Hikari doesn't know what they're celebrating there. But since it looks like they were having fun, He just gets along. Hikari was thinking that maybe he should just forget about anything and just release all of it.
Maybe it was Akaru plan who told everyone to do it. But when they were happy, Hikari just reminded Aimi. He talks to himself "I wonder what she was doing now. But there was nothing to be worried about. She can do it. Everything by herself." But when Hikari was thinking about it, Yami says to him "Hehe, Seems like you were worrying about your.... girlfriend?" Hikari closes his eyes and takes a deep breath. He didn't say anything to Yami and just ignore it.
Then Hikari says to them "Well, How if we end this now. It seems like there was nothing more for us to do well." Yami just can't believe that Hikari would do that. He didn't want to disturb Hikari or he maybe will be used to clean all of that mess. But when he was looking at Hikari, suddenly his vision got covered by a shadow. he was thinking that maybe it was okay for him but it seems like the effect will go to Hikari. The shadow spread out quickest than he thought. He quickly searches around for a reason for it.
When Hikari was helping them, suddenly he got a headache. He was so weird with it. He tries to ask Yami about it but his words can't reach Yami. Maybe Yami was having a problem in Quantum memory too. Hikari didn't have any time to deal up with it. So, he just leaves it to Yami. Since Yami is him, he bet that Yami can get through it.
When Yami was searching for the reason why did that happen, he found someone inside of quantum memory. He goes to that person and asks him "Who the hell are you? I will kill you if you make any mess here." that person didn't look at Yami. he didn't make any reaction to it. but he asks Yami "What makes you so sure about it?" Yami was just disappointed when he heard that. He doesn't know what should he say or do after that. When saw Yami reacts to it, that person suddenly disappears and everything returns to normal. Yami was so weird about it. he says by himself "Just what in the world is he?" Yami didn't know if Hikari hears what did that person says. but he was thinking that maybe he shouldn't tell Hikari about it because it will make worries.
After Hikari did helping the others with it, Hikari says to all of them "Thank you!" but they say to Hikari that he didn't need to say something like that to them because they just do it because they would like to do it. there was no other reason for it. After all of them go away, Suddenly Ageru arrives there. Ageru looked at Hikari and says "So, it was all over?" Akaru and Hikari just looked at Ageru at that time. Ageru was feeling weird at that time. She quickly asks them "What do you want?!" then Hikari answers it "So, you're planning to not helping us even a little? Just what the hell with it!" Akaru told Hikari to keep calm. He says to Hikari "I guess that it's maybe a time to let her pay for it." Hikari agreed with it. Ageru was so weird about it. She quickly asks them "Wh-What do you want?!" Suddenly someone appeared there and asks them "So which of you are going to become my part-time worker?" Then both Hikari and Akaru tell that person that it was Ageru.
that person goes to Ageru and says "Hey, What are you thinking are you doing. if you're my part-time worker so help me with those dishes." Ageru was so shocked when she hears that. She never meets with that woman before. She asks that woman "Since when did I say that I will help you?" That woman just can't believe it. She grabs Ageru along with her and says "You accept this work so you just do it. Just why with you?!" After Ageru and that woman leave the place, Akaru says to Hikari that they need leave the place. But before they go, Hikari told Akaru to give him some time. Akaru accepts it and told Hikari that he hopes it won't be a long time.
Hikari looked at the stage, that place was a thing that he will never forget. It was a moment of his life started. Hikari smiled and says "I never thought I will return here and do the same thing that I have done before. When thinking that I need to face everything again. I never thought this kind of thing will happen. But for real, Even all of you will remember me or not. I'm so glad to see all of you happy." Akaru pushed Hikari a little bit and says "Just forget about it, At least they all remain in your memory. It was good enough for me." Hikari just thinking that maybe there was a truth behind those words. But it was kind of selfish for him. Because he never thought about making himself happy instead of the others even the others want to see he smiled but he just can't do it. It was not fair for him and his promises. Akaru told him to not so serious about it. Akaru says to Hikari "I and Ageru know you well. Even one day, You need to fight again. Both of us- No, All of us will help you." But Hikari didn't very happy when hearing that. It looks like he just giving them a burden more. Because when he reminded to when did he going to fight with Yami, all of them just the ones who carried him. even he was facing serious quantum brain damage at that time and causes him faint many times. He will never get through all of that without them. But Akaru declined it. He says to Hikari.
