So yeah, they had enough experience in manhwas, manhuas, mangas or whatever to know that their next step should be carefully decided. 

The room had two doors. They decided that one of them would check the first door and the other the second. In complete silence they went to the opposite directions and got close to their doors. They slowly reached for doorknob and turned it to open the door. Mike looked inside first, made a grimace and went to join Kiki.

'Bathroom' he said, which made the girl smirk. Then they silently opened the door, just enough to let the head pass, and looked around. It was a hallway, there was a door on their right, two in the front, and most importantly a delicious odor of pancakes being cooked.

It took all of their self control not to let their stomach grumble, since they really didn't want to humiliate themselves, and it really felt like the typical scene off a character A being hungry and not admitting it and being shamefully discovered by character B.

By instinct they searched for character B, and finally discerned Aizawa looking at them from the end of the hallway. They had a moment of surprise, then bliss, and finally panic, for they were pretty sure they looked like weirdos right now.

Mike who was above decided to open the door wide to make it look like they were totally coming out, not at all inspecting the grounds. But it made his friend fall forward, as she was leaning towards the front and slightly supporting herself from the wood. 

It sounded 'bam' 'bam' 'boum', although for Michael it sounded more like a death threat. 

He froze for a second but then tried to help her stand up before realizing she didn't need help as she was already standing. He shuddered but she patted him on the shoulder to tell him he was forgiven.

So anyway, Eraser Head greeted them, and they greeted him back, with a big smile and tears flowing out of their eyes though the later was unwanted it was just the emotion. The Pro-Hero mentioned there was pancakes for breakfast, so they followed him to the living room, while trying to memorize the most details they could about the Pro-Hero's house.

Trying at the same time not to look too creepy.

While eating they were informed that they would continue with the interrogation, and also determine where they would stay while figuring out how they could come back to 'their world'.

The last part socked the kids a bit. They had never really thought about it. They didn't have time. They were too amazed by their surroundings. So as they finished their meal, their attention went to the spell they used.

They used a satanic ritual or more precisely an weird anime ritual to arrive, wouldn't it be logical to destroy it to come back?

But if it was annulled, would they be able to come back again?, they wondered when washing themselves one after the other in the shower and washing their teeth.

It had to be tested.

There where two people.

One of them could be sacrificed.

And, they both knew, that when the adults would realize that fact, it would be the moment of the battle.

The final battle.

Also called, the 'No-no-I-insist-let-my-friend-try-if-by-destroying-her-ritual-sheet-it-is-possible-to-come-back' battle.
