Myth (my hero academia x oc)

Uncharted territory

It had been three days since the heroes found the merman. The heroes had quickly built a special facility for the boy, the building was a bit far from campus. It was also with in walking distance, the building was warm on the inside but had a special pool that was at freezing temperatures. The pool was very deep and it had an ocean like floor with sand and rocks at the bottom. Arran laid at the bottom of the deep end, the heroes were carful not to disturb him while he recovered from the drug. As Arran opened his eyes slightly as he began to wake up, as the merman glanced around he noticed he was in a different place. A string of panic rose in him, The merman sat straight up as he looked around the place.

 Only to have his head throb harshly, Arran put a hand on his forehead then removed it. Arran cautiously began to explore his new surroundings. Nothings seemed too dangerous so far, it actually reminded the merman of home. Arran started to swim to the surface slowly. This place smelled strange, it didn't smell like the ocean. Arran poked his out of the water slightly, only having his eyes above the water.  To his surprise there was a land creature, it was unnerving.  The land thing seemed to notice the merman and looked at it with slightly shocked face. Arran sunk a little more into the water as the creature looked at him. 

"Ah your awake and alert, good. I don't know what exactly you eat but the school caught some fish for you." Aizawa said as he threw the fish in the water. Arran swam to the fish while keeping a close eye on the land thing,  the fish did smell good however it wasn't an artic fish which made the merman look at it with a disgusted look. Aizawa gave sigh as he crossed his arms, was this creature really being picky over fish? 

"Look that is all we have right now, take it or leave it. I'll back later to check on you, try not to do anything stupid while I'm gone." Aizawa said with a sigh. With that Aizawa left quietly leaving the merman in the strange place alone. Arran quickly ate the fish that was given to him, soon after the young merman began to swim around the large tank exploring every crack and crevasse.  As Arran looked around the bottom of the tank, a loud thud sounded through out the building. Arran cautiously swam to the surface, only to find the grumpy tired man with three other land people. One had spiky hair, the second had seaweed colored hair, and the third had two different colors of hair. Were all land people this weird? The multicolored haired boy looked at Arran with a surprised face. Arran quickly swam to the bottom of the tank and went straight to the deep end. He laid down behind a large bolder feeling fear fill up in him. 

"Why are we here?" Bakugo growled as he looked at the water with a scowl.

"You are here because the school wants you three to help the creature we rescued. You need to gain his trust and help him out. Do not get in the water unless he's not afraid or you keep far distance from him."  Aizawa explained. 

"Who is him?" Deku asked with curiosity. 

"Him as in the merman we saved, we don't know his name yet. So we don't know what to call him. That's another reason why you are here from now on you three will spend your third period here, you will come here everyday. Occasionally a hero or teacher will come here and check up on your progress. We think this is something you three can do on your own. This is not negotiable. " Aizawa further explained. Todoroki gave nod in response as he looked at the water again.  Bakugo gave out an annoyed groan while Deku looked excited. 

"Interesting, I hope he will like us." Deku mumbled to himself. Bakugo rolled his eyes as he glanced at the water.

"Uh huh. Well, get to it and make sure you go to your next class after the bell. Also there are some additional instructions on the tableover there." Aizawa replied as he left the building.  The three stood there in silence for a while with nothing but the sound of water echoing through out the building. Deku walked up to the pool and stood at the edge of the pool, while Bakugo grumbily looked through the instructions given to them. Todoroki joined Deku by the pool and watched the ripples of water splash against the cold stone wall of the pool. 

"Wonder if he knows if we are here. What do you think Todoroki?" 

"I think he does, I thought I saw a glimsp of him earlier. I could be wrong though." Todoroki replied as he crossed his arms. Bakugo gave a growl as he started to complain.

"Eh? I say this is a load of bull why are we taking care of a fish thi-" 

The angry pomeranian was cut off by a big wave of water splashing against him causing him to get soaked to the brim. Bakugo slowly looked at the water with a look that could kill, to his suprise he saw Arran looking at him angrily. Calling him a fish was just rude and an insult, who was he to call him that. Bakugo motioned to walk to the water but stoped in his tracks when Arran hissed at him.  

"Ha?! You little-" Bakugo began to shout when Arran slashed another wave of water at the blond boy. Arran gave another hiss as he dove back under the water, this might be harder then they thought.
