Meanwhile, back at Butler's stakeout and he has been spying on Kawata Hina for some answer for her to tell him why did you kill my master parent went he was in Korea just for fun killing his parent just because of money.
Back inside the Hinatazaka dorm where Kawata went outside to have a walk and she had her company with her along and Butler can see who is her assistant is and it was her member who is graduated from the group and her name was Watanabe Miho is assistant her for been whole this time.
Butler POV.
Watanabe Miho is her assistant why did you get involved with her and did you know what she has done in real life, of course, you don't know anything that she did because she hides her true identity just herself.
Butler: so Miho and Kawata are apart together huh?
Later Butler went inside the Hinatazaka dorm and see that she had left the dorm for a walk and entered the dorm he saw other members doing something that they are doing so far.
One of them see we have a guest coming over but they didn't recognize him only the 3rd gen Members know him and they high five each other with him.
Haruyo: Senpai why are you here...wait did you miss us?
Butler: of course, I miss you guys and how is your parent doing?
Mikuni: my parent is fine and thanks to you
Butler: no problem but there is something I want to tell you with the 3rd gen Member-only something the truth about Kawata Hina is
Mari: of course but can we go outside and go inside your car and tell us
Butler: sure are you coming Hinano?
Hinano: yes I'm coming
When the 3rd gen Member are following the Ryo Butler outside and meanwhile Kawata and Miho have returned from their walk but they didn't see them but only someone's car just park at the Hinatazaka dorm.
Kawata: did we have a guest?
Miho: I didn't summon anyone who was here today
Kawata: okay but who it is?
Miho: maybe Ayaka's father wanted to see her
Kawata: maybe you're right never mind let's go back inside
Once Butler sees that Kawata and Miho went inside the Hinatazaka dorm and he starts to talk to his true face as a psycho-acting Member who is part of Ryo Butler.
Haruyo: so what did you want to talk to us about?
Butler: did you realize something strange about Kawata Hina?
Hinano: yes we sometimes feel strange about her
Butler: well let me show you the footage that I take a video of the truth about Kawata Hina just only her and you should play the psycho acting Member but just make it real not fake okay
Haruyo: of course, we will do that just because of you and Ryo too
When Butler presses the play button that the video show Ryo went he was still in Korea and inside the Butler's car and they saw that Kawata Hina is killing Ryo's parent while he was hiding behind the bushes and didn't know what to do next by the time they left the house and they left them to die fast.
Ryo: mother...father...please don't die I need to why they did something horrible to you
Mother: they are crazy people just kill the innocent people but we love you always love you Ryo my sweet boy
Ryo: don't worry mother I will take my revenge on her for what she did
Father: my boy please take him as your Butler or you can name him whatever you want and please take care of my son for me
Out of a sudden, Butler appears in front of Ryo and he bows to him and he had a lot more mature than everyone else he stands next to Ryo and he saw his parent die for him.
Ryo: she didn't know that you mess the wrong people here and mother and father please rest in peace I always love you both now let go we have work to do
Butler: yes sir *bow*
They went to call the ambulance and the ambulance came and take the dead body away the police officer recognize Ryo and Butler and they were asked more questions about what happened to his parent.
Police: Ryo...I'm sorry for the loss of your parent
Ryo: I'm fine but I know who is the murderer!
Police: wait you know that killer?
Ryo: yes I know her but her name is Kawata Hina she is the one who kills my parent but she kills the innocent people and she is not over here but she stays in Japan
Police: thank you for your time Ryo and I'm sure Japan where you stay will find her and arrest her and put her into that jail that no escape
Butler: please do so let me excuse us my master want to take a day off
Police: of course and you can visit your parent whenever you feel to
Ryo: notice
Later the video ended and one of the 3rd gen Members is crying and one of them is angry with Kawata Hina right now but we have to wait for the final show where Butler and Ryo put her into something more killing and more terrified than she could ever she imagine.
Haruyo: how could she do that she is the crazy person that I have ever met in my life
Butler: don't worry you follow me not stay around her and Ryo wants to see you
Mari: wait...Does Butler master want to see us?
