I promised other things but here is Rinharu because Season 2
Rin's life was normal, or as normal as it could be at least. He lived near the ocean and loved to walk on its shores when there was no one around to stare at him, thinking how mad he can be to dare step on the salty waters. Ever since those merfolk had been discovered, he had felt quite in awe with them; since he loved swimming and always found the idea of living like a fish impossible. But when the first experimented in mermaid was accidentally killed, everything started going downhill in his life.
He was banned from even touching the ocean that lay in front of his house and all the swimming competitions were cancelled because they needed the pools for 'government business'; although no one told him, he was pretty sure the pools were being used to put all the captured merfolk in, locked inside the small stadiums where no one could hear their cries of anger, enchanting and mercy for help and revenge.
Rin still sat down in his terrace to look at the seas though, and felt a dumbstruck smile force into his face when he thought he saw a tail or a head poking in the distance; sure, he 'despised' merfolk as he was supposed to in other people's eyes, but he really disliked the idea of endangering such a beautiful raze of amazing creatures, just because they had tried to rebel for the murder of one of their people.
It was understandable, their anger. Rin would've gone mad if something were to happen to his sister Gou or one of his close friends like Makoto. The concept of one of the people you saw everyday being killed by some scientists trying to find out about them was disturbing and angering, it was logic the merfolk wanted revenge.
But what could he do?
Rin couldn't try to save the mermaids and merfolk dragged by the tails without mercy across the streets; the blood from their scales dying the pavements red; their pain filled cries waking him up at night. He couldn't stand before so many people against them, those who hung red flags for the people who were drowned when the merfolk wanted to get revenge. Their anger was understandable, of course, but their reaction towards the situation was just wrong.
But what could he do?
He never would've thought of helping all the other nights when he had used earphones to drown the cries of the merfolk. Never had stood in by his window and actually saw the scene. He had been described it in full detail by Makoto, who hadn't slept well since he saw it. And now he understood why.
He had been woken up like hundreds of nights before with the ear piercing wails from his street, but this time he didn't block it with music, but found the will power enough to stand up and walk to his window and stare.
It was horrible.
There. On the other side of the street a couple of feet away from the edge of his house was a scen he never thought he would gasp for. A hooded man was standing hunched, pulling a rope from behind him. He quite couldn't catch it at first, but he made out what the man was pulling with the rope and he felt his fists clench.
A mermaid was being dragged by the tail; which was a bright light blue. Blood could be seen trailing the pavement behind them. The creature was trying to grab on to something as it was being pulled harshly on the uneven pavement. Red shining blood could be seen from where the road was tied to him. Him. It was a merman. The man suddenly turned as the merman let out another scream and flipped so he was leaning on his elbows, hissing at the man. The man kicked the merman hard and raised a gun to his face, saying something and then continuing to drag him along, this time the merman didn't open his mouth to scream.
And Rin was stunned.
He had never been so angry.
In less than a minute he found himself on the pavement in front of the man, gritting his teeth in anger. "What the hell do you-" and he was already unconscious in the ground, having been met half way his insult with a fist.
Rin turned to the merman and was shocked for a second with the blue eyes that met his. Jet black hair was wet on his head and shook water as he turned his head to the side, hanging his head. Rin approached carefully and kneeled next to the merman, carefully untying the rope around the end of his tail where two thin fins started from. The creature stared at him sideways intently, watching his every move.
When he finished, Rin stood, still watching the merman. The creature stared back at him. An idea suddenly occurred to him. "You can't..." He shook his head, his blue marine eyes sparkling with pain, but clearly too proud to show it.
Rin looked around and muttered a swear. "Oh, you have to be kidding me" he kneeled again and without warning picked the merman up bridal style, and to his surprise he didn't make a sound.
He got him quickly to his house and practically threw him in his bed as he ran to fill the bathtub. This was crazy. He was crazy. But he didn't think it twice when he went out to the street.
"I'm sure I'll regret this"
