He kept calling him until he spotted a man at living room, who had hologram in front of him. It looked like it was a call. The man noticed him though.

"Oh, you're awake. Pardon me for the meeting, her friend was here," the man told everyone through the call.

This made Boboiboy realized something. He was in Japan! He could understans that man perfectly as he knee that he spoke in Japanese just now. He would be more glad if Nezuko was her. This is her homeland!

"Good evening kid, can you introduce yourself? I'm Aizawa Shota, the teacher of U.A. High School and Pro Hero. You have been bedridden for almost 2 days," Aizawa introduced himself.

Boboiboy startled as he introduced himself as Pro Hero. Aizawa seemed harmless to him as he had a bandage wrapped around his elbow.

"Where's Nezuko?" Boboiboy was taken back that he also could speak Japanese perfectly. This would be a great news for Nezuko.

Aizawa seemed to take back as the boy could actually speak Japanese, unlike the girl earlier, who named Nezuko spoke in different language to unconscious him that day.

"Her name is Nezuko then. She was currently in her room that I prepared for you both. Her room was next to yours. She saved you and help us heroes to defeat the villians that day," Aizawa calmly stated.

Boboiboy felt little relieved that Nezuko had done everything while he was unconscious. He must be missing a lot of things.

Maybe he could trust this Aizawa guy. He really was a hero then if Nezuko helped them to defeat the villians. Maybe he could reveal where they actually came from.

"Oh, sorry about my rudeness. I'm Boboiboy and she is Nezuko Kamado. We need a little help that might bring trouble to you hero then," Boboiboy scratched behind his head as he apologized.

"Nonsense! Young Boboiboy, come here. You came in just in time," someone called for him through the hologram call. Boboiboy nodded at Aizawa and sat next to him.

"You guys must also be the'm heroes, right?" Boboiboy took a good look at the video call.

"Yes! I'm All Might! Number One Hero!" All Might introduced himself. Everyone in the meeting room mentallt facepalmed as All Might just exposed himself to a random kid.

"Nice! I'm glad to meet you guys," Boboiboy gave a thumbs up.

"Then, Boboiboy, may you tell me about your and her information. We seem it was rather difficult to find any data about you both from all the world. I'm Nezu, Principal Nezu of U.A. High School," Nezu introduced himself.

"Eheheh, how about we just talk about this in person. Mr. Aizawa, can we..." Boboiboy trailed off as he felt awkward about this.

"Go there right now? Sure but bring along with Nezuko. She clung onto me that she refused to let me attend to this meeting," Aizawa reminded him.

"I guess we will need to take short break until they arrive," Midnight leaned backward on her chair.

"Nezuko, Nezuko. It's me, Boboiboy-" Nezuko immediately opened the door and jumped to him. He glad that he still could stand still as Nezuko was in her small size but kinda suprised that she was back wearing her Haori. Aizawa stepped back a little bit as he didn't want to get clinging again by her.

"I'm glad you're safe and sound!" Nezuko still refused to speak in her mother tongue even though she clearly could heard him speaking in Japanese just now.

"Eh, we're in your homeland, Japan! Why did you still speak in my language," Boboiboy chuckled and put her down. Nezuko just beamed her smile at him. Aizawa just got new information about her.

"Yes, even though I already know we're in Japan but everything around us is in modern, just like in your contry," Nezuko finally decided to use her mother's tongue.

"Huh, you lived in a village then? That's explained why you not used to everything, especially technology," Aizawa jumped into their conversation. Nezuko just nodded at him.

"Nezuko, come with us. The heroes are gonna help us, just like how we are gonna help you that day," Boboiboy held out his hand for her. She happily took his hand. Aizawa just led them to where the meeting was holding.

"Good evening, I'm finally attending this meeting in person. Sorry for taking a long time," Aizawa came in with Boboiboy and Nezuko behind him.

"Please allow me to introduce ourselves. I'm Boboiboy and this is my sis- friend, Nezuko Kamado," Boboiboy introduced themselves to the teachers. They nodded at them and decided to introduce themselves too.

"So, Young Boboiboy and Young Nezuko, what can we help for you?" All Might asked them.

Boboiboy took deep inhaled and started explaining about them, "Actually, we are not from this world, even Nezuko is not from my world. It was started with Nezuko, who got sent to my world as the culprit's goal was to make Nezuko become 'evil' again.

We managed to help her in my world. It didn't last long as it was only took an hour for her to get send to another world, which is here. I might accidentally got sent together with Nezuko because I was defending her from getting hurt. So, please help us!" Boboiboy bowed to them. Nezuko didn't know that she also followed his action.

"That was too cruel! Poor children that got seperated from their family. How can someone want her to be evil!" Midnight leaned forwards.

"But I don't think your world has a quirk like us. That culprit probably wants her to be evil again because she has natural abilities with her. Besides, there is no data says about her power," Tsukauchi stated. Both Boboiboy and Nezuko just tilted their head in blank.

"I'm sorry but what is quirk?" Boboiboy raised his hand slowly. Nezuko nodded besides him.

"Aizawa totally needs to be in good care for the kids," Vlad King mumbled.
