Walking Heart, Breaking Heart (ウォーキング・ハート ブレイキング・ハート Wōkingu Hāto Bureikingu Hāto), originally titled Conclusion and... (決着、そして… Ketchaku, Soshite...), is the nine hundred second chapter of the JoJo's Bizarre Adventure manga. It is also the fifty-fifth chapter of JoJolion.
At the Higashikata's, Josuke evaluates the situation. Addressing Damo, Josuke concludes that the Rock Humans trafficking the Rokakaka are few, and that Damo is their head and last living member. He then warns the suffocating Damo to leave the premise immediately or Hato, currently on the roof and outside of Vitamin C's range, will defeat him. For his part, Damo looks at Josuke, the hybrid between Yoshikage Kira and Josefumi Kujo, and reflects that the new resurrecting Rokakaka will be profitable, still confident in his ability to defeat Hato. He hears her walking on the roof, seemingly following him, then dismiss her confidence.
Searching a toolbox, Damo takes a lighter and the softened Norisuke, then proceeds to throw the latter into the chimney and set him on fire. He plans to exploit Hato's overconfidence in her safety from Vitamin C and use Norisuke to infect her with his power again, stealthily going away from the chimney as Norisuke burns and Vitamin C's fingerprints reach the outside on bits of Norisuke. As Norisuke's cries bait Hato near him, Damo declares his victory but is suddenly impaled in the head from through the roof. Damo discovers too late that Josuke has hidden bubbles into his cut up liver and used them to signal his position. Impaled again by a heartbroken Hato, Damo has no choice but to flee, and everyone returns to normal, safe and sound.
Josuke spots Damo and follows the Rock Human, eventually cornering him. Damo begs Josuke to spare him, reminding him of Holy and her illness which the Rokakaka can cure, but is unceremoniously punched in the head by Soft & Wet, finishing him off. Josuke now knows his former identity, Josefumi Kujo. Unbeknownst to him, the whole scene was observed by Jobin, who witnessed Damo being killed.
At the Stone Ocean prison, a woman passes through the release procedure, being handed all the items she possesses as well as the payment for her work during the last 15 years. After putting on her clothes, the woman takes a cellphone from between two cards of her card deck and calls Jobin to pick her up, wishing to make her release a surprise to her family. Putting the phone back into the deck, the woman is revealed as Kaato Higashikata.
