Goku was riding his nimbus back to the city as he dropped off and landed on Dagobah Beach. He saw the sun rise, feeling the breeze as he made sure he had a backpack filled with the stuff that he needed. However a sound took over making it sound like a monster as he started to laugh. 

Goku - I should get something to eat. Maybe I can get some food before school. Yeah I'll do that. Izuku said the city in the center was the best so I should head there.

Goku decided to fly to the center of the city as he walked around the area. 

Goku - Man I don't know what to choose for breakfast maybe some beef Katsudon or chicken flavored Ramen? 

"Bump"

Goku turned to his left side as he saw a small little girl in a dirty white gown with her arms and legs bandaged. She had silver hair with a horn on the right corner of her forehead.

Goku - Oh I'm sorry. You took a tumble.

He reached for her but she was shook when he did as he pulled back but picked her up still feeling her whole body trembling. 

Goku - It's okay I won't hurt you. My names Goku and yours?

??? - It's not nice to disturb other people Eri.

Goku looked up and saw a man dressed in green and black as he had a dress shirt covered by a fur jacket but what stood out more is that he had a type of bird face mask.

Goku - Oh you must be her father?

Chisaki - Yes. Eri you shouldn't run off like that. Now we should hurry home.

Goku suddenly felt Eri hold him much more tighter as she said a few words and this changed his perspective of the man in front of him.

Eri - Please...please don't go.

Goku then moved his hand to caress her head to calm her down as he still didn't wanted to act until he was truly understandable of the situation.

Goku - Eri seems to be scared. Do you know any reason why?

Chisaki - It's normal for children to be scared after a scolding. Maybe we can talk in a place a little more private. It's embarrassing to be discussing in place like this.

Goku slowly picked up Eri as he decided to talk to her mentally.

Goku - Eri don't be scared. I'm talking to you in your head, now listen to me. Count to ten and then run back to me but make sure to have your eyes completely shut. Okay.

Eri looked at Goku as he kept his eyes on Chisaki with both walking in an alleyway. She slowly nodded as she looked back at Chisaki and saw that he was reaching for his glove.

Chisaki - Eri is disobedient no matter what I try but she just keeps causing trouble.

Eri quickly got off Goku's arms as she walked back to Chisaki as he turned around and with every step Eri counted.

Goku quickly called for Chisaki as Eri got to ten as she ran back to Goku with her eyes closed as Goku put both his hands on his face while closing his eyes as well. 

Goku - Solar Flare!

The flash of light blinded Chisaki as he tried to fix his eyes but nothing the pain was still there as he held his eyes in pain with Goku picking up Eri as he quickly flew away and went straight to U.A as he decided to use his Instant Transmission to appear next to Izuku. 

Goku landed on the ground with Eri still in his arms. 

Izuku - Goku? What's going on? 

Goku - Hey Izuku. Thank goodness we made it but just give me a second.

Goku walked towards Principal Nezu as he told the story about what happened between the encounter with Chisaki and Nezu was proud of Goku with his brave action and made sure the police were informed of Chisaki. Goku hoped for Eri's sake that they never encounter him again.

Goku then went to his class with Eri in his arms covering herself still scared and not comfortable in being in a public space. 

Goku - It's okay Eri. Nobody will hurt you again, I can promise you that.

Eri looked at his eyes and saw the honesty and kindness in his eyes as she again covered herself in his arms. Goku made it to his class as he knocked and was called in. 

Aizawa - Now everyone be good to our new student. Come in.

Goku walked in as he gave a small wave and he introduced himself. 

Goku - Hi everyone my name is Son Goku but please just call me Goku and this one here is Eri. She's new to public spaces so please be easy on her. 

Everyone - Hello.

Aizawa - Goku you can sit behind Todoroki. Todoroki raise your hand please. 

Todoroki raised his hand as Goku walked to the desk behind him it was a little cramped but Goku decided to just let Eri sit while he created another chair made out of his energy as he sat down and he looked at the board with the classes going on as per normal. Thanks to Mr. Popo teachings Goku was able to understand everything the teachers were teaching as Eri laid on Goku's lap. 

Goku was surprised for a second but smiled as he rubbed her head as he picked her up and held her like if she was a baby as he then received a blanket and a pillow from Momo Yaoyorozu. 

Yaoyorozu - It would be better if she laid down with this.

Goku - Thank you.

Goku laid Eri down on the chair as he placed his backpack as a pillow and laid the pillow for Eri to lay her back on also covering her with the blanket.

After a few more hours of class everyone was ready to leave for lunch as Eri woke up since everyone was talking and she noticed Goku getting up as he did a few stretches.

Eri walked up to him holding his leg tightly as he turned around and smiled. He picked her up and went with Izuku, Iida and Uraraka to lunch as he ordered a bunch of food for himself and Eri. 

Eri - thank...you.

Goku - Eri there's no need to thank me. I'm happy your safe and well. How about this. I promise you that I will always be here no matter what. I will never leave you alone. 

Eri hugged Goku as this got everyone's attention but he didn't care as he hugged her back and he let out a small tear when he heard Eri's next words.

Eri - Thank you Papa.
