"I was joking," Yuuki said while trying to push this big guy in front of him.


    Gouzaburou nodded in response.


    "So your wife and daughter are also here?" Yuuki asked.


    "Yes, we have decided toe to this ce for a while," Gouzaburou nodded.


    "Is there a problem in your ce?" Yuuki asked.


    "Nothing. It''s just Sun-chan wanted to change her school here." Gourzaburou clenched his hands and said, "But those guys are too annoying! I will never let them bother my Sun-Chan!!!!!!"


    ''Doting parent....'' Yuuki and Hiratsuka thought that at the same time.


    "Dear!"


    Then suddenly someone hit Gouzabourou''s head and he fainted on the ground.


    "...." Yuuki and Hiratsuka looked at the woman who had knocked Gouzaburou.


    "Aunt," Yuuki said.


    "It''s mom, right? Also, it''s better if you call me big sister," Ren said with a cold smile.


    ''Big sister?'' Hiratsuka, who was by their side, couldn''t help but felt weird. She looked at Yuuki and asked, "Mom?"


    I have thought of him as my child, right?" Ren said.


    "Yes." Yuuki nodded since he had proimed to be Sun''s older brother.


    "If you have time then you should visit our new house," Ren said.


    "I''ll do that." Yuuki nodded and agreed to visit her when he had time.


    They talked for a while and knew that Sun was in the 1st year of high school since she was younger than him.


    Yuuki said to them that he decided to go back to his ss since he was quite hungry. He didn''t think that when he was away for two days Sun had transferred into his school. He entered his ss before he heard someone.


    "That''s Yuuki."


    Yuuki heard Kuina''s voice and turned.


    "Yuuki!"


    Yuuki was suddenly greeted by someone and hugged. He was wearing his sses and felt a bit surprised for her to realize that it was him. "Sun-chan?"


    "Yes!" Sun was happy when she saw him. She had beening to this school and wanted to surprise him only to know that he hadn''te to the school for a while. She talked to her ssmates and knew that he hade to school today.


    "It''s good that you''re here," Yuuki said while patting his head. He knew that it was somewhat dangerous when the Khaos Brigade was terrorizing the world and he thought that there should be someone from mermaid too who had joined that organization.


    "Hmm." Sun seemed happy when she saw him happy to see her.


    "Yuuki, do you know Sun-chan?" Hinako asked.


    "I have met her before during Summer Music. Both Uomi and Yukari have also met her before," Yuuki said.


    "Summer Music!" They knew about that event and didn''t expect them to know each other during that time.


    "So what''s your rtionship?" Chiaki asked since she knew that it was the most important question. She was wondering whether this girl was also his girlfriends.


    "She is my little sister," Yuuki answered.


    "...."


    "What?!" They were startled when they heard it.


    Ranko wasn''t that surprised and she also wasn''t here since she was ying in Yukana''s ss.


    Only Izusu along with the girls in Hitotose dorm was surprised when they heard it.


    "Little sister?"


    Sun who heard it, couldn''t help but feel down, but she changed her expression immediately.


    Chiaki saw the change in Sun''s expression and nodded profoundly.


    Yuuki sat down in his seat while talking with them. He noticed that Hinako''s expression was a bit strange. "Hina-chan, what''s wrong?"


    "Eh?" Hinako seemed surprised.


    "You seem to have something on your mind," Yuuki said.


    "Well...." Hinako was wondering whether she should tell them.


    "What''s wrong, Hina-chan?" Mayuki asked.


    "Yes! Please tell us anything!" Kuina nodded.


    "You don''t need to be reserved for us," Chiaki said.


    Hinako looked at them and nodded. She took a deep breath and decided to tell them. "My mother wille to Hitotose dorm."


    "..."


    "What?!" Chiaki, Kuina, and Mayuki were startled.


    Sun was a bit confused and asked Yuuki, "Is it something to be surprised about?" She thought that there was nothing wrong when Hinako''s mother came to visit her daughter.


    "Hmm, it isn''t something strange, but Hina-chan is from somewhere quite far away," Yuuki said.


    "Oh? Where?" Sun asked.


    Yuuki had forgotten where Hinako''s home was but he knew that it was in the countryside. "I am not sure, but it is quite far away."


    "Hmm...." Isuzu nodded.


    Yuuki, Sun, and Isuzu looked at Mayuki, Kuina, and Chiaki who seemed panicked.


    "I need to buy new books when your mom ising!" Kuina said.


    "I need to make the kitchen and cafe to be more beautiful!" Mayuki said.


    "Then, I''ll call the designerpany now!" Chikai said.


    "Awawaawawawaw!!!!" Hinako didn''t expect their reaction to be quite exaggerated.


    "Wai!" Yuuki stopped them.


    "...." Kuina, Mayuki, and Chiaki stopped and looked at him.


    "Calm down, you don''t need to be that exaggerated," Yuuki said. He looked at Hinako and asked, "Hina-chan, do you want to do something to greet your mom when she ising here?"


    Everyone looked at Hinako at the same time.


    Hinako who was being asked thought for a while. She knew that her mom wasing and she wanted to give her something special while also showing her mom that she was alright in here. "I....."


    "I want to do a drama!"


    Hinako said to everyone and thought that she should show a drama to her mom since she had decided toe to this ce and to show her growth.


    "Drama...." Yuuki, Mayuki, Chiaki, and Chiaki nodded and thought that it was very suitable.


    "Yes, let''s do it!" Kuina was excited.


    "Leave the costume to me!" Mayuki said.


    "Alright, let''s do it," Chiaki said.


    Yuuki nodded and he noticed that they were looking at him. "What?"


    "......"


    Yuuki knew that they were waiting for his answer. He nodded and said, "I will join of course."


    "Yay!!!"


    Yuuki thought that the happiest girl was the cutest one.
