Intro
Riku is running around inside the hideout. The passing members make way with expressions that say "here he goes again." It was a familiar sight here.
Suddenly, a loud crash rang out!
Ah, crap.
It seems he bumped into a shelf while running and dropped a vase that looked incredibly expensive, shattering it.
He scratches his head vigorously and kicks the shards away.
Whatever.
*The members watching Riku skip away from a distance are buzzing, saying "that was an incredibly expensive one."
Against the background of that noise, a familiar silhouette was walking from ahead.
Ah, it's Guest!♡
