Football frontier international had concluded four months back. A new school year has started in Inazuma town. Previous second years are in their final year of middle school while their juniors are now in the second year. Toramaru has now joined Raimon as the first-year student. He had been immediately recruited in the club when he had told the soccer club that he had joined their school.
Everything was going well until Kidou's household received a phone call that was going to change everything for Kidou Yuuto and Otonashi Haruna.
Kidou was hanging out with Genda and Sakuma when Hakamada had interrupted them. "Kidou-san there is a phone call for you" Hakamada informed his young master.
"Arigatou" Kidou thanked the older man.
"Hai, this is Kidou Yuuto speaking" he answered the call.
"Konnichiwa, this is Michinari Hachiro. I am a lawyer based in Inakunijima." he heard a man introduced himself.
"How may I help you?" Kidou was confused as to why a lawyer from a small island would be trying to contact him.
"I am contacting you in regards to your maternal grandmother" the lawyer informed him.
"What about my grandmother?" Kidou asked with a frown as he tried to figure out what was going on.
"Your grandmother wants to meet you and your sister" came the reply.
Kidou wasn't expecting that. "I am afraid you must be mistaken. You must be trying to contact someone else" Kidou explained.
"You are Kidou Yuuto from Inazuma Japan?" the lawyer questioned.
"Yes I am" he responded.
"Then, I am not mistaken at all. Your grandmother is very sick and, she would like to meet you and your sister before anything happens to her " the man revealed to Kidou who could feel his heart thumping inside his chest.
"My Oba-san is dead. We have no family left. Sensei, we if we had a living family member we would have known. My sister and I would have been living with them instead of getting adopted by different families" he replied in a slightly high pitch voice. He was starting getting angry to get angry now. "How can a grown-up man joke about it with him?" he thought.
"That is not true. While I don't know why you kids didn't grow up with your grandmother, I can, however, confirm that you indeed have living family members" The man sympathized with him.
"Living Family members? Who else is there?" Kidou was hesitant to ask that.
There was a pause before he heard the answer "You also have a brother".
"A brother? you must be mistaken. I only have one blood sibling and, that is Otonashi Haruna, my sister. " Kidou choked out the words. He was having difficulty speaking by now.
Sakuma and Genda who were silent, during the whole conversation exchanged alarmed looks. They were both trying to figure out what was going on. They both, however, knew that this was not good. Sakuma approached Kidou and laid his hand on his shoulder as silent support while Genda went to fetch water for him.
" I am sorry that you had to find out this way but, you do have a younger brother. He is a year younger than you and, his name is Kirina, Hiura Kirina" came the apologetic reply.
Kidou felt himself going into shock. "He had dealt with fake aliens, Angels and demons in the past and yet he was finding living family members shocking. What was wrong with him?" he wondered. "This is not a prank, is it?" he stammered out. "Get a grip, Yuuto" he scolded himself mentally.
"I am sorry, but it is not a joke. Your grandmother wants to see you both as soon as you can arrange it. She is looking forward to your visit. I will be in touch. Goodbye," the man concluded the call lightly.
"Arigatou gozaimasu" he thanked him.
He felt someone nudge his shoulder gently. He looked up to see Genda looking at him with a frown. He took the glass he was offering and took a deep breath. It was then he realized that he was crying. When did he start crying? "are you alright?" he heard Sakuma asked. He remains silent. He knows, he does not need to say anything both of them knew him well enough. He doesn't need to tell them how he was feeling right now.
Kidou then immediately called Haruna to ask her to come to his home at once. If what the lawyer was saying is true, then Haruna needs to know too. This time he won't hide things that affect both their lives from her.
It was 20 minutes later when Haruna arrived, worry visible on her face. "Onii-chan, what's wrong?" Haruna asked her brother, urgently.
She tried to guess what was going on. There were Sakuma-san and Genda-san present with her brother. Both of them looked concern. Her brother, on the other hand, looked like he had seen a ghost.
She was worried and, Kidou could very well see that. He hated doing that to her, but this was important. He gently guided her to the sofa and made her sit down. He then sat next to her grabbing her hand tightly into his.
"Haruna, I receive a call today from a lawyer. He said that our maternal oba-san is very sick and wants to meet us for one last time. He also said that we also have a brother" Kidou tenderly told Haruna afraid of her reaction. He saw her eyes go wide as she took in his words.
"How is that possible Onii-chan" she was able to ask.
"I do not understand it myself" he replied.
"Why cannot I remember him?" she questioned him. "We should have remembered him. All my memories are about you and me. Otoo-san and Okaa-san were in some of them. There was never another boy. "Why do you think our grandmother never took us in?" she continued to fire questions at him.
" I have no answers to your questions Haruna. Even I am confused, and the only person who can answer them is our grandmother" he consoled her.
"What's his name?" she asked him quietly.
"Kirina. Hiura Kirina." she nodded in response.
"We could have grown up together" she whispered silently crying. Kidou pulled his sister into his arms to comfort her. "I know, I know".
After a while, they were sitting silently with Sakum and Genda trying to figure out what to do. Both of them had stayed behind to take care of them. They knew that the siblings were too shaken up with the revelations to be left alone. They had even coaxed them to eat a little.
Kidou had made up his mind that he would go visit Inakunijima to find out more about the whole deal. "I have decided that I would visit the island this weekend to meet her" he informed them.
"I am coming with you. We need to do this together." Haruna interrupted.
Kidou didn't object he knew it would be better for them to face everything together. It would be better to meet their brother together.
"I just thought of something" Haruna interrupted his thoughts.
"If Kirina is a year younger than you does that mean he is my twin brother?" she probed.
"That is a possibility, yes, or he was adopted. There is no way okaa-san could have three kids in two years without having twins" he answered.
"A twin huh" Haruna began to wonder about it.
"I think that we can leave on Friday after school and return on Sunday. We should also book a room in a hotel. " Kidou started making plans.
"We will come with you" Sakuma cut in.
He looked up to see Genda nodded in agreement to Sakuma's words.
"You guys don't have to come with us. You guys have football practices to run" he objected.
"Do not be silly, Kidou. This is a huge thing for you guys. Both of you will need our support there. Finding out that you have other living family members other than each other isn't easy. You should not be alone" Genda argued.
"We are coming with you no matter what" Sakuma declared in the end.
Kidou was getting overwhelmed with the support his best friends were showing him and his sister. He could see Haruna agreed with his best friends, so he gave in. "Why was he surprised?" he wondered. He had taken up the vacation before school started to rebuild his friendship with both of them. He was also repairing his relationship with his sister at the same time. Because of that, Haruna had been spending a lot of time at his house. She had gotten close to Sakuma and Genda in the process. He knew both of them saw her as a sister they never had. The four of them had built a small family consisting of themselves over the summer.
They spend a lot of time discussing what they can do and how to proceed about it. They had planned a weekend worth of the trip with room to extend the trip if required.
In the end, Kidou and Haruna were still not prepared to find out more about their grandmother or their brother.
