Welcome To Demon School! Nagisa-kun

Royal One

"BASTARD! TURN ME BACK, THIS INSTANT!" Kalego shouted

"But sensei~, you look cute though. Right, Opera?" I said

"Yes, Nagisa-sama. Kalego- kun looks rather adorable... He would be even more adorable if he wore this collar." Opera said with a very happy smile on his face as he was wagging his tail

"I'LL KILL YOU IF YOU DON'T CHANGE ME BACK!" Kalego shouted

"Don't do it, Nagisa-sama. He's trying to trick you." Opera said

"I'll change you, back sensei... Only if you give us, royal one." I said with a grin

"NEVER!" Kalego shouted

"Well... You made your choice. Opera, how about you take sensei for a nice outing? What do you say?" I asked

"I would gladly take you up on that offer, Nagisa-sama." Opera said

""WAIT!!! How about we make a deal instead?!" Kalego said as he was trying to get out of Opera's clutches

"Oh? I'm listening." I said

"If you really want, royal one. Then you need to get every faculty member's signature." Kalego said

"Deal! We can get it done in a week."

"In 3 days. I want every faculty member's signature here on this table in 3 days. If you don't accept th-"

I got up from my seat and stood on top of the table, unsummoned him, grabbed his hand and shook it and said "Deal!" unbeknownst to him and the others, I stole something from him while he was in shock

I got off the table and said "Don't back out on our deal, sensei~. Purge ya later." then made my way over to the door with my classmates copying my farewell to our sensei

"Nagisa-sama, you forgot something." I heard Opera said

Making me stop on my tracks and said "You're right! Sorry, Opera. Must have slipped my mind." I beckoned Clara to come over and ask for the thing

"No worries, Nagisa-sama. It happens to the best of us." Opera said as he was still holding a demon sized Kalego but not long after was now holding a snake sized Kalego

"Have fun on your outing, you two. I'll change you back to normal when the day ends, sensei~." I said waving goodbye

"Let's get Balam-kun to join us as well, Kalego-kun." Opera said with a smile on his face

"NAGISA!!!"

'Nagisa-kun in his evil cycle really is chaotic.' Every teacher who saw the events unfold all thought the same thing

-Timeskip-

After that whole ordeal in the teacher's faculty room. My classmates voiced out their thoughts about all of this. Mainly about how we would fail and we shouldn't even try

To which I quickly, gave out a speech. Now getting everyone's full support and cooperation

They asked what would be our first move to which I pulled out a notebook

"Wait! Isint that Kalego-sensei's notebook." Shanx asked

"Yeah. Stole it from him earlier. Now here's our game plan."

-3 days later-

"Here is all the signatures from the faculty, Kalego-sensei. Just as promised." Asmodeus said with a proud look on his face

Kalego looked around and asked "Where's Nagisa?"

"Nagisa-chi, went out to do something. He said he will come here later." Clara said
