Incredible chapter. Itto was able to discern that the man he was talking to was a Kurokuwa ninja before several more came out of hiding to fight Itto. Apparently they were the last of the Kurokuwa that were after Itto. He has defeated them all, but the remaining guys decided to face Itto without the Yagyu knowing. The Kurokuwa ninjas knew they couldn't defeat Itto, but also couldn't resist the Yagyu's orders, so they decided to meet their end against Itto's sword. The last man Itto faced wanted him to figure out the Yagyu secret and expose them. In his dying words he mentions silk, which made Itto suspicious of his words. Itto decides to visit a kimono vendor, who in turn sends Itto to a silkworm grower. He was able to figure out the true nature behind the letter. The Yagyu are using a mulberry extract and silkworms to write secret messages. Now that Itto has this information, he can finally expose the Yagyu and get his revenge. I'm glad he finally figured out the letter's secret. Things are heating up. I can't wait to learn what it says.
