Let's Go to the John (トイレにいこう Toire ni Ikō?) is the fourth chapter of the Dandadan manga series.
Summary[]
While in the middle of their training, Momo sees that Okarun has to desperately use the bathroom but refuses to allow him since it would mean that she would also have to be with him in order to suppress his curse at all times. She then explains to her grandmother that she is able to use her psychokinesis by grabbing on to the aura she sees and also tells her that she was much stronger at the time her powers were awakened. After learning this, Momo's grandmother tells Momo to close her eyes to rely on using her sense of touch to suppress Okarun's curse. Momo attempts to do as she instructed but unfortunately fails as the Turbo Granny starts to take over Okarun's body. Being unable to hold it in anymore, Okarun rushes over to the bathroom and tries to outrun Momo and her grandmother as they try to stop him. While suppressing Okarun's curse while he is on the toilet, Momo hears her grandmother telling her that her full power may be lying dormant inside her and needs further training to be able to release it. After being told, Momo notices that her grandmother's nose is bleeding and becomes shocked to find the Turbo Granny inside the bathroom. The Turbo Granny tells Momo that she is only communicating with her through Okarun and that she is able to kill whoever has laid eyes on Okarun thanks to the curse, such as her grandmother. Aware that she is training to take her down, the Turbo Granny demands to Momo that she come to the tunnel tonight or she will start randomly killing people. After the Turbo Granny makes her leave, Momo becomes able to communicate with her grandmother and Okarun again. Momo's grandmother then notices that she is bleeding and a talisman has been burnt and asks Momo as to what happened.
Before leaving for the tunnel, Momo's grandmother gives Momo and Okarun clothing that are capable of protecting them from evil spirits and asks Momo to return back alive while embracing her. While taking the train to the tunnel, Momo becomes furious with the Turbo Granny for harming her grandmother and swears to make her pay.
