On this day the citizens have long awaited, a young girl appeared on the great balcony of the royal castle. "It's the Princess!" "Happy birthday, Princess!" "Happy Founding Festival!" Surrounded by thunderous cheers, the Princess waves while smiling softly. That smile alone naturally brightens the expressions of the people. The star of the Founding Festival was the "Hope" of this country, the Princess. However—. On the roof of a clock tower slightly removed from the castle. Six shadows looked down silently upon the fortress. "Quite the welcome, isn't it?" Jesse, having lowered his binoculars, laughs enjoyably. "A princess loved by the whole kingdom..." Hokuto Matsumura mutters quietly while confirming the security layout of the square. "Security is tighter than expected. But, there are holes." Yugo Kochi spreads out a map and points to an infiltration route into the castle. "During the festival, the West Tower will be more lightly guarded than the main gate." Shintaro Morimoto cracks his knuckles, the corners of his mouth turning up. "It's been a while since we had a job this exciting." Juri Tanaka pulls his hat down low and smirks. "Just the fact that the opponent is royalty gets me pumped." And finally, Taiga Kyomoto quietly turned his gaze toward the Princess. The Princess, laughing innocently and waving to the citizens. Watching her, he lets out a faint smile. "...Indeed." "This mission doesn't look like it'll be boring." With those words, the six lock eyes with one another. There is only one prize. The Princess whom the kingdom protects with its life. To vanish without anyone noticing and always secure the target—that is SixTONES. Amidst the ringing of the festive music, the six began to move silently. No one knows yet. That this day of celebration will be the day that changes the kingdom's fate forever.