"You should be glad because you are yourself. Your self is the one who helps you at that time. I don't think everyone will survive something like that. You're the only one who can do that you know?"
When talking about that, Hikari started thinking about someone. But he didn't think that he has to worried about it because he knows that the person he was thinking about will be okay now. Then they leave the place and return to a place they live.
When Hikari was walking away, he found something on the floor. It was a letter. Hikari didn't think that he should look at it, But he saw his name on that letter. the sender is unknown but maybe it was someone from the party before. Hikari takes it then he opens it. He was weird when he read that.
"Don't you think it was too early for a celebration? Your story is still far away. You didn't even know if you can face it or not. But you should know that there were a lot of people that know you can do it and succeed. Here I'm hoping that you will succeed. Don't care about who is writing this. But It isn't a message to tell you that the war will start."
Hikari was weird about it, but since the writer of that letter says that. He didn't think that he should find out who is it or try to investigate it. When Hikari was walking, suddenly someone called him.
"Hey!! Are you from the party earlier?"
Hikari turned back and look at it. But when looking at that person, he just a bit shocked. he didn't ask anything from that person then let that person talk about what he wants.
"Well, I was watching it from afar. It seems like you're a really special person. What's your name?"
"Aikari. Just call me Aikari."
That person asks Hikari another question. But Hikari says to him that he needs to return to his place quickly. That person didn't let Hikari go as long as he didn't tell him the answer. That person asks Hikari that question again.
"Who you really are?"
Hikari doesn't know why, but he got a feeling that he does not need to answer that question. That question really makes him suspected something from that person. Yami says to him "What if we just go away and leave him here?" Hikari was thinking about it too. But in that way, maybe that person will know where did he live. So Hikari says to that person "Sorry, but I need to buy something from the store." But that doesn't work for that person. That person says to Hikari that he does not care to walk together and talk about it. Hikari rejected it and says "Sorry but I don't like to grab the others into my problem."
"Well, then Maybe I meet with you at the wrong time. See ya later."
Hikari didn't plan to go to a store, but he just goes there and buy some snacks. He looked around him to make sure that no one was following him. When he confirmed that no one was there, he walked outside normally and talk by himself "Why did this kind of thing happen? Did I really going to become a cause of the war again or I'm going to bring up peace?" Yami disagrees with what did Hikari just said. Yami says to Hikari "It's better if you just go to where did you want to go now. Stop thinking about that and just keep moving forward." Hikari agreed with it and just return to his room.
Since Hikari got a bad feeling about what did just happened back then, he spends his time inside the quantum memory.
Hikari asks Yami "Who do you think that person is?" Yami didn't have any idea about it. Yami has checked it inside the quantum memory before. But it seems like Hikari hasn't met that person before. Suddenly a weird question appeared in Yami's mind.
"Wait, Hikari. You say that you never remember who you are after that incident right?"
Hikari nods his head and asks Yami "Why? isn't you have my old memory?" Maybe that was true but Yami just can't sure about it. He says to Hikari "I don't know if I am true or not. But, Since they attacking Quantum memory before even they failed because I lose. Is it logical for them to manipulate your memory back then?" Hikari didn't think that was what did happen. Because if they want access to quantum memory, they must enter it like how did He and Yami do. But no one can enter it because of the quantum brain effect that has killed a lot of people. Yami just thinking that was a bit true behind it. But they didn't know if quantum memory is more than what did they thought.
Maybe they will found it out later, but they can't confirm when that will happen. When looking at what did Hikari have face before, Hikari just needs to face it one by one. A problem came to him one by one. but, it just once in Hikari life that he needs to face one problem while he was going to finish one problem.
Not long after that, Yami has some requests for Hikari. He asks Hikari about it. But Hikari just hard to accept. He asks Yami "Can I believe in you take this turn? You ruined my life many times. Even you helped me sometimes, I just can't believe in those words." Yami tries to entrust Hikari about it. So since Yami was saying that, Hikari just gives Yami permission for it. But Hikari says to him "I don't know what are you planning to do. But, just make sure that you beware of everything." Yami agreed with it. He just didn't believe that Hikari would say that. Maybe it is just because Hikari started to change himself after he meets with Aimi and Ayasa. Yami doesn't know why but Hikari was different from before.
On the next day, Yami woke up and Hikari told him to go to where did Neu and Nimura are.