Butler: yes
While Butler was driving off to meet Ryo in person and he texted inside one of the undercover police officers who are behind her duty to stay close to Kawata Hina's case just only her case don't other people.
Butler: please continue your duty on her but please don't let her catch you red-handed
After Butler texts, she and she reply to Butler it was something more fun than usual than before she kills people went she goes to Korea.
Kegayama: she didn't notice anything yet but please do that final show fast and where is the 3rd gen Member?
Butler: don't worry they are safe with me you just focus on your duty
Kegayama: copy that sir
They ended the text with each other and Butler arrived at the Sakurazaka dorm where Ryo is inside the living room with the Sakura Member waiting for him to return here and tell him what is the next step for them to finish her very soon.
Butler: okay we are here
Hinano: why are we at the Sakurazaka dorm?
Butler: he staying here and his sister is here with him
Mari: wait did he have a sister?
Butler: yes he had one
Before Butler parking, his car and everyone inside the car went out and go straight to the Sakurazaka dorm and meet Ryo in person and they see that Butler are here with Hinatazaka46 3rd gen Member along.
Butler: I'm back sir and I bring the 3rd gen Member here to stay here until she learns her lesson
Ryo: of course she did and you must be Hinano, Mari, Haruyo, and Mikuni right?
Mari: yes I am
Hinano: why did you know all of our names?
Ryo: Butler had told me your name?
Butler: so sir I had shown them the video to them
Ryo: of course, they are psycho acting Members that put a final show to Kawata Hina
Butler: yes exactly but are you sure you doing this and this is risky your life and Morita is here with you all the time
Ryo: Hikaru are you okay I'm doing this just to take revenge both of my parent dead
Morita: of course, I'm allowed but please teach her some hard lessons and don't mess with my brother
Ryo pat Hikaru's head and he hugged her tightly right before Butler had his plan for the undercover police to come here to have set a meeting just only Kawata Hina, not her assistant Miho to come along by her side.
Butler: you can come here now!
Suddenly, the undercover police had reveal her identity to the 3rd gen Member and the same to the Sakurazaka Member is here with everyone around the living room.
Hinano: Kageyama Yuka!! Are you the undercover police?
Yuka: yes that's me!
Butler: so she didn't notice that you are the undercover police right?
Yuka: no not at all but can I send her a text saying someone wants to meet you
Butler: yes please do so
In the meantime, back inside the Hinatazaka dorm room where Kawata Hina had a text on Kageyama Yuka saying that she had someone to meet her but sadly she can't bring Miho with her and she need to stay at the Hinatazaka dorm with others.
Yuka: hey Kawata tomorrow you need to go and meet someone drug dealer at this address alone not bring your assistant with you just only you alone and meet him
Kawata: why can't bring Miho
Yuka: because he didn't trust the outsider but he trust you
Kawata: sure but I have one last question about him?
Yuka: sure please say away
Kawata: where is he from?
Yuka: good question he was born in Korea but he stay in Japan to become a gang boss but he had to retirement
Kawata: sure I would like to meet him in person but you are there with him
Yuka: yes I am but please need sharp he dislikes being hate
Kawata: of course, we will see you tomorrow and him too
Later Kageyama ended the texting with Kawata to meet her in real life but she didn't know that the place is the same as where Ryo's parents had died in his arm.
Butler: so Yuka how was it did she brought it
Yuka: of course she brought it
Butler: okay let go and make it worse you guys
Hinano: Ryo Senpai please use this before you enter the place
Ryo: don't worry I will wear this now and didn't take it off
Butler: master let's do the final show on Kawata Hina
Ryo: yes of course and Hikaru once it did you can follow me back home to visit my parent's grave
Morita: I would love to visit your parent's grave once it all had done
They all jump with a high five and everyone is doing the same with Ryo and Yuka and with the 3rd gen Member as well but Butler set up the television inside the Hinatazaka dorm where Miho and everyone inside the dorm and sees Kawata Hina truly what she has done and they can speak to her on the microphone that Butler install them.
