It's Shirayuki's last day at the castle before her departure to Tanbarun. While she receives the proper education for the upcoming ball, Zen and the others look for the mysterious boy, Kazuki, who is after her. Zen trains every night by himself, being worried and frustrated that he can't protect Shirayuki during her trip, and Obi challenges him to earn the right to accompany Shirayuki to Tanbarun instead of Mitsuhide. Convinced of the abilities of Obi, Zen allows him to accompany Shirayuki, placing his trust in him. After that Zen visits Shirayuki to share a few moments with her before their goodbye. The next day, Shirayuki and Obi leave accompanied by Lord Marquis Haruka, and after a few days they arrive in Tanbarun where they are greeted by Prince Raji.
