if thats wat u want so here is wat i managed to write:
Kogoro got information about a organization, Conan and Haibara thinks its the Black Organization so they go with him. Haibara goes to the bathroom and leaves Conan and Kogoro. Something happens to Haibara(i don't know what)and makes her loses her memory, Haibara screams and then faints. Conan runs to the source of the sound followed by Kogoro and some police officers and they see Haibara unconscious Conan holds Haibara from the shoulder and shakes her so then she can wake up but she didn't they took her to the hospital. At the hospital the doctor says that Haibara has amnesia and that might be because of something that happened with her Conan then enters her room just to see her sleeping he didn't want to disturb her so he went out. Conan goes to where the incident happened and checks for clues but there was nothing. Then he start gathering what happened before Haibara went to the bathroom, the reason they went is only that they wanted to know information about the organization. That’s it the organization might be behind this then he dials Hattori’s number, Conan tells him about what happened with Haibara and Heiji said that they are a serial murders happening in Osaka. Conan and Heiji meet at Hakase’s house Heiji brought a new friend with him the new friend is Kuroba kaito or should I say the phantom thief kid. Heiji tells Conan that Kuroba’s father was murdered by a organization so maybe the organization that murdered Kuroba’s dad is the same organization that shrunk Conan and Haibara, Conan tells them about what happened with Haibara and that he is suspicious about organization being behind it. They team together to destroy the organization but first they go to check on Haibara. In the hospital Haibara just woke up, Conan, Heiji and Kuroba are at the hospital with Agasa they went in just to find that Haibara woke up the doctor and the nurse came in to check in Haibara and to assure her that she is in safe with her ‘family’. The doctor and the nurse left now Haibara was trying to adjust her new settlement with the new people, Agasa started telling Haibara about her life, Conan couldn’t see Haibara that way so he excused himself and went out then Heiji and Kuroba did they same thing and followed him. Meanwhile one member from the Black Organization was hiding in the hospital and was waiting till Haibara is left alone. Heiji and Kuroba followed Conan to the park, Conan sat on a bench and then Heiji and Kuroba popped out, Conan was blaming himself for not protecting Haibara her sister is dead and now he couldn’t protect her. Heiji told him its not his fault and tried to comfort him while Kuroba was thinking about the person he saw in the hospital, a nurse was staring at them till they left, then he knew its one member of the Organization he told Conan and Heiji about it and all of them ran to the hospital. At the hospital Agasa went out of Haibara’s room and left her to have some rest, the nurse then waited till he is out of sight and then entered Haibara’s room. Conan fast dialed Agasa’s phone number Agasa picked the phone now he was out of the hospital Conan asked him where he was, then told him to go back to Haibara’s room and ended the phone call. Agasa didn’t understand what was going on but he obeyed what Conan told him to do. Conan, Heiji and Kuroba reached the hospital and ran toward Haibara’s room. In Haibara’s room Haibara was starting at the ceiling trying to digest the information Agasa gave her minutes later she fell asleep, the door of her room opened to reveal a nurse with short black hair smirking at the sleeping figure, she closed the door and then took out of her pocket a gun, and loaded the bullets. Conan, Heiji and Kuroba were running Kuroba was telling them how the nurse looked like minutes of running passed till they reached Haibara’s room the door was closed Conan opened the door a few centimeters and saw a lady pointing a gun at Haibara, he then nodded to them as a sign of get ready, the pushed the door and got in the nurse turned to see 3 guys standing. Conan knew its Vermouth she removed her mask and as what Conan guessed it was Vermouth. Vermouth warned them if they stepped 1 more step Haibara (sherry) will be dead, Conan was worried and he didn’t know what to do Vermouth already knew that he might use his soccer ball or his wrist watch so she warned him. The gun is still pointed at Haibara 3 of them are worried Kuroba already managed to get the smoke bomb out of the hiding place Kuroba made eye contact with Conan to let him know about his plan. Vermouth was almost pulling the trigger when boom Kuroba threw the smoke bomb and the room was filled with pink some Conan rushed and knocked off the gun of Vermouth’s hand meanwhile Heiji ran and got Haibara from the bed and went outside the room, Vermouth was coughing she couldn’t see anything any she knew if she stayed for a while she’ll get caught she ran outside the door and went to the ladies bathroom there she placed a new disguise and walked out of the hospital. Kuroba, Heiji, Conan and Haibara were outside the room soon the smoke was over and they got in no one was there.
