laying on the guest bed. Opera was stretching his arms and legs in a snow angel movement.
"Opera-senpai!? why are you on my bed!?" Kalego questioned as he exclaimed, as kalego  was now beside the bed. "Oh hello Kalego-kun, you took quite a while, so I decided to warm the bed for you" Opera greeted as he sat back up and faced kalego with a straight face as his ears twitched happily. As kalego saw this, his right eye twitched in annoyance, but he knew he shouldn't try fighting his senpai. With a sigh he just nodded his head and asked opera to leave. Opera just nodded and left. He was going to tease Kalego a lot later on tonight.
