It had only been three months since Sasaki and his sons had entered seclusion, and they still had three months remaining. Sasaki faced a dilemma. He needed three more years to master the Chaos Dance technique, but he couldn't begin his training immediately. He had many things to consider before committing to such an extended period of seclusion.
The primary concern was intruders; someone might discover their cave and disturb his training and that of his sons. The cave's concealment relied on his sheer force, making it an unnatural and potentially detectable hideout.
Sasaki pondered deeply to find a solution but lacked any skills that could naturally hide the cave. However, with three months left, he had an idea: Kuro's Demonic Mirage technique. This skill could potentially hide the cave for the next three years, allowing Sasaki to train without worries.
