A new story arc begins! Separated from Isaku and Manji, Döa and Rin begin to lean on each other for support, with neither of them knowing that they're actually on opposing sides of a complex, generations-long conflict. As Edo's most esteemed doctors mull over Kagimura's experiments and Manji's mystical, regenerative bloodworms, Rin starts spying on Edo Castle and Kagimura's comings and goings. She knows that Manji is trapped inside, and she just needs one big clue to get her rescue operation rolling. The Edo Castle stakeout commences with "Barefoot," part one of five!
