The Most Important Symbol

From: Yui
Description: You’ve collected everything I need for calligraphy. Thank you, but what do I write? I think I’m getting even more nervous. My friend, help me one more time. Bring me some artifacts of the City - they will help me concentrate and come to the right decision.
Completed: Of course! What can help me achieve harmony, if not the character for "serenity?" The brush glides smoothly and easily, the ink quickly absorbs into the rice paper. The invisible burden disappears from my soul, and I plunge into an overwhelming calm.
