The next day, Iori had gone off to school. They had explained the Tsumugi that there was a Netherworld that was a literal school for demons. It was an ever expanding school and the Overlord acted as the Dean. There was 4 separated buildings for Freshmen, Sophomores, Juniors and Seniors. Where the Junior building was, no one knew.

Iori waited by the entrance of the academy since he didn't see Tamaki outside of the school like he usually was whenever he had to drag him to school. Normally because Sogo had thrown him through the dimensional gate by then so he'd have no choice. After a few minutes of waiting he saw Sogo dragging Tamaki by his tail into the academy.

"So you had to drag him to school this time Osaka-san?" Iori began, he wanted to start the conversation as a casual one.

"Mhm, as usual he's reluctant to go though. You could learn some useful things from school Tamaki-kun. Look at Iori-kun, he works really hard and studies even if it's an unusual thing for demons to do"

"But I don't wanna go to school, no one else does except the delinquents" Tamaki whined.

"Tamaki-kun.." Sogo glared at him.

"Alright alright! But don't expect me to start being like Iorin.."

"As long as you do some work!"

As the two continued to bicker about Tamaki going to school and trying to actually learn, Iori decided to cough to draw their attention. To which Sogo immediately apologized. He had learned that Sogo wasn't exactly like Yamato described him. Honestly he was a little misunderstood.

Sogo was something like a mad doctor, he couldn't help but try to use people as experiments when he got a chance. Tamaki was teaching him to stop doing that though as it was extremely disturbing and scary. Overall though he was a kind hearted person and cared dearly for Tamaki. They both had a good relationship with Iori.

"Osaka-san may I ask you something?"

"Huh? What is it? Has Tamaki-kun been causing trouble?" 

"Why do you immediately assume it's about me?!" Tamaki immediately questioned.

"No, it's about you actually, I was wondering about where you live" 

"Mm? Do you want to come by a visit or something Iori-kun? I live in the same Netherworld as you, just far away from the towns. Tamaki-kun can show you where after school" 

"I see, thank you. But if it's alright with you, may I bring Nii-san and our friends? They'd like to meet you both" Iori asked. It'd be better to get his permission instead of surprising him with a group of people he didn't know, aside from Yamato.

"That's fine, now I'll be heading back, be good Tamaki-kun"

Tamaki uttered an 'okay' as Sogo walked out of the academy to head back to his home. At that moment Iori noticed it was time for classes to begin and instructed Tamaki to head to class with him. Of course the werewolf didn't hesitate much to follow Iori to the classroom. He had gotten in trouble a lot of times with Sogo after he found out about that.

The only demons in their classes we always delinquents, except for him since he was always forced to. He seriously didn't understand why Sogo wanted him to go to school. Probably because he himself went through school. 

"Iorin...this is boring.."

"Class just began and you're bored?"

"The teacher doesn't even want to be here! They're not even teaching the right subject!"

"You'll still learn something regardless so pay attention"

He huffed in annoyance at Iori's persistence. To be honest, he'd rather be spending all his time with Sogo. He had vowed to protect Sogo, who in turn promises to protect him as well. Yet it was Sogo who made him go to school everyday. In the beginning Tamaki hadn't want to go to school at all. But here he was, in school, when he didn't want to be. Of course he wanted to just use the dimensional gate to leave. But then he'd have to deal with Sogo being angry at him.

Instead of paying attention to the pointless lessons throughout the day, he just doodled on the assignments and blank paper handed to him. Sogo and Iori were both aware of his habit of not doing his school work. Neither bothered to lecture him about it. As long as he went to school.

"What are you drawing Yotsuba-san?"

"King Pudding! It's a snack from the human world, it's really good! So-chan has an entire supply for me. Since he doesn't eat sweets often, he just let's me eat it all..until I eat too much then he puts me on a diet.."

"A diet seems like a good idea for you"

"Whose side are you on Iorin?!"

The rest of their day was spent going to classes, to which only Iori paid attention to while Tamaki doodled or dozed off. He was mainly drawing the pictures for Sogo since he was always happy to receive something from Tamaki. A drawing, a small gift or something for him to experiment on. That way it wasn't just he getting something, which was the pudding and king pudding merchandise.

But right now, he also wanted to see these friends of Iori's. He didn't want anyone he considered dangerous going near Sogo. Though it was doubtful they would be as Iori would never befriend such people.
