Amazing chapter. Now we know how Retsudō has been getting his nutrients and surviving for so long without food and water. His ninjas are in the castle now and they are helping Retsudō. They are bringing him messages and doing his bidding. Abe tries to use the lamp to poison him, so they switch it out for Retsudō. Retsudō has them set a fire to the kitchen and while that's happening, Abe is spying on Retsudō. So Retsudō decides to teach him how to commit seppuku. Now that the fire occurred, Abe will most likely be ordered to commit seppuku. Retsudō is a boss even while imprisoned.
