Hikari stood in her office, a rare moment with nothing to do but stare out the large glass window, glass of champagne in her hand, and admire the fireworks that bloomed against a perfect, starlit sky. Being in an underground city with an artificial sky had its perks.
She smiled, watching the city she loved so dearly illuminated in colourful lights. This wasn't an end, this was a beginning, and she was looking forward to see what the future would hold.
Of course, there were plans in motion - there always was - but for the evening, Hikari had not much more to do. Most people had gotten the evening off to celebrate, and those who didn't were directly involved with the celebrations.
Several of the idols under her care were presently at the studio to film the End of Year Music Celebration in Chime district. It was filmed a couple hours earlier so that everyone included could get back home and spend the occasion with the people of their choosing, while the broadcast would still be on the proper time.
And Hikari would lie if she said this quiet time wasn't a nice change of pace. Not that this was something she strived for, but once a year? Yeah, that felt reasonable.
