Akihiko was walking inside the headquarters, remembering Asahi and Fuyutsuki in his past.
(Flashback)
Akihiko's at the wall, peeking. He's listening to Asahi and Fuyutsuki's conversation. They're just having a lunch alone, having a quality time as a couple. Fuyutsuki said "Akihiko, come eat us". Akihiko made a confused face because he thought Asahi and Fuyutsuki didn't know he was there. Akihiko came out and joined their lunch.
Akihiko suddenly asked "What are you guys doing here alone?". Akihiko and Asahi drank tea. Asahi looked at him and Fuyutsuki replied "We're dating". Akihiko and Asahi spat out their tea and shouted "Dating!?". Fuyutsuki was shocked. She pouted as she got mad at Asahi. But she seemed blushing.
Asahi was confused. Akihiko thought to himself "Too naive eh? Pathetic, you'll get Fuyutsuki mad". Asahi pat Fuyutsuki's head, then Fuyutsuki calmed down and smiled. She behaved like a hamster.
(Back to present)
Akihiko teared a little then thought to himself "That's right. That's their last day before she left. After then, Asahi was forever serious". He cried then came someone knocking and asking him "Akihiko-San, are you there? Are you emotionally okay?". Akihiko held back his tears.
He replied "Oh, it's you Reina. Please come in". Reina entered the room and said "You don't seem okay, we're all worried about you". Akihiko replied "I'm fine, don't worry about me. It'll past, just sad that they're both gone". Reina felt sorry for Akihiko. Reina said "Come in guys, he really needs us". Daichi, Daiki, Hanabi, and Aoto entered, feeling sorry for Akihiko as well.
Akihiko asked them "Where's Yuto and the other four?". Aoto replied "Akihiko-Sama, Yuto was so depressed that he's not eating nor leaving his room. We can't find the other four". Akihiko sighed and thought to himself "Yuto...". He said to them "Please guys, give me some space for now, I lost my social battery". Hanabi said "But Akihiko-San-". Then she was cut off by Daichi and he said "As you wish, Akihiko-San". Then bowed and took their leave.
As soon as they exited the room, Daiki said "Sorry, Akihiko-San". Hanabi replied "Yes Daiki, sorry Akihiko-San". Reina suddenly heard Fuyutsuki's laugh at her back. She looked back but saw nothing. They really miss Asahi and Fuyutsuki. They all parted ways and exited the headquarters.
Shoto and Nagisa was dueling to train themselves. Nagisa noticed that Shoto was crying while fighting. He quickly shouted "Stop, wait!". They stopped dueling and rested for a bit and sat at a corner. Nagisa said "We need to have their funeral, all of them, including us were really sad about their death. We all had loss". Shoto replied simply "I guess. Just call us when you want to meet". Shoto left Nagisa alone.
Nagisa left and went for a walk. He was to make himself at ease and calm. Him while looking at the river, saw Asahi in his mind. He stopped and sighed. He remembered Asahi, his best friend. That's the place where Asahi helped him long time ago.
Out of nowhere, he sensed a knife at his back. He quickly dodged and looked for someone who threw it. Then a knife hit again, but he dodged again. Then another knife hit again, but that time, he was hit at his feet. He felt severe pain at his leg. He looked for his opponent and saw no one. Until he felt someone jumping in his back. He looked back and saw someone holding a knife to stab him. He saw the Rikuu at first glance. He looked closer and saw Ryuu trying to kill him.
