Soultail: *Comes to a decision and leaving a note for Kisuke and Nagi to read, return home to face the arranged marriage*
[Letter says this:
"My friends,
I thank you for teaching me what life is like on the outside of the palace walls.
I've tried to run away from the problems at hand, yet, after talking to Nagi-san about it, I made the decision to go back home and face the arranged marrage between our enemies and our kingdom.
Please don't worry about me, I can handle it.
Until then,
Thank you and Domo arigato.
Soultail."]
