Sin 15: A favor

"Isseeei!" Haru's scream was quickly audible when Haru's original body landed less than a meter from where Issei was resting.

Issei had his eyes closed and was breathing slowly, just to one side of the chestnut body standing was a woman with crimson hair and emerald eyes, the uniform she wore was the officer of the Kuoh academy.

"Rias Gremory" Haru muttered with a stern expression, he did not let his guard down at any time and had his Byakugan active scanning all his surroundings in real time 'My chakra reserves are below 30% I can still deal with more enemies, but I will have to use that technique ... '

Rias was standing in the same place with her arms crossed at chest level while keeping a smile on her face "You don't need to be tense Haru Yoichi, I have no intention of hurting your brother" Rías spoke in a tone of voice natural but Haru could see how her body trembled slightly.

"Who are you? ..... No, that question is wrong, the real question is what are you?" Haru asked as his hands formed the seal of the Ox.

There were no people in the surroundings who could see what was happening, everything was covered by dozens of crows that observed all the space.

The tension between Rias and Haru was reaching its climax but she didn't lose the smile on her face "Kuck!" Issei complained due to the pain of his injury.

Haru was quickly altered approaching the chestnut's position with concern "Hold on a little more Issei, I'll take you to a hospital" Haru said taking Issei in his arms 'I should have trained medical ninjutsu' Haru complained in his mind remembering the specialty of Tsunade the fifth Hokage from Konoha in the original naruto series.

"Stop!" Rias exclaimed, stopping Haru who was about to retire

"You have no intention of letting me go?" Haru asked, showing annoyance in his words while looking at Rias on the other side "As you can see I have my brother in a terrible state but if you want to fight I can do it at any time"

"That is not my intention, I can help you deal with Issei at school" Rias said going straight to the point

"What do you gain by helping us?" Haru asked without letting his guard down

"For now consider it as a small favor coming from a senpai, also if you come to a hospital with those wounds and all the blood in your body you will have more problems, don't you think?" Rias asked turning around to guide Haru and Issei.

Without saying anything else Haru followed the redhead to school in less than ten minutes, Haru charged Issei to the abandoned building at the back of the campus.

"Welcome to the occult investigation club" Rias said as he opened the doors of the old building that maintains an aura full of nobility.

"Okay, now is not the time for introductions. Issei needs treatment" Haru said urging Rias to stop talking.

Both continued down the hall to enter a room where there were several sofas and a desk, inside the room was another person waiting, the dark-haired beauty that Haru had been watching with the help of the crows, Akeno Himejima.

"Akeno take care of Issei Hyodo's wounds," Rias said immediately upon entering.

"Sure president" Akeno said approaching to where Haru was to take Issei from the latter's hands.

"Take good care of Issei" Haru asked with a worried tone, handing his brother over to a group of people he had barely met didn't feel well, but Rías was right in case they both appeared in the hospital they would only have caused more confusion and the parents of both would have been involved in the matter.

While Issei was being treated by Akeno, Haru was standing leaning against a wall with his eyes open and the byakugan active, he was monitoring in real time everything Akeno did when treating his brother.

In the main chair behind the desk was Rias who was silently looking at Haru and remembering the scene she witnessed earlier.

Soon the time passed and Akeno had finished healing Issei, there was no word between Rias and Haru until that moment "Everything is ready president, now you just need to rest" Akeno said leaving the room where she was healing Issei with a smile in his face.

Haru didn't say anything, he just went to his brother and took him in his arms "I appreciate your help in this, having said the above I owe you a favor Rias Gremory" said Haru lowering his head in gratitude

"You don't need to pay me for this, I just ask you to come to the club tomorrow and listen to what I have to tell you" Rias said with a smile on his face as he looked Haru directly in the eye.

Before turning around, Haru gave his brother a look. "You really end up getting me into something troublesome," Haru muttered ruefully. "Well, tomorrow after school I will come all the way here to listen to you."

"I'll be waiting for you" Rias said looking at both brothers one last time before Haru opened the door to leave the hidden investigation club.

Outside the Haru club I create a couple of clones, one of them took on the appearance of Issei and both clones entered through the front door to take the siblings' place.

Haru entered through the window and left Issei in his own bed before returning to his room by himself.

"I was very naive to think that I had only reincarnated into an alternate version of my world with a system that would help me have fun" said Haru sitting in a desk chair while spinning a moment "Fallen angels ..... Apparently Rias Gremory and his company would be other races by conjecture it would be about demons, of course if there are demons and fallen angels, there are also pure angels "

"Sigh ...." Haru let out a long breath "what did I just get into?"
