The Wandering of an Unstuck Stepbro: Multiverse Travel

(Ryoto's pov)

Okinawa resort was a fantastic place to have fun at. It was a luxurious place that no one in this class would be able to afford something like that. Maybe Lala could, but it wouldn't be fair to count her as she is a princess.

During our first day, I was on guard against... anything really. I don't remember exactly what happened, so I need to be ready. There is also the possibility that nothing will happen since Takaoka met Mil-tan up close and longer than anyone ever before. A whole 30 minutes of the experience. I would be surprised if he could live a normal life. Perhaps he lost his mind because the illusion I let him see wasn't the most family-friendly.

Throughout the whole day, nothing unusual has happened checked the food and drinks with my spider-sense, so it wasn't poisoned. I even double-checked it with my eyes so I could see anything that didn't belong there. The conclusion was that there wasn't any danger.

At the end of the day, the class tried to kill Koro-sensei using everything they've learned up until now, and they almost succeeded. Because of that, Koro-sensei was forced to use his trump card and turned into a strange round form which was clear and orange, with his face inside of it. He would stay in that form for 24 hours, and while in this form, he is invincible. I didn't join and only observed this time.

Seeing this, I was a little bit curious. Holding the ball, I used fire to see if there would be any reaction.

Nothing.

Koro-sensei: "Nurufufufu, I just said that nothing would be able to harm me at the moment."

Green stripes appeared on his face. It didn't stop me from trying a few things, though. If fire didn't work, then how about lighting?

Nope. Didn't work either, but I saw a few sweat drops on Koro-sensei's face. It seems he is aware that there is some kind of limit to his barrier, or he is not sure how much damage it can take. It's hard to tell with him.

The next thing I tried was slamming it down with all my power, but not even a crack appeared. I didn't try using my blood as I was almost sure that it would be able to go through, but his defenses were still pretty impressive.

The last thing I wanted to try was Lala's tail laser. When everyone saw that, their jaw dropped. Koro-sensei, on the hand, was still alright.

As I was having fun with Koro-sensei's helplessness and Lala was talking, we decided to go back to drink a bit and cool down, but about half of the students were tired... too tired. They looked feverish. Rio wanted to go back to her room and get changed already but lost her strength in the attempt to do so.

I checked her temperature with my hand, and she was burning. Lala, who was standing next to me, also collapsed from the high temperature. My blood started boiling seeing them like this, but I tried to stay calm and looked around for any possible clues. Food and drinks didn't have anything in them since I checked it, so it was something else entirely.

As I carefully observed my surroundings while still holding both of the girls, I noticed that Terasaka was unusually nervous.

I literally opened my eyes wide and didn't believe that he was an idiot enough to do something so stupid. No, I could believe it, but it only made me angrier not only at him but also at myself.

Ryoto: "Terasaka, what did you do?"

My voice was calm, but I was unconsciously releasing Haoshoku Haki towards him. Terasaka, of course, felt that pressure and started denying my accusations with nervous stuttering.

Ryoma: "W-what are you talking about? Why ask me!?"

Halfway through, he started being more aggressive and defensive against everyone around him.

Ryoto: "Terasaka, I always thought that you were an idiot, but in my mind, you were harmless although tactless idiot but today you proved me wrong, so if you know something, confess now, or I'll show you how hell looks like."

Besides Haki, I also let my killing intent out. The combination of these two is a deadly combo for ordinary people.

Under my pressure, Terasaka spilled everything. It could also be possible that he felt guilt seeing his classmates in their current condition.

It was Shiro that gave him a pretty hefty amount of money so he would spread odorless gas full of artificially produced virus, but according to Terasaka, the virus should only work on Koro-sensei.

As we were listening to Terasaka, Karasuma got a call from someone, and it was the big bad guy. When through the phone I recognized the voice. It belonged to Takaoka, and if Terasaka told the truth, then Shiro and Takaoka were working together, and that's not good.

Takaoka on its own is not a threat. He is just crazy, but Shiro would use his craziness to its fullest and upgrade it to boot.

I should have killed him when I got a chance, but nooo, I left him so I wouldn't change too many things, and to what did it lead to? A fucking change of a plotline! I won't repeat the same mistake this time.

While Karasuma was talking about what Takaoka wanted, I overheard that he'll be waiting at the top of the hotel.

Hearing that, I gently placed Lala and Rio on the ground while I patted both of their heads and left everyone behind without anyone noticing.

(3rd pov)

Karasuma: 'It's not good. He wants to get Yuuki, or else he won't give us the antidote, and according to him, the virus will kill everyone in three days. If it's a new type of man-made poison, waiting for help is not an option.'

Karasuma took a look around, but no matter where he looked, he couldn't see Ryoto. He noticed two of the girls that Ryoto helped when they got weaker were without him. He immediately concluded that he went to the top of the hotel where the mysterious caller would be.

Karasuma is very aware that Ryoto can be very impulsive when you push his buttons wrong, and from what he knows and observed, Lala is one of these buttons. He knew that from the way Ryoto behaved around Lala. He was a lot more stable and happy with her around, but now that she was in danger because of someone, it could mean carnage.

He needed to stop him. He could not let his student become a killer at such young age. Killing Koro-sensei and killing a human being are two different things, but with each passing day, he was starting to question it as well.

Karasuma was about to ask the students to wait for him here and take care of their classmates, but before he could say anything, the healthy kids started discussing how they would catch up to Ryoto as they also noticed his disappearing.

At first, he wanted to refuse their help as it could be very dangerous, but they were able to convince him. Koro-sensei also put in his two cents. It would be a remarkable speech about being a teacher if he wasn't being carried in a plastic bag by Karasuma.

After a few trials and confronted three professional assassins. Karasuma was unfortunately poisoned and weekend halfway through, but with the help of his students, he was able to reach the top as well.

There they witnessed...
